keyword=add delay to gates, see data nowI added 650 nsec delay to the gates for LHRS DAQ. See the
circuit in fig 1. This may not be optimal yet, but we need
something like this.
I had to add a discriminator after the delay, else the NIM/ECL
would not fire.
I also put two copies of the T1 into one of the TDCs and called
them (temporarily) a V1 channel. I see these hits (fig 2), so
this shows that the trigger + DAQ + software is working.
I noticed that from the Hall A Tools GUI the VDC HV is off and
the thresholds are off. Are we still controlling them this way ?
Turning those on would lead to better results on the VDCs ...
