Veto

steps to setup the veto:

  1. Choosing an input to the pulse generator with earliest pulse in time. (usually the gun)
  1. The output of the pulse generator should have a width that contains all the pulses that have to have Veto.
  1. delay so we one pulse remains.
  1. observing any change in the accelerator pulse frequency, since it will affect the delay of the pulse generator.

TDC

The main point of setting up the TDC is to observe the output of each channel (GEM or PMT) and determine the time period between each pulse the common start or common stop pulse. (TDC observe the pulses that occurs is 1100 ns before or after the trigger pulse.)






ADC is connected,

Beam On: run 5496 as the detector is on 13:31:11 13:47:18 run 5497 as the detector is off 13:52:51

5537 on 16:22:00 16:27:03
5541 on 16:42:02 16:27:03

All the previous runs has a positive input to the ADC.
