keyword=Alignment with UMass detAlignment of the UMass detector.
dP = -1 % = 1.0895 GeV
Rates at 0.1 uA
T1 = 825 kHz
T2 = 140 kHz
T3 = 294 kHz
T4 = 165 kHz
T5 = T6 = 0
T7 = T8 = 56 Hz (S2 HV is off)
Observe that both PMTs on both arms have good rate, so
the UMass detector is working. HV was 1200 V.
Run 3139 at dP = -1 %.
Fig 1 -- momentum spectra for det1 and det3 above a cut.
So we find we need these momenta
P0L = 1.095
P0R = 1.097
