Week 44 - Parallel MD (Monday through Friday 1-5/11/2010, from 8h00 to 18h00)
N.B. The parallel MDs take place all the time from 8:00 to 18:00, provided the LHC is in store or does not request beam. The MD cycle can be removed from the supercycle during the LHC filling
Monday - High intensity individual bunch studies in the SPS: longitudinal plane (measurements along the cycle and scan of the 800MHz phase)
Beam conditions: High intensity version of LHCINDIV on the LHCFAST_L7200_2009_V2 cycle (intensity range according to request)
PSB user = MDPSB
PS user = MDPS
SPS user = LHCFAST
RF MMI target = LHCMONO
Contact Person: T. Argyropoulos, C. Bhat, B. Salvant
Tuesday and Wednesday - Optics studies for the change of gamma-transition
Beam conditions and cycle: Single LHC-type bunch on MD_26_L7200_Q20_V1 for flat bottom studies, or LHCFAST_L7200_2010_Q20_V1 with acceleration. For optics measurements and corrections, 8 bunches of LHC75 half intensity could be requested from the injectors.
PSB user = LHCINDIV or MDPSB or LHC75 (only Riog 3, nominal or reduced intensity)
PS user = LHCINDIV or MDPS or LHC75
SPS user = MD1 (no acceleration) or LHCFAST3 (with acceleration)
RF MMI target = LHCMONO
Sequence = PSB.LHCINDIV.1_0->CPS.LHCINDIV.2_1->SPS.MD1.6_2
Contact Person: Y. Papaphilippou, H. Bartosik, et al.
Thursday - Friday - Studies with ions on a || 1 injection cycle
Beam conditions:
LEIR user = EARLY
PS user = LHCION
SPS user = LHCION1
RF MMI target = LHCION
Contact Person: T. Bohl, P. Baudrenghien, D. Manglunki
When possible in the PSB and PS, the MD cycle played in the SPS before the ion cycle can be used for some additional // MDs:
Thursday - Friday - High intensity individual bunch studies in the SPS on the MD cycle: longitudinal (scan of the 800MHz phase) and transverse (emittance growth)
Beam conditions: High intensity version of LHCINDIV on the MD_26_L7200_V1 or MD_26_L7200_Q20_V1 cycle (intensity range according to request)
PSB user = MDPSB
PS user = MDPS
SPS user = MD1
RF MMI target = LHCMONO
Contact Person: B. Salvant, T. Argyropoulos, H. Bartosik
PS (according to availability):
Monday - Friday (slots aimed for are Tuesday afternoon, Wednesday, Friday morning, total 16h) - Longitudinal coupled bunch instabilities in the PS
Beam conditions: 3bp LHC-type beam, with 7 nominal bunches injected from the PSB (instead of the usual 6)
PSB user = LHC25A+B (n.b. LHC25B is a modified version of the nominal one, it needs to have also Ring2 active to completely fill the 7 PS buckets)
PS user = LHC25
Contact People: H. Damerau
Thursday - Floating MD (10h) → canceled (postponed to Week 47)
