IN addition to this, channels 62, 63, 64 of the raw T scalers are
fed with the following signals:
62 PC
63 PS
64 TAC
Some signals are also brought upstairs in the couting room]
(for timing check):
Trigger:
PC before the coincidence module
TAC before the coincidence module
ST before the coincidence module
MOR before the coincidence module
WARNING : DANGER : THOSE SIGNAL ARE TAKEN FROM THE ECL/NIM/ECL
TRANSLATOR THAT GOES TO THE TRGS SCALERS, IF THERE ARE NOT USED
AND NOT TERMINATED IN THE COUNTING ROOM, THERE WILL BE
A REFLECTION BACK TO THIS (WEAK) MODULE AND THERE WILL
BE DOUBLE PULSING IN THE SCALER.
SO: WHEN NOT USING THE SIGNAL IN THE COUNTING ROOM, TERMINATE
THEM WITH 50 OHMS !!!!
scalers:
one T as it enters the DSD.T discriminator
PC as it enters the DSD.T discriminator (minus a few ns of ecl ribbon)
PS as it enters the DSD.T discriminator (minus a few ns of ecl ribbon)
TAC as it enters the DSD.T discriminator (minus a few ns of ecl ribbon)
Others:
Busy signal from trigger
analog signal of the TAC sum
let's have a wonderfull commissioning
