keyword=Cleaner Trigger Copies
observations and changes during todays access:
(R.M. , B.R.)
left arm:
copy of T1 on left arm scalers :
looks rather clean, at least much cleaner
than the original copy on the right arm.
( we didnt see any clear double pulses on the scope,
but it is hard to see them, if they apear only at
the percent level)
T3 on the left arm scalers:
looks also clean, but we found some.
(we saw 8 double pulses during 100 sec (approx 1000 Events,
but don't know about efficiency of the scope))
left arm scalers:
produced a "clean" copy of T3 (using a discriminator as gate
generator with approx 150 ns width)
connected it to channel 30 of the normalization scalers.
connected a copy of the EDTM pulser to channel 31 and 32
right arm:
connected a copy of the EDTM pulser to channel 30 and 31
of the right arm normalization scalers.
( here the "clean" copy of T1 was alread connected to channel 32 )
