Description
The timing resolution of the photomultiplier tubes(PMTs) signals is measured with an accuracy of a few nanoseconds and depends on the PMT size, dynode configuration, applied HV, etc. In large-scale experiments, precise timing is crucial. However, prepulses and afterpulses can degrade the overall time response and trigger conditions of the experiment. We have studied the rate of prepulses and after pulses for PMTS (electron tubes, 9266QB) using an LED source. The UV PMT is used for the first time in our lab and wanted to study the noise rate of those and compare it with earlier PMT in the lab. The talk will present the rate, arrival time, pulse height of those PMTs at different applied voltages on the PMT circuit.
