- Detector voltage is 2750, 2650V GEM and Cathode successively. GEM QDC channel is CH5, TDC inputs: GEM is CH27, and scint. CH29. GEM gate width is 1.78 us, and TDC hits are all within 2um as shown in the picture.
QDC input was amplified using ORTEC filter amplifier with the following settings: x1, fine is 4, integration 500 and diff. 50 ns.
