41. Access to the CERN accelerator complex during LS1

After a brief summary of the function of the CERN accelerator complex access system, the talk will summarize the feedback of the LS1 period. It will especially highlight its availability and possible improvements required by the users. The lessons learnt from this exercise and the experienced bottlenecks will be outlined.

36. Activities on warm magnets

Davide Tommasini (CERN)

Despite the fact that the LS1 was triggered by the consolidation to be carried out on the LHC superconducting magnets, a huge amount of work took place on the resistive magnets in the whole CERN accelerator complex. The experience gained and the lessons learnt during LS1 are a good basis for the LS2 that will contain a large proportion of activities in the injectors, especially to provide...

33. EN-CV activities during LS1

Mauro Nonis (CERN)

The talk will first identify the main activities used to structure the group activities during LS1, distinguishing between those internal to the group and those carried out for other groups. Also, activities belonging to recurrent maintenance and to consolidation will be differentiated. The support received and necessary infrastructure will be presented. The impact of safety, access and...

32. EN-EL activities during LS1

The talk will first identify the main activities used to structure the group activities during LS1, distinguishing between those internal to the group and those carried out for other groups. The support received and necessary infrastructure will be presented. The impact of safety, access and co-activity constraints will be identified. Based on this, lessons learnt during LS1 from the EN-EL...

37. Experiments

Austin Ball (CERN)

Although LS1 was triggered by consolidation needs in LHC, it has also included intensive activities in the LHC experiments, with substantial maintenance and consolidation work overlapping with the first stages of upgrading for higher luminosities. After a brief summary of these activities, the talk will focus on feedback concerning the management of the machine-detector interfaces and the...

43. GS activities during LS1

The talk will summarize the feedback of the LS1 period for the activities under the responsibility of the GS Department, in particular Access Systems, Alarm Systems, Fire Brigade, Civil Engineering, Logistics, Stores and other site services. After a brief summary of the concerned activity, the talk will highlight its performance/availability, the lessons learnt and the possible improvements...

29. Introduction

Frederick Bordry (CERN)

After reminding the scope and some key figures of the LS1, the talk will focus on what worked well during LS1 and fir which reasons and also on things that could be improved or done in a better/different way.

21. Questions

20. R2E

Katy Foraz (CERN)

30. Safety

Thomas Otto (CERN)

After summarising the LS1 results in terms of safety, the talk will focus on the necessary preparatory work to achieve these good results. It will stress the importance of pragmatic solutions, giving examples and also of clear and stable safety rules. Surface activities will also be treated. Radioprotection aspects will be presented, outlining expected differences for LS2.

34. Survey activities during LS1

After a brief summary of the activities carried out by the survey team during LS1, the talk will explain how the general organisation for LS1 was defined. It will outline the supporting infrastructure that was used. The constraints generated by the coactivity with other activities like ElQA, hardware commissioning, will be outlined analysing especially the safety and schedule impacts. To...

31. TE-EPC activities during LS1

Jean-Paul Burnet (CERN)

The talk will identify the main activities used to structure the group activities during LS1. Then the work carried out in the frame of R2E and its organisation will be described, highlighting the advantages and drawbacks of such a way of working. Difficulties encountered like coactivity, limited access conditions and cleanliness issues will be presented. The feedback from the work carried out...

35. TE-VSC activities during LS1

Paul Cruikshank (CERN)

The talk will first explain the method applied to structure the group activities during LS1 in the entire CERN accelerator complex. It will highlight the dependencies with other groups and their impact on the work organization. It will also present the support received and used infrastructure. Lessons learnt during LS1 and possible improvements coming from difficulties encountered will be...
