AWAKE p+ beam line HWC C. Bracco, J. Schmidt Acknowledgment: MCS, EPC, MPE, SPS-OP, BI, ABP (survey),STI, EA, ACE, RP
2
Planned Activities Vacuum: – Leak detection, pumps and gauges, valve movements Diagnostics (BPMs, BCTs, BLMs and BTVs): – Functionality, calibration and logging BIS: – Vacuum, valves, laser dump, beam stoppers TBSE, extraction kickers, MBI and MBG current, WIC, FMCM, SIS (Maskable and un-maskable). – Logic for AWAKE and LHC extraction. Magnets, PC and WIC

4
Vacuum Everything ready and ok for proton beam line Plasma cell sector still to be pumped down + leak tests (10 th -13 th June 2016) Interlocks for all installed valves ok and data logged in TIMBER.
5
Diagnostics 1/2 BLM – Logging done – OP application done (threshold: loss level to be defined) – Layout positions defined – Need to check interlock (BIS) BCT – Logging OK – Calibration set-up done BPM – Firmware available since last week – Electronic cards installation on Tuesday 7 th June 2016 – FESA server software development and test on-going – YASP integration ready – Logging done
6
Diagnostics 2/2 BTV – Downstream of plasma cell: fully OK – Upstream of plasma cell: missing filter wheel and flip mirror (week 24) – Logging OK – OP application OK STREAK – No data before August – Logging to be done
7
BIS User input commissioned and conform: – Vacuum TT41 & valves – Laser Dump – WIC TT41 – FMCM RBL 410010 – FMCM RBL 410147 – TBSE TT41 User input not yet commissioned: – TT41 converters current – MBI current (need new SW) – MBG branch current (need new SW) Enable all inputs at the BIS level (removed the disable jumpers) and check the BIS master equations (half a day in week 24).
8
Magnets, PC and WIC (Status on 03/06)
9
Weak insulation to ground on QTLD.412305: problem with one of the insulators brazed on the coil manifolds to be replaced. Still EPC qualified as acceptable the measured leak current and tests could be completed. ELQA Magnets, PC and WIC (Status on 03/06)
10
ELQA Weak insulation of circuit RBI.410147: some cooling flexible hoses with a weaker insulation to ground removed and resistance increased by x2 acceptable for EPC, tests could be continued Need new SW to complete the tests!! Magnets, PC and WIC (Status on 03/06)
11
Heat run off all “new” circuits but the MBG last night Tomorrow 07/06 (SPS and LHC TS): – Installation of BPM electronic cards (6:00-10:00 am) – MBSG heat run (10:00 – 17:30 am) – Start release of new SW for main switches Wednesday 08/06 (LHC TS): – Complete release of new SW for main switches within 11:00 am: 1.SW ok for EPC OP tests a.OK main dipoles ready for beam extraction towards AWAKE (mains heat run missing!! Need 24 hours of LHC TS) b.Not OK role back to old SW version not ready for extraction 2.SW for EPC not OK role back to old SW version not ready for extraction Latest Updates and Next Steps
12
First AWAKE Proton Beam Extraction in Week 24 Main requirement: new SW for main switches deployed and validated. Since heat run of main dipoles will not be performed the powering of the line will limited to maximum 2 hours. Without beam: Pulse full line and check correct triggering of magnets and diagnostics (logging and interlocks in parallel) With beam (pilots: 5e9): Extraction of AWAKE beam from the SPS to the upstream TED Beam to the end of the line: preliminary check of the optics and diagnostics (in particular new BPM electronics) discard or identify issues which could further delay proton beam commissioning after next TS Possibly rough alignment of laser mirror with respect to proton beam
