L3 instrumentation SEM and FC, WU 162706
                  Code: 64050, until 03-2018.
 ITFS FC
− Manufactured,
− installation foreseen mid March
− Poor documentation generated small delays
− Budget: 20kCHF,OK

 ETL SEM-grids electronics:
−   Linear amplifier for injection (ADC sampling 4us), Integrator for extraction
−   All cards tested in the lab and installed in LEIR
−   Ready for commissioning
−   Budget: 10kCHF,OK

 ITL and ITM SEM-grids
− Delays related to poor documentation, workload and sickness of key person for ceramic
  serigraphy
− Final design completed and manufacturing ongoing. Sick person came in 1 day to do the job
− Old detectors have been re-installed
− Change to new detectors possible during 1 day oven refill ~end of March?
− Will produce 4 operational cards + 4-5 spares
− Budget 10kCHF,OK

                                                                                     3

LEIR Injection line BPMs, WU 174861
                            Code: 64053
All BPMs installed
− 2 BPMs in EI line still not under vacuum
− ETL line BPMs (5), baked out and tested with calibration
  signals
− Cables pulled for repelling voltages and magnets
Secondary's:
− Intensive simulations and measurements done
− Physics ~understood
− BPM1 with dipole magnet, still need to verify
  effectiveness in second plane, BPM2 with solenoid
− All BPMs with repelling voltages
Improved EMI suppression in tunnel
FESA class operational
Acquisition system in control room still to be
cabled
Budget: 30kCHF 2018 for secondary electrons /
ions, OK
                                                                 4

LEIR orbit system
                                                                                                    Stdev orbit: new system (red)-old system(blue)
                        Average orbit: new system (red)-old system(blue)                         Much better stability of the orbit readings

                                                                               Hor. stdev (mm)

                                                                               Ver. stdev (mm)
                                                                  Early beam at “1000ms” Averaged over 42 cycles
                     • Trajectory:
                      • Struggling since November with latch up of GPT link for Sushi train (inter card link)
                          − Versioning of VHDL modules was not clear, and back tracking was slow.
                          − Change of firmware in RF group
                      • Positive collaboration with J. Mollendijk (BE-RF) to solve these issues
                      • Blocked the debugging of the trajectory firmware
                      • Problem now “solved”, with the possibility of detecting and resetting of latched PLL
                      • Aim to have new orbit and trajectory firmware operational beginning of April
                      • FESA class upgrade needed (auto addressing of memory maps + trajectory)

                                                                                                 BE-BI LIU-ION review 12-03-2018                     5
