IAC data analysis for GEM

03/26/15

Electronics Setup

PS-ADC, QDC and TDC were used for this experiment. The collected data for GEM was discriminated by CFD and its output was in coincidence with beam gun signal, which became an input for gate generator for QDC and PS-ADC and stop for the for the TDC. (TDC setup was in a common start and beam gun signal was the starter).

The picture above shows the time frame of the pulses relative to each other. The beam gun was earliest in time, then the beam electron's signal came after with after 200 ns, finally GEM's signal as it is in time with the stop pulse for the TDC.
