B How best to statistically analyse a PMT signal?

TL;DR Summary

I am looking for advice on statistical analysis of a PMT signal

Hello,

I have recently started collecting photomultiplier tube (PMT) tube data, and I'm curious how best to analyse it (attached right). I also have a background capture (attached left). I am looking to get the relative total intensity and any other statistical analysis I could make. Is anyone familiar with such a signal?

Thanks for any advice.

I think you could apply the two signals to a correlation detector.

I don't know what this is but will look into it, many thanks.

Maybe you want to reveal to us what this is all about ? What is your PMT looking at ? A scintillator, a spectrometer, something else ?

If you are supplying the light (i.e this is a remission signal) the most common method is some form of synchronous detection with a modulated source. Not identical to background subtraction for instrumentation reasons. Also sometimes a PMT is not the best choice. What is the apparatus?

My question would be "analysis of what?" Leading edge? Gain? Quantum efficiency? Dark current? The list goes on...
