Summary of CERN and GSI collaborative developments

 

In terms of hardware development

• The  WR has been a collaboration between CO and GSI before the K agreement, and we did not change anything when the collaboration agreement came about:
  • GSI benefits from CERN's work in the core components of WR (e.g. the switch and the WR PTP Core)
  • CERN benefits from GSI's deployments in a real-life timing system, where they identify issues and work with us on fixing them and validating the solutions
    • GSI's experience in big WR deployments for GMT will be very interesting for BE-CO in the near future, as we approach that stage. Also some of the tools they have developed for operation and monitoring will be very useful.

In terms of software collaborative development between CERN and GSI

• The FESA framework
• The Device Server Framework (DSF) 
• The CMW middleware framework
• The LSA settings management, where both institutes have solid settings management systems based on the same foundations

• Despite a lot of effort, the code bases continue to diverge due to different operating concepts and machine schedules between the two institutes
• We still benefit from the work of each other (ex. adaptations to third-party libraries modifications, some non-major modifications)

            • There is a regular weekly teleconference and exchange of knowledge between the two teams which is considered useful, though it could perhaps become monthly

            • Looking to the future, there are no more collaborative developments planned at this time

 

16:10 → 16:15 Consultancy for the development of the FAIR Personnel Access System (PAS)

Speakers: Christine Betz (GSI), Jan Uythoven (CERN)

Development of a PLC software prototype for the FAIR Personnel Access System (PAS)

Fellow started at CERN to work on this in April 2020.
The addendum to the contract between GSI and CERN was fully signed about 2 weeks ago.

Summary of the work done:

The PLC hardware configuration, software and communication protocols between PLCs have been agreed upon. CERN develops the PLC software in a simulation tool (PLCSIM Advanced v3.0), testing of the software with PAS hardware is done at GSI.

•The project was split between the Beam-Off-Group and the NE areas.

      •The Beam-Off-Group is similar to CERN’s “Element Important de Security” and has to guarantee safe blocking of the beam.

      •The NE area is the actual zone to which the access has to be regulated and safety guaranteed.

•For the Beam-Off-Group the functional specification has been written by GSI. A draft of the detailed technical specification is written by CERN. The first version of the PLC software together with HMI panels have been delivered by CERN to GSI. The software is presently under test at GSI with hardware for the PAS. First results are very promising.

 

Plans for 2021:

•Delivery of the functional specification of the NE area by GSI to CERN beginning of 2021. This involves many discussions on state diagrams between GSI and CERN.

•Delivery of PLC software and HMI of the NE area by CERN to GSI

•Follow-up of test results at GSI on the actual hardware for BOG and NE Area and update the PLC code if required

•Document and finalise the BOG and NE area codes in Technical Specifications (CERN)

16:15 → 16:20 Collaborative support for Cryogenic Current Comparators for AD and ELENA

Speakers: Dieter Prasuhn (Forschungszentrum Juelich), Jocelyn Tan (CERN), Thomas Sieber (GSI)

• • CERN: Jocelyn Tan
  • Attendance at CCC collaboration meetings to keep up to date with the latest GSI developments. Request from the CERN cryogenics experts to improve this system for any future ELENA CCC, but would require additional funding. Interest from GSI for collaboration on this topic. ELENA CCC under consideration but no budget currently allocated.

16:20 → 16:25 GSI support to CERN e-lens studies

Speakers: Peter Forck (GSI), Raymond Veness (CERN)

• CERN: R. Veness
  • Ongoing GSI support for luminescence studies related to the beam gas curtain monitor for HL-LHC much appreciated by CERN. Consulting input from GSI on this topic with active participation in regular collaboration meetings and attendance at the yearly collaboration workshops. CERN would appreciate if this support could be officially maintained until at least the full commissioning of the prototype instrument in the LHC during Run3.

16:25 → 16:30 Common developments on FESA integration of beam diagnostic devices

Speakers: Marcus Schwickert (GSI), Stephen Jackson (CERN)

• • CERN: Stephen Jackson
  • No recent collaboration to date on this topic

16:30 → 16:35 Software development for Ionization Profile Monitor

Speakers: James Storey (CERN), Rahul Singh (GSI)

• • CERN: James Storey
  • CERN are active users of the IPM simulation codes developed by GSI & KEK, most recently for the PS & LHC BGI studies. The PS BGI beam data has also been compared with the IPM Sim expectations ( e.g. Beam profile vs. B-field ) with the results discussed with GSI.

16:35 → 16:40 pLinac diagnostics: Bunch Shape Monitor, SEM-Grid profile and emittance measurements

Speakers: Federico Roncarolo (CERN), Peter Forck (GSI), Thomas Sieber (GSI)

• • CERN: Federico Roncarolo
  • Consultation for the production of wire grids and information on how to define the correct bias voltage. In exchange there has been support from GSI for wire heating studies.

 

16:40 → 16:45 Collective effects and intensity limitations

Speakers: Hannes Bartosik (CERN), Oliver Boine-Frankenheim (GSI, Darmstadt, Germany)

Hannes Bartosik

Concerning the activity "Collective effects and intensity limitations”:

In collaboration with O. Boine Frankenheim and A. Oeftiger from GSI, an application has been sent to the KfB (German committee for accelerators). In addition to other aspects related to collective effects, we are proposing a PhD project on indirect space charge effects for the FAIR beams in the SIS100 at GSI and for the LHC (LIU) beams in the SPS at CERN. As the approval of the PhD project is pending, the work on this point has strictly speaking not yet started.
O. Boine Frankenheim will report in more detail during the meeting.

 

16:45 → 16:50 Advanced Landau damping for LHC / FCC and FAIR beyond octupoles

Speakers: Elias Metral (CERN), Oliver Boine-Frankenheim (GSI, Darmstadt, Germany)

16:50 → 16:55 Transverse Feedback Systems (TFS) for SIS100

Speakers: Udo Blell, Vladimir Kornilov (GSI - Helmholtzzentrum fur Schwerionenforschung GmbH (DE)), Wolfgang Hofle (CERN)

Hannes Bartosik

Concerning the activity "High performance beam simulation tools”:
This work concerns in particular a collaboration with A. Oeftiger from GSI, in which we work on the benchmarking and development of simulation tools for high intensity effects such as space charge. In this framework, we have been working on 
a) the development of space charge modules directly for Sixtracklib (tracking tool) and for a combination of PyHEADTAIL (collective effects simulations) with Sixtracklib, 
b) optimizing the simulation speed for high-performance computing architectures 
c) a study of space charge induced resonances in the SIS100

Future plans include to establish a detailed PIC model of the SPS, to develop advanced indirect space charge models and possibly to perform a joint measurement campaign of long-term space charge effects.
A. Oeftiger showed some slides on these activities during the meeting.
