Alpha Calibration Runs (need to check settings in logbook)
0-63: dE detector and 32-47 is n+n; 64-127 E detector and 96-111 is n+n; 128-191 HI detector
Run 13: alpha source in fromt of dE detector (0-63). All detectors connected.
- 0-15 OK
- 16-31 OK
- 32-47 pulser appears at higher amplitude, alphas in a similar spot
- 48-63 OK
- 64-79 ch64 low gain but only for pulser (alphas look fine)
- 80-95 ch83 low gain, ch88 bad resolution. some strips show alphas
- 96-111 ch102 no alphas, ch103 low gain
- 112-127 pulser OK
- 128-191 (HI detector) looks ok
