Cosmic Coincidences
setup
Setup a cosmic coincidence experiment with two crossed scintillators that have the proto-type drift chambers sandwhiched between them.
Built 4 100 ns long delay cables. 2 for the PMTs and one for sense wire 7 on each of the drift chambers.
The top PMT is in channel 7 of the QDC and channel 16 of the scaler.
The Bottom PMT is on channel 8 of the QDC and channel 7 of the scaler.
Coincidence counts are recorded in channel 2 of the scaler.
Runs
Run 182: Ran with coincidence module in "OR" mode so if either paddle triggered the ADC was read out
Run 183: Switched coincidence module to "AND" mode and ran overnight.
