Results
  PGC 78 and sector 12 SIM_VS   Week 24    
  Beam Dump IV Beam 1:
- BETS and BEM tables online check
- Circulate & Dump
- Inject & Dump : measure time response (dump on the first turn)
- XPOC: BSRA analysis, GUI also showing exceptions, (reference management?)
- BPMSA Acquisition		 12-13 June    
  Injection and Transder IV

- LHC mastership, injection requests...with scrubbing beam in the SPS
- Injection permits to MKIs
- BETS at the injection kickers (check for different energies from LBDS BETSsim
- Injection BI + concentrators

 11 June    
  CMS send data from the pit to LHC using DIP

Data transfer

 11-14 June    
Done LHCb Dipole - polority changes & de-Gauss 6 June   Done [Reyes] - looks good
Done ALICE dipole and compensators   6 June - PM after cooling back on to compensators   All 4 ramp to 7 TeV - both polarities
Done Beam Dump IV  
Week 19
Planning
Both beam dump systems connected to the (local) BIS;
Done

PGCs in sector 56
Cold sector test 56

Sequencer - week 19
  • Full magnetic sector: transfer functions, harmonics
  • Full LSA deployment: parameters, settings, trims, incorporation
  • Hit all available circuits
Week 19
Planning
Done Injection and Transfer III
  • RF pre-pulses to LHC injection kickers
  • Injection requests to CBCM - test injector response
Week 19
Planning
RF pre-pulses at the injection kickers; RF rev. frequency from point 4; abort gap keeper at the injection kickers; injetion permit at MKI 8; injection request to the injectors working (with the right pre-pulses generated and the right kickers pulsing and the correct number of patches requested from the PS and pre-pulse shifted according to the chosen bucket); critical settings checks working for MKIs, MKDs and MKBs;
Done Beam Dump III
Injection & transfer II		  
Week 15
Planning
Results
Done Cold sector test 45
[with AB/PO]
  • Full magnetic sector: transfer functions, harmonics
  • Full LSA deployment: parameters, settings, trims, incorporation
  • Hit all available circuits

1. Ramp of QF/QD/RB + most other circuits in sector 45 to > 5 TeV level.
2. Squeeze of 5L at 7 TeV level.
138/183 circuits to 5.3 TeV
           
Done Magnetic Sector I Whole sector in VS, full pre-cycle, injection plus FIDEL, ramp inc bumps & snapback etc.
March - pre 56 PGC
OK - subsequently PGC in 45 in good shape
Done Beam Dump II  
Week 11
Results
Done Beam Dump
  • Interfaces to LBDS
