Some recent PS MDs

1
Some recent PS MDs

• LHC beam
• TOF (see Gabriel Metral talk)
• AD (see Roland Garoby talk)
• Optics _at_ 26 GeV/c
• PSB-PS matching
• Profilometer tests
• SPS-MDs preparation

2
LHC beam

• Single batch (4 bunches)
• preliminary studies of injection errors on
  various bunches / rings
• ax 1.5mm gt Dex 0.16 mm gt 8 of b.u.
• ay 3mm gt Dey 0.65 mm gt32 of b.u.
• Double batch (44 bunches)
• almost all HW modifications done
• ready (?) to start measurements with beam

3
Optics _at_ 26 GeV/c

• PS and TT2
• closed orbit minimisation gt done
• new matching for FTA(AD) line gtdone
• optic meas. With TT10 gt analysis in progress

4
PSB-PS matching

• New BTP transfer line optic
• Problems with
• Pow. Supplies controls
• Instrumentation (WS)
• coupling effects, etc.
• ...the new optic is better than (or at least 'as
  good' as) the old for emittance preservations of
  small emittance beams(A.Jansson dixit)
• a suivre (tests on high intensity beam, LHC beam,
  etc.)...
• Quadr. p.u. measurements
• in progress, (see next PPC)

5
New profilometer tests

• Test with beams at various energies
• 1.4, 3.5, 26 GeV
• other energies in preparation
• incompatible with ion beams (stripping by vacuum
  bump)
• tests will continue on last MD (before Xmas)

6
SPS-MDs preparation

• TSTLHC nominal LHC beam
• MDPROfast extr. _at_ 14GeV/c
• MESPSsingle bunch (long or short) _at_ 26GeV/c,
  various intensities
• MDSPS bunch train at 26GeV/c
• etc.
• in preparation single bunch _at_ 20 GeV/c
