  1. Event $A0 is generated by beam enable/pulse shifter beam status output (50 Ás delay).
  2. Event $AC has jitter problems when 720 Hz event is enabled.
    Debuncher is using $AE for its reference.
  3. Event $AD is armed by event $AA, delayed 100 Ás, and triggered by event $AF.
    (to remove HEP/Studies clock event jitter relative to beam)
