SPS Instrumentation tips, doc & tricks

MOPOS :

• Synoptic of Mopos analog acquisition
• Mopos calibration procedure & principle
• Mopos calibration diagram example
• Mopos coast
• Gate position : when it is too close to one turn (23.1 us), there are problems with the turn cynshronization. In such a situation the gate should be re-positioned !!

BLMS :

• BLM list for ring & lines [EXEL] (old version)
• BLM list for ring & lines, including LTI & CNGS

SEMS :

• Map of SEM grids (Front ends)
• List of North SEMs / crate - BDI channel order
• List of North SEMs / crate - logical machine order
• Figures on the SEM layouts in the North, including the target TBIU/D
  • Fig 1
  • Fig 2
  • Fig 3
  • Fig 4
  • Fig 5
  • Fig 6

TARGETS :

• Target calibrations (EXEL) from FF.
• Gain should be medium on T10 & low on all others for normal p OP.

Q-meter BOSC :

• hint/vint channel       : FET               324/325 (H/V)

• sbunch                     : MOPOS         318/317 (H/V)

• ions                         : coupler            331

• Qkicker calibration : at 100 GeV 1 kV corresponds to approx +- 0.5 mm.

Screens :

• In TZ, the event to trigger BTV IN/OUT is in F_TZ_TZ_EVENTCODES

SCRAPPER :

• Timing event that triggers the actions : 0x21A5 (-900 ms before beamin).

• It takes ~ 1500 ms to move by 30 mm (slow).

• For normal scrapping, the delay should correspond to the actual scrapping time : any travel time is taken into account.

• Special mode : use -999 in the first column to terminate a sequence.
