Phase 1 Updated Schedule

Initially planned to start in May 2015, the Physics Program at 5.5 MeV/u is now expected to start in October 2015. The above schedule is could be affected by unforeseen emergency activities that could arise during LS1. Reprioritization of phase 2 and 3 is unavoidable.

Missing Resources for Phase 1

5

For the CRYOMODULE: HR needs (8 man years) All of these needs (the 5 man years listed above) have been filled by redeploying personnel from other projects. However, a short-term (3 year LD contract) position is requested to ensure the continuation of the experienced Mechanical Engineer currently assigned to the HIE-ISOLDE project beyond July 2013.

Missing Resources for Phase 1

6

For the CRYOGENIC PLANT: HR Needs (2.3 man years)

• HR needs are estimated to a total of 8.3 man years for the period (2013-2015).

The need is for Engineers and technicians to be involved in “Cold box reinstallation” and “Compressor station reinstallation” mainly in the activities

• f: Project engineer, Mechanics/drawing, Process control, Instrumentation and

Commissioning.

• All of these needs but, 2.3 man years, have been secured for the project.

For the Beam Instrumentation: HR Needs (2 man years)

• HR needs are estimated to a total of 2 man years during the period (2013-2015).

Two electronic engineers are needed for a period of 12 months to develop: (i) the front-end analogue electronics for the Faraday Cup (in intensity and profile measurement modes) and the Silicon detector and (ii) the motion control for the beam diagnostic boxes.

• All of these needs will be filled by redeploying personnel from other projects.

Summary

11

Most recommendations of the previous cavity review were implemented:

• Reconsidered mechanical tolerances
• 4 prototypes available since summer 2012
• Focused on dc bias sputtering
• Dummy copper cavity available and used for sample studies in autumn 2012
• Increasing cavity turnaround up to 2 weeks
• Setting up a backup test place in Orsay
• Continuing work on cavity ancillaries (tuning plate, coupler, RF line)

Cavity performance improved significantly in one year:

• 1 MV/m @ 10 W in September 2011
• 5 MV/m @ 10 W in October 2012

Remaining issues for cavity performance

• Film thinness on cavity top (high current region)
• Bad film quality on tip of the inner conductor (peak E field emission)
• Stability
• Statistics
