Signal Processing
Discriminator
CAEN N841
The pulse forming stage of the discriminator produces an output pulse whose width is adjustable in a range from 5 ns to 40 ns. Each channel can work both in Updating and Non-Updating mode according to on-board jumpers position. The discriminator thresholds are individually settable in a range from -1 mV to -255 mV (1 mV step), via an 8-bit DAC. The minimum detectable signal is -5 mV. The back panel houses VETO and TEST inputs, the OR output and the Current Sum output, which generates a current proportional to the input multiplicity, i. e. to the number of channels over threshold, at a rate of -1.0 mA per hit (-50 mV per hit into a 50 Ohm load) ±20%.

Software
Ntuple maker
To make the Tree containing the TDC, QDC, and PDC data run the following command
source ~/CODA/setup
/home/daq/CODA/CODAreader/ROOT_V5.30/v775v792v785/evio2nt -fr8735.dat >/dev/null
rename the output file to a root file
mv r8735 r8735.root
root -l r8735.root
to draw a histogram for TDC channel 16
DAQ->Draw("evt.TDC[17]>>(4096,0,4096)");
