keyword=profile scanner checkoutSince the profile scanner scintillator was allegedly fixed, we
will do a few short runs to check versus VDCs.
Run 2187:
On both arms, X = 15, Y = 34 cm
Turn on HV for scint. at -1800 V
See T5 = 16.8 Hz and T6 = 15 Hz
Run 2188:
Remains in same X,Y location. ADC spectra looked low on R-arm.
Increase HV on scint: L-arm to 1850 and R-arm to 1900.
Notice the T5,T6 rates don't change much.
Run 2189
X = 18, Y = 30
Run 2190
X = 15, Y = 28
Fig 1 shows the ADC spectra for T5 & T6 for run 2188.
Not much amplitude in the R-arm. But then we got something
for run 2189 -- fig 2. There's an X-Y spot too which I'll show
shortly.
