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.

Cost: External Funding Phase 1
The missing income of 0.7 MCHF should be covered through new applications: Belgian Big Science Project #2 through K.U. Leuven => Phase-2 Local funds from Sweden through U. Lund COSA EU-FP7-ITN Innovative Doctoral Program 24 man x years
(*) to be considered additional expenses on salaries of 6.0 MCHF (2011-2014) already covered by EU-FP7-ITN Marie-Curie program: CATHI

Missing Resources for Phase 1
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
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 of: 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.

Cavity Test Results
Comparison of HIE ISOLDE and ALPI QWRs
Data from Legnaro vertical test courtesy of Anna Porcellato
The slope of our best cavities is independent on Q0 and close to the best ALPI cavities (rounded substrates) Q2_7 ranks 9th out of 13 in terms of Q0 and initial slope
Looks as if we were entering the distribution of the LNL cavities from below

Summary
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
