I did some TDC ring tests on Detector 4 by adding a 50 Ohm pass through terminator on the base of the top detector and another pass through terminator at the exit of the patch pannel
I needed recommission the DAQ TDC logic which seems to have become unplugged.
I added connectors so TDC1190[6] would have two hits separated by 400 ns
replay the data on daq2 with the command
CODA/CODAreader/ROOT_V5.30/R1DC/evio2nt -fr4516.dat > /dev/null
R1DC->Draw("(evt.TDC1190[1][3])");
R1DC->Draw("(evt.TDC1190[1][6]-evt.TDC1190[2][6])/10>>(4096,-4096,4096));
Both PMT HV were set to 1100 volts and the LED threshold was at 20 mV
run 4518 terminstors in
Run 4518 had the bottom PMT of Detector 4 as the trigger and the terminators in.
The TOP PMT did not have mutliple peaks
R1DC->Draw("(evt.TDC1190[1][3]-evt.TDC1190[2][3])/10>>(4096,-4096,4096)");
R1DC->Draw("(evt.TDC1190[1][2]-evt.TDC1190[2][2])/10>>(4096,-4096,4096)"
run 4519 terminstors out
Run 4519 had the bottom PMT of Detector 4 as the trigger and the terminators out.
The TOP PMT DID have mutliple peaks
