SAFETY 30/7-018 - Kjell Johnsen Auditorium
Scientific Secretary, Ghislain Roy
Convener: Ralf Trant (CERN)-

Early Safety Management of Projects and Experiments20'+10' CERN has a unique position as an International Organization across the Franco-Swiss border. Ensuring Safety of projects and experiments, sometimes coming from afar, requires a clear, concise and effective approach to Safety management. The most important challenge is to introduce Safety management as early as possible in a new project or experiment. Tools and methods are being developed that ensure that ownership and safety responsibilities are clearly defined, that applicable rules and procedures are available and known, that proper Safety documentation is written in due time and made available, and that that Safety is managed through the entire lifecycle of the project or experiment. This presentation will show examples and will present the path to achieve CERN-wide application in the near future.Speaker: Mrs Isabel Bejar Alonso (CERN)

ALARA Experience and Lessons Learnt20'+10' The ALARA (As Low As Reasonably Achievable) principle is a radiation protection and radiation safety principle, which aims to minimize radiation doses and releases of radioactive materials, through the use of all reasonable methods. CERN has adopted a structured approach to ALARA in 2006, with the goal to optimize work coordination, work procedures, handling tools, and even the design of entire facilities. Consequently, a close collaboration between RP and many departments in CERN is required. This talk will give an overview of the ALARA principle at CERN, and will show examples of the way that it is applied in practice. Finally an overview of the project "RP guidelines for the use of materials in accelerators and experimental facilities" will be presented.Speaker: Heinz Vincke (Unknown)

Safety Consolidation in and around the Accelerator Chain20'+10' Following the decision taken in 2010 to run the PS for another 25 years, two safety-focused working groups were launched to assess the needs for consolidation with respect to the radiological impact on the one hand, and the technical safety matters on the other hand. This presentation summarizes the findings and recommendations of the two working groups, and outlines the process foreseen to follow-up on the recommendations.Speaker: Simon Baird (CERN)

Evolution and Future of Access Safety and Control Systems20'+10' The Access Safety and Control systems of the PS complex are being completely redesigned in the wake of the design and installation of those for the LHC. New hardware and functionalities are due to appear in the coming year, but most of the existing sectorisation and architecture will survive the change. Following the PS, the experimental areas and SPS are next in line for this overhaul. This presentation will show how the new access safety and control systems (PS, SPS, Experimental areas) will compare to what we have learned to know and love: new functionalities, lost functionalities. The point of view of the operating teams will also be presented with an outlook on potential grand-unification of access rules and procedures.Speaker: Rende Steerenberg (CERN)
-
7
Evolution of Radiation Monitoring20'+10' Radiation and environmental monitoring systems need to be constantly adapted to the ever-changing environment of CERN. This talk will present the achievements of the RAMSES II Light and ARCON-Bridge projects, completed in 2010. The objective of the RAMSES II Light project was to reinforce the reliability of radiation monitoring for the LHC Injectors, whilst the objective of the ARCON Bridge project was to unify and strengthen the ARCON and RAMSES radiation supervision systems. This presentation will also provide an overview of the works to be carried out in 2011 to consolidate radiation Area Controllers (ARCON) in the period before RAMSES II is operable. The evolution of the radiological monitoring system is a key motivating factor for the future.Speaker: Millan Gustavo Segura (CERN)
-
8
Safety Management of Shutdowns20'+10' Safety management is integrated into the general management, organization and coordination of the shutdown activities. Using the SPS as an example, the different aspects of shutdown management that have an impact on Safety will be reviewed; starting from documentation and job planning, through the available tools (forms and electronic forms, meetings, site visits, etc.) and safety equipment, training, communication, and all the way to the signature of the “beam permit” and the collection of lessons learnt, looking for improvement year on year. This presentation will demonstrate that Safety is not intended to make it harder or more difficult to do our work, but it serves to ensure that work is done without undue danger to ourselves, our colleagues, and our equipment and accelerators.Speaker: David McFarlane (CERN)

MTE Roadmap - Beam Physics Aspects20'+10' The situation after the 2010 physics run will be briefly summarised, discussing, possibly, also the latest results obtained in 2011. The plans for the studies in 2011 will be reviewed including also a longer-term analysis of activities to be carried out during the first long shut down and how to re-start after the long stop.Speaker: Dr Massimo Giovannozzi (CERN)
-
10
MTE Roadmap seen from OP20'+10' The MTE has been tested and used in both PS and SPS. Two main concerns, important activation of the PS extraction septum and a periodic fluctuation that results in a degradation of the trapping efficiency contributed to the decision to revert to the CT extraction for the production of the SPS fixed target and CNGS beams. However, once the previously mentioned concerns are mitigated, the MTE has many advantages over the CT extraction for day-to-day operation. This presentation gives an overview of the OP point of view on the plans to make MTE operational. It will address the requirements on the beam parameters, tolerances and margins for the MTE beam in the SPS together with milestones and proposed means to achieve these milestones.Speaker: Rende Steerenberg (CERN)
-
11
Requirements and Constraints for ABT Equipment20'+10' Experience with MTE during the 2010 run has shown that improvements are needed for sustained use of the MTE in the future. In particular the extraction equipment is strongly affected by the requirements that come forward from the results of past and future MTE studies. The presentation will discuss the impact of the various MTE scenarios on the newly installed MTE kickers, the CT equipment and additionally required equipment. Controls modernization, spare requirements as well as resource needs and planning issues will be addressed.Speaker: Mr Jan Borburgh (CERN)

BI Improvements across the Complex20'+10' A consolidation program for the beam instrumentation of the LHC injector chain was started by the BE-BI Group several years ago. The recent MTE and LIU projects have added new requests which now have to be integrated into these renovations. This presentation will give the status of the ongoing activities and discuss what has been identified as additional possibilities for upgrades on the different machines.Speaker: Mr Jean-Jacques GRAS (CERN AB-BDI)
-
13
High Intensity Beams and their Performance20'+10' The number of users, requiring high proton fluxes keeps on increasing. In this presentation we discuss the implications of the high intensity running on the accelerators, the super cycle composition and the scheduling.Speaker: Karel Cornelis (CERN)
-
14
Machine Interlocks20'+10' Like many other systems, the Machine Interlocks (MI) initially conceived for the LHC and presently in operation are/will be deployed to the Injectors. The presentation gives an overview of the main functionalities and reports on the operational experience with the MI systems. Two MI components are mainly considered here: the warm magnet interlock system and the beam interlock system. For the latter, the links with both Software interlock and Timing systems are more particularly detailed. Besides, a deployment status is presented concerning the MI systems currently in operation together with the timetable for future implementations.Speaker: Mr Bruno Puccio (CERN)

What Future for the PS East Area and nTOF?20'+10' We describe the issues with the present East Area and the motivations to propose a new layout for the beam lines and associated experimental areas. Now that this area may have to operate for several more decades, an evaluation has also been made of the required interventions and their costs for ensuring that this continuation can take place in good conditions. Some particular attention will be given to the irradiation facility located in this area, in particular in view of the AIDA project that foresees an upgrade of this facility. Finally the nTOF running in 2010 and prospects for 2011 will be briefly described.Speaker: Lau Gatignon (CERN)

16
How to ensure a bright Future to the AD Machine20'+10' During more than 10 years of regular operation, the AD has supplied the successful physics program with low-energy antiproton beams. For the medium and long-term future, several options exist for upgrades and consolidation of the facility as well as for extension of the physics program. This talk will deal with present and future projects, status and impact of the ELENA post-decelerator and finally issues related to consolidation of the existing AD machine and experimental hall.Speaker: Mr Tommy Eriksson (CERN AB/OP/AD)
-
17
ISOLDE in 2011 and beyond20'+10' The first part of the talk will report on safety improvements in the ISOLDE facility and on the issues encountered during this exercise. The talk will then focus on the facility upgrade ongoing, HIE-ISOLDE, reporting on status, issues and plans. Of particular interest, the talk will state about the timetable and resources compatibility between the future HIE-ISOLDE installation and the planned LHC shutdown in 2013, highlighting possible conflicts and alternatives.Speaker: Yacine Kadi (CERN)

Experimenters' Dreams for Future Facilities20'+10' An overview of possible future experimental area projects will be presented. The status of these projects ranges from mature ideas that have been already presented in the CERN scientific committees and are in the approval process, to experimental ideas that are at the conceptual design phase. The variety of projects being discussed covers almost all the CERN accelerators experimental areas and budget spectrum. For completeness the present and future of the non-accelerator based experiments will be presented.Speaker: Ilias Efthymiopoulos (CERN)
-
20
HiRadMat Knocking at the Door20'+10' The talk is meant to report about the readiness of the HiRadMat facility to start operation in 2011. Status, commissioning and operation plans for 2011 are the key-points to be highlighted during the first part of the talk. The talk will then focus on the lesson learned from WARF / T9 target area dismantling, which involved ALARA procedures and radioactive waste treatment and highlighted some critical design features.Speaker: Ans Pardons (CERN)

CONTROLS in the INJECTORS 30/7-018 - Kjell Johnsen Auditorium
Scientific Secretary, Bettina Mikulec
Convener: Eugenia Hatziangeli (CERN)-
21
INCA - The Point of View of the Main Users20'+10' InCA (Injector Control Architecture) is the new control system built for the LHC injectors which integrates LSA (LHC Software Applications) as well as new functionalities. After an intensive phase of validation and use on LEIR during the year 2009, recommendations and wishes have been formulated for an improvement of the deployment, the communication after release, the configuration and of the diagnostic tools. In 2010 it was deployed on CPS, a more complex machine than LEIR, with less difficulty and more confidence. The presentation will cover the current status of InCA, the feedback of the main users, the follow-up of the issues, the possible improvements and recommendations for the PSB deployment of InCA in 2011. A draft of the future plan of deployment on other accelerators will be also presented.Speaker: Mr Sergio Pasinelli (BE/OP)
-
22
ACCOR: What will change for Operation and Equipment Groups?20'+10' The presentation covers three major aspects related to the ACCOR renovation project. The impact of the new LHC schedule on the Injectors renovation planning is one issue that will be addressed. In addition, the renovation process strategy put in place by ACCOR will be laid out. This regards the active involvement of the three main parties CO, OP and the equipment groups, in which the required commitment of the equipment groups will be emphasized. The third main point of the presentation will be the new front-end responsibility model, its applicability in practice and the implied consequences for the equipment groups and operation during exploitation.Speaker: Anastasiya Radeva (Unknown)

23
Industrial Controls in the Injectors - "You (will) know that they are here"15'+10' Industrial control components are widely used at CERN, either in complete industrial vertical solutions covering the three tiers, or as one of the tiers such as PLC for acquisition layer or PVSS SCADA as user interfaces. The objective of the presentation is twofold, first to describe the present ICE operational support for the already deployed industrial components both hardware and software with a special focus for the injector, then to present the industrial control development plan for the renovation of the complex.Speaker: Herve Milcent (CERN)

Databases for Operations of the Injectors - Overview, Dependencies and Strategy for smooth Upgrades of Data-Driven Controls System20'+10' The presentation will give a brief overview of the main data domains (data for the installed components, controls configuration data and operational data) and corresponding databases used for the Injector Chain controls and operation. The state and ongoing development in some of the data domains will be shown. The presentation will cover as well the interdependencies between the different databases and look at the challenges of a data-driven controls system in a distributed databases environment. The strategy for smooth, authorized upgrades of the controls systems based on data changes propagated through the databases will be discussed.Speaker: Zornitsa Zaharieva (CERN)

25
PS & PSB Cycle Management Reviews15'+5' In the PS complex, the current number of timing users available is limited to 24. This maximum cannot be increased easily due to hardware limitations. While solutions to replace the hardware exist, it would be very difficult to deploy it before the 1st long shutdown (LS1). In addition, it has been requested to provide double batch LHC beams from 2011 on, worsening the situation especially in the PS Booster (PSB). During the start-up 2011, PS & PSB OP decided to reassign several timing users and to use them as generic containers. This decision changes the way of operating the machines and had brought up other issues that were not expected at first. In the short term, we still need to find the best solution to control the handful of PS devices that have settings depending on the number of PSB rings used. In the medium term, the timing renovation will ensure the new concepts are integrated in the timing system.Speaker: Stephane Deghaye (CERN)
-
26
Samplers in a 3-Tier Control System: Plans and First Experience15'+5' Presently analogue signals of the accelerator components are acquired using two systems, OASIS and samplers. The second is widely used in the PS complex and with the introduction of the new MEN A20 platform the strategy for the deployment and renovation of samplers has been reviewed. This presentation will briefly outline the ACCOR strategy for analogue signal acquisition, in particular the part concerning the samplers, followed by a summary of the main functional requirements. The first development and implementation following the new strategy took place in CTF3. A first return on experience will be discussed.Speaker: Rende Steerenberg (CERN)
-
27
Application Development for Operations in the Coming Years15'+5' At Chamonix 2011 draft planning for the coming years included a long shutdown spanning 2013 and part of 2014. The entire accelerator complex will not be operational for most of this shutdown. Operations manpower will be redeployed during the shutdown to support the major LHC consolidation effort and other shutdown activities. Operations has traditionally performed application development to support accelerator operations. Some development will certainly be required during the shutdown to support maintenance and development of software for the existing accelerators. Development will also be required for new activities: LINAC4; LINAC4/PBS connection; HIE-ISOLDE. An estimate for the required resources for application development during the shutdown is presented. This is weighed against the demands of other shutdown work. Alternative sources of manpower are examined.Speaker: Mike Lamont (CERN)

LINACS 30/7-018 - Kjell Johnsen Auditorium
Scientific Secretary, Federico Roncarolo
Convener: Oliver Bruning (CERN)-
28
Linac2 Performance Review and Linac2 Hardware Review30'+10' CERN's Linac 2 accelerator is the source of all primary proton beams and it has been in service since 1978. Depending on which scenario is assumed for Linac4 connection to the PSB, reliable operation will have to be ensured until up to 2017-2018 at the latest. The present talk gives a summary of 2010 operation, a snapshot of the current Linac2 performance and an outlook to potential performance levels during MD studies in 2011 with a critical overview of the status of the various systems involved (RF, source, vacuum etc). Estimated requirements for reliable operation in the future will be balanced against the ongoing or planned consolidation projects. An assessment of what can be realistically delivered in the future vs clients' requests, and of possible margins for operation improvements vs most critical risks will be finally attempted.Speaker: Giulia Bellodi (CERN)
-
29
Linac3 Source Status25'+5' This presentation will begin with a review of the 2010 Linac 3 ion source in terms of efficiency, stability and reliability. More in detail, the lead ions oven capacity and efficiency will be discussed, addressing possible improvements of the lifetime and the turnaround for refilling, given the two interchangeable ovens. The advantages of having a third oven will also be considered. In visage of new ion beam types that will be requested in the short/medium term, it will be necessary to schedule MD time to validate the source and the linac, and review the consolidation/upgrade of equipment and diagnostics. The presentation will also review the possible operation at different ECR frequencies (14-18GHz), including the status of the plasma chamber damage, shorts happening at the intermediate electrode and the general spare parts policy.Speaker: Richard Scrivens (CERN)

Middle-Long Term Needs for Ion Beams25'+5' The requests of various ion species (Pb, Ar, Xe, U) from the users ALICE for ion-ion, proton-ion and deuteron-ion collisions, NA61 and NA63 for fixed target physics in the North Area, and studies of medical treatments are reviewed. Taking into account the time needed to commission new ion species in the complex, and assuming presently known dates for the long LHC and injectors shutdowns, a roadmap for the CERN machines over the next ten years is derived.Speaker: Mr Stephan MAURY (CERN)
-
31
Linac4 Source25'+5' According to the Linac 4 design parameters, the H- source is expected to deliver 400 us pulses with an average current of 80mA at 45 KeV, at a frequency of 1 Hz. The RF driven volume source presently installed at the 3 MeV test stand has been conceived as an upgrade of the 35 KeV, 50mA source used at DESY. The commissioning at 35 KeV has been completed and the problems encountered for the 45 KeV H- upgrade will be discussed. The source has been now converted to a 45 KeV proton source and will be used for the RFQ and chopper commissioning. In the frame of the plasma generator work package within the SLHCPP project, a 50Hz, 1.2 ms, 100kW, 2MHz RF test stand was developed and a multi kW plasma generator derived form the DESY volume source was designed, produced and tested. A crash program has been initiated to provide a new Linac4 source design. The new source development compatibility with the different Linac4 installation scenarios, the needed resources and main road map will be described in detail.Speaker: Jacques Lettry (CERN)
-
32
Linac4 Connection Options and Possibilities as a Backup for Linac225'+5' Assuming that the Linac 4 connection to the PSB will be scheduled earlier than 2016 and that a 45 KeV H- source will not be available, it would be necessary to use the new linac with protons. A first option could consist in injecting at 50 MeV to cope with the Linac2-PSB injection equipment. For such an option, this presentation will address the maximum achievable performances in terms of beam intensity and brightness, together with the possible show-stoppers/bottlenecks. A second possibility would be to inject protons at 160 MeV, for which the implications in terms of PSB injection region modifications need to be considered. For both cases, the intervention time for equipping the linac as proton injector will be discussed.Speaker: Alessandra Lombardi (CERN)

CONSOLIDATION and UPGRADE PLANS for the INJECTOR COMPLEX 30/7-018 - Kjell Johnsen Auditorium
Scientific Secretary, Malika Meddahi
Convener: Roland Garoby (CERN)-
33
EL Consolidation and Upgrade of Infrastructure15'+5' The power network at CERN needs consolidation because the oldest part is now more than 40 years old and because the network has to follow the evolution of energy demand. The program is huge and need to be run in a coherent way. Therefore EN/EL is working on the 2025 network which is the long term objective of the network consolidation. The main items of the 2025 vision are: - Renovate 18kV cables and substations for SPS - Bring 66kV to Meyrin site - Reorganize normal and secured network in Prevessin anticipating new projects. - Separate “machine” and “general services” networks in Meyrin - Keep redundancy on Power transfos 400/66kV EN/EL is eager to share this vision with all users and need from them a feedback in terms of power demand forecast.Speaker: Francois Duval
-
34
CV Consolidation and Upgrade of Infrastructure15'+5' With the operation of LHC several actions have to be taken to ensure the required reliability of CV installations in LHC as well as in the injectors’ chain. Unless modifications required for the upgrade of some machines, such as the PS Booster, most of the work shall focus on a major refurbishment of almost all plants. The paper shall present the most important interventions, i.e. the ones having a major impact in terms of schedule, cost and resources required, with a special focus on the actions that should be taken during the first long shutdown in 2013.Speaker: Mauro Nonis (CERN)
-
35
LIU Baseline Beam Parameters and Planning15'+10' The goal of the LIU project is to make the LHC injectors capable to fulfill reliably the needs of the HL-LHC, including margin for flexibility and degradation between injection and collision at high energy in the collider. The corresponding beam characteristics have to be within reach of the possible improvements of the injectors. A tentative set of parameters satisfying these criteria will be presented, together with a preliminary planning.Speaker: Roland Garoby (CERN)
-
36
Possibility to Connect Linac4 during LS115'+10' A schedule for connecting Linac4 to the PSB during a 19-month LHC shutdown starting in January 2013 has been worked out and agreed by the main Workpackages involved. The Linac4 commissioning schedule in 2013 remains basically unchanged, whereas commissioning of the transfer line, modification of the PSB injection region and re-commissioning of the PSB take place in early 2014. Modifications to the present injection would start only in January 2014, after assessing performance and reliability of Linac4 at the end of the commissioning phase, as well as the remaining operational risks. The goal of the early start-up would be providing from 2014 the same beams out of the PSB as presently with Linac2. A preliminary estimate of required resources and interferences with other projects/activities will be presented for discussion.Speaker: Maurizio Vretenar (CERN)

Plans for the PS Injector20'+10' Plans for the upgrade of the PS injector are presented. The baseline scenario consists in a consolidation and upgrade of the existing PS Booster. The PSB upgrade can be broken up in the upgrade of the injection (H- injection from Linac4) and a possible energy upgrade of the machine from 1.4 to 2.0 GeV. As an alternative, a feasibility study for the replacement of the Booster by a Rapid Cycling Synchrotron (RCS) has recently started. Both scenarios are presented along with time lines and resource requests, notably for the first long LHC shutdown.Speaker: Dr Klaus Hanke (CERN)
-
38
Plans for the PS20'+10' In the framework of the injectors upgrade, the PS should provide in a reliable way the beams required by the HL-LHC. An overview of beam studies that will be carried out during the next years, both in terms of MDs and simulations, to determine as best as possible the future performances and limitations of the machine, will be presented. The hardware modifications necessary to improve and upgrade the LHC beam production will be discussed: this will include the consolidation of various systems necessary to assure reliable operation also for the non-LHC beams. A preliminary list of possible activities for the next LS1 will be also presented.Speaker: Dr Simone Gilardoni (CERN)
-
39
Plans for the SPS20'+10' An overview is given of the plans for the SPS consolidation and SPS-LIU upgrade work. The baseline work and options still under consideration are described, and placed in the context of the present technical stop and long shutdown schedule. Preliminary resource estimates are given where possible and potential manpower concerns highlighted for the main activities, especially during LS1. The SPS-LIU MD objectives are outlined for 2011.Speaker: Dr Brennan Goddard (CERN)
