Re: wfd

Hi Peter,
I just wanted to confirm my understanding of the wfd channel
count. You have 4x14=60 channels instrumenting 60 of 64
gondola channels and need one additional wfd module to complete
this set-up. Also how many neutron counters are currently installed?
At present are simple TDC and ADC signals being recorded
for neutron triggers (and pre-scaled e/g triggers?).
Cheers, Tim.
