Julie Coupard, LHC Performance Workshop, 25 th September 2014

Session 8 - Long Shutdown 2 Strategy and Preparation

LIU Planned Activities

Reference : RLIUP Oct.2013 (indico) “Work Effort in the LHC Injector Complex, including Linac4 connection, for the Upgrade Scenarios” J.B. Lallement & B. Mikulec

The baseline LIU installation activities corresponding to both ion and proton upgrades will be described for the whole injector chain. The additional possible installation activities linked to the pending options on which decision will be made during 2015 will also be reviewed. It will be examined whether any of these activities can be anticipated to earlier shutdowns or postponed beyond LS2, emphasising the consequences on beam operation and the preparation and performance reach of the LIU beams for HL-LHC. The corresponding support needed from the various CERN groups together with the required technical expertise will be estimated. Finally, a preliminary LIU installation master schedule will be presented.

Technical coordination organizationNew structure

MandateThe Technical Coordinator of the LHC Injectors Upgrade Project has the following functions:

1. Generate the detailed schedule of the hardware works relative to the LIU project within the assigned time constraints;

2. Plan the necessary manpower and coordinate the different teams in order to set up the logistics and permit the smooth execution of the works;

3. Ensure that the so defined time and manpower planning does not clash with all other concurrent activities potentially involving access to the same zones and/or the same teams;

4. Manage and follow-up the scheduled work during shutdowns and technical stops.extract EDMS 1410283 - LIU-PM-QA-0011

Preliminary Master Plan to be detailed by machine and coordinated all together (resource levelling)

First remarks• The PSB upgrade is the critical path of the LIU project in term of workload on site.• Connection of the Linac4 has to be scheduled at the most appropriate time

according to the manpower needs• RP conditions to work in machine area according to beam operation in other has

to be identify (Linac3, dismantling of Linac2?)

Conclusion

All work activities listed in the scope of the LIU fit in the LS2 time window defined for the injectors but the schedules are very tight with no many margins and shift activities.

Decisions on non priority consolidation works have to take into account the LIU activities.

Additional studies have to be done:• All new cabling request (DIC) need to be done as early as possible in order to estimate the

EN/EL workload and integration.• Evaluation of manpower usage in all CERN complex (LHC, Injectors), mainly for

support/client groups : EN/MME, EN/HE, EN/CV, EN/EL, EN/MEF-SU, TE/VSC• Design and production plan to be defined in order to be coherent with the schedules of

installation• Integration studies to be completed (3D models of infrastructures, general services)• Definition of all works that can be anticipated in YETS and EYETS in order to reduce the

workload for LS2 (i.e. dismantling, decabling …)
