Task¶

The task at end is to continue to take data for the emittance reduction measurement with LiH, task H7.

The cooling channel is in the setting 2016-04_1.5 which, corresponds to the following field in the cooling channel:

Task H7 - Emittance Reduction!!¶

Task	Momentum	# Triggers	Beamline Tag	CoolingChannel Tag	Similar runs
H7a	140	1e6 TOF1	3-140+M3-Test2	2016-04-1.5	H4a
H7b	140	1e6 TOF1	6-140+M3-Test2	2016-04-1.5	H4b
H7c	140	2e6 TOF1	10-140+M3-Test3	2016-04-1.5	H4c

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

Task H7 - Emittance Reduction!!¶

Adding 240 MeV/c data.
