Week 42 - Long Injector MD
(From Tuesday 19/10 at 08:00 to Friday 22/10 at 18:00, last part could be in // to LHC)
LHC stops from Tuesday morning until Friday afternoon
- Tuesday 08:00 - Wednesday 07:00 => SPS upgrade studies
Beam conditions: LHC-type beams with 50ns (LHC_4Inj_FB7260_FT_835_2010_V1.csv, 15bp) and 25ns spacing (LHC_4Inj_FB10860_FT835_2010_V1.csv, 18bp)
First part of the MD:
- PSB user = LHC50
- PS user = LHC50
- SPS user = LHC4
- RF MMI target = LHC25NS
- Timing sequence in the CBCM = LHC1-0/1/2(1)
Second part of the MD:
- PSB user = LHC25A+B
- PS user = LHC25
- SPS user = LHC1
- RF MMI target = LHC25NS
- Timing sequence in the CBCM = LHC1-0/1/3(1)
Contact people: E. Shaposhnikova, T. Bohl, SPS Upgrade WG
- Wednesday 07:00 - Wednesday 08:00 => Supercycle change to LHC_ION_15inj_FT2306_450_2010_V1 (for 15 ion injections, 36 bp)
Contact people: BE/OP, BE/RF
- Wednesday 08:00 - Wednesday 18:00 => Tests with the 15 injection I-LHC cycle
Beam conditions: 11 ion bunches will be injected into the SPS, because of a hardware limitation to 24 cycles per beam in the central timing
- LEIR user = EARLY
- PS user = LHCION
- SPS user = LHCION
- RF MMI target = LHCION2
Contact people: T. Bohl, P. Baudrenghien, D. Manglunki
- Wednesday 18:00 - Wednesday 19:00 => Supercycle change to MD_26_120_18000_2009_V1.csv (coastable at 120 GeV/c, 15 bp, some references can be found at https://ab-mgt-md-users.web.cern.ch/ab-mgt-md-users/2009/MDCycles/SomeReferencesForpCoastAt120GeV/Ref.htm).
Contact people: S. Cettour-Cave, BE/OP, BE/RF
Beam conditions: 12 bunches of LHC 25ns beam at half intensity (5e10 ppb)
- PSB user = LHC25A (only Ring 3, half intensity archive)
- PS user = LHC25
- SPS user = LHCMD1
- RF MMI target = LHC25NS
- Timing sequence = LHCMD2 0/1/3
For the coast, mask the following SIS interlocks: KICKERS_SPSRING (essentially for the MKD_EARLY_ENABLED), switch off the MDSH119 (otherwise it will trip), POWER_CONVERTERS_TT10 (as some could trip during the coast) and BLRING_DUMP_CHANNEL_VETO.
- Wednesday 19:00 - Wednesday 23:30 => SPS studies in view of an installation of a KEK-B crab cavity in the SPS (emittance growth over coasts). Same beam condition, cycle and users as above.
Contact people: O. Dominguez, L. Ficcadenti, R. Tomás, J. Tuckmantel, F. Zimmermann
- Wednesday 23:30 - Thursday 00:00 => Change to the supercycle coastable at either 55 or 270 GeV/c. The cycle name is MD_25.92_55_270_2009_V1, 26 bp

- RF MMI target = LHC25NS
- Timing sequence = LHCMD2 0/1/3
- Thursday 00:00 - Thursday 05:00 => BBLR studies. Same beam condition, cycle and users as above
Contact people: O. Dominguez, J-P. Koutchouk, G. Sterbini, F. Zimmermann
- Thursday 05:00 - Thursday 08:00 => Cool-down

- Thursday 21:00 - Friday 17:00 => UA9
Contact person: W. Scandale + UA9 collaboration
Linac2:
- Wednesday 10:00 - Wednesday 11:00 - Test of the new Linac2 SISWatchdog
Contact person: R. Scrivens
PS:
- Friday 09:00 - Friday 17:00 - Validation of coherent injection oscillations measurement + correction of the 2nd batch with YASP
Beam conditions and cycle: LHC25 beam with double batch injection
PSB user = LHC25A+B
PS user = LHC25
Contact person: M. Gourber-Pace
- Friday 17:00 - Friday 18:00 => Recovery from MD, switch back to physics
- Change of supercycle
- Send beam to physics at the earliest time after set up of the physics beams
