Week 38 - Floating Injector MD 

(From Thursday 23/09 at 08:00 to Friday 24/09 at 00:00 in // to LHC, total duration 16 hours)


The starting time of this MD as well as the actual number of MD hours depend on the beam request and filling of LHC

- Thursday 08:00 - Thursday 18:00 => Tests with the 4 injection I-LHC cycle (16.8 s)

Beam conditions: 4 early ion bunches injected into the SPS

- LEIR user = EARLY

- PS user = LHCION

- SPS user = LHCION2

- RF MMI target = LHCION

Contact people: T. Bohl, P. Baudrenghien, D. Manglunki

 

- Thursday 18:00 - Thursday 19:00  =>  Set up of the supercycle coastable at either 55 or 270 GeV/c. The cycle name is MD_25.92_55_270_2009_V1

Beam conditions: 12 bunches of LHC 25ns beam at half intensity (5e10 ppb)

- PSB user = LHC25A (Ring 3, half intensity archive)

- PS user = LHC25

- SPS user = LHCMD1 (in pulsed mode), COAST1 (in coasting mode)

- RF MMI target = LHC25NS

- Timing sequence = LHCMD2 0/1/2 (Coastable 55-270 GeV)

Contact people: BE/OP, BE/RF

 

- Thursday 19:00 - Friday 00:00  =>  SPS studies in view of an installation of a KEK-B crab cavity in the SPS

Beam conditions: as above

- PSB user = LHC25A (Ring 3, half intensity archive)

- PS user = LHC25

- SPS user = LHCMD1 (in pulsed mode), COAST1 (in coasting mode)

- RF MMI target = LHC25NS

- Timing sequence = LHCMD2 0/1/2 (Coastable 55-270 GeV)

Contact people: E. Métral, R. Calaga, F. Zimmermann

 

- Friday 00:00 - Friday 01:00  =>  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

Contact people: BE/OP
