CERN, CCC Conference Room

54. Strategy

Steve Myers

03/03/2008, 08:30

- Achieve circulating beam as soon as we have a cold and minimally commissioned machine. - Commission with beam to demonstrate that the machine is viable (captured beam and 1 hour lifetime). - The first run for physics. - The fall back solution: - One or more sectors require a major repair and have to be warmed up. - Sector test from one side or both on several healthy...

56. HWC– where are we?

Roberto Saban

The major non-conformities encountered, the ongoing work, repairs, etc. (PIMs, connection cryostats, coupling between bus-bars, water cooled cables and flexible connections, etc.). The planning for the coming months.

57. Overview of the commissioning of 45

Bellesia Boris

03/03/2008, 09:20

- Where we come from (a recall of sector 78) - What was achieved in sector 45: number of circuits, energy of the presently commissioned sector 45, - how much more do we need for a reasonable energy level

58. Issues arising from review and HW commissioning strategy over the coming months

Rudiger Schmidt

03/03/2008, 09:40

o safety, access, resources (qps, interlocks, power converters, MPP, controls), availabilty of systems, etc o Lessons from sector 4-5 o Parallelism between HWC and machine checkout (partial & full) – resources, expertise, limits

59. HW commissioning to intermediate energy

Antonio Vergara-Fernandez

03/03/2008, 10:30

o How can we achieve a machine commissioned for beam operation for mid June? o Objectives, advantages of HWC to intermediate energy. o How much time can we gain? o Can we achieve a commissioned machine for intermediate energy by mid-June? Critical issues for that? o Is there a safe limit to operate the magnets and the cryogenics for cold check-out, early physics?

60. Access System

Dr Magali Gruwe

03/03/2008, 11:05

o What is going to happen in the next 6 months? o Present experience o Closure of ring, preparation, qualification etc. o Prerequisites, EIS… o Access during a sector test o Is the access system ready for HWC in parallel to a sectorized cold-check out in parallel to HWC and experiment preparation?

61. Experiments during HWC, beam tests and initial commissioning

Massimiliano Ferro-Luzzi

03/03/2008, 11:35

o What are the experiments going to do from March to the first collisions o Can they leave with controlled access in the experimental areas in parallel with HWC and Cold-Check-out o Impact of a Sector test o How interested are the experiments in a run at intermediate energy?
