Task

The task at end is to continue to take data for the emittance reduction measurement with LiH and also magnet alignment data. The H6 task is a diffuser study.

The cooling channel is in the setting 2016-04_1.2 which, corresponds to the following field in the cooling channel:

The following settings are to be taken:

Analysis

  • Tag is the beamline tag
  • Runs is a list of runs considered to make following calculations (I didn't use all runs for a particular tag)
  • TOF1 Triggers is the sum of the CDB TOF1 triggers scalar; note this is trigger requests (does not include dead time/etc)
  • TOF2 Triggers is the sum of the CDB TOF2 triggers scalar; note this is trigger requests (does not include coincidence with TOF1/etc)
  • lmc1234 sum is the sum of the CDB luminosity monitor scalar
  • time taken is the sum of the times listed (time between "start run" and "stop run")
  • number in muon peak is the number reporting tof01 in the muon peak, tuned by tag (roughly 28 to 32 ns)
  • number at tof2 is the number reporting at least one space point in tof1 and exactly one space point in tof2
  • number passing all cuts is the number passing:-
    • exactly one track in TKU
    • tof01 in the muon peak (tuned by tag)
    • TKU total momentum between 135 and 145 MeV/c
    • Exactly one space point in TOF0 and TOF1
  • number passing all cuts/p in tku:- I histogram p in TKU, then find the peak bin, then report number in the peak bin divide bin width
  • number passing all cuts/tof01:- as per previous entry, but this time using tof01 histogram
