In summary, the conversation discusses collecting photomultiplier tube (PMT) tube data and the best way to analyze it. The person asking the questions is interested in getting the relative total intensity and other statistical analysis. Another person suggests using a correlation detector and mentions that a PMT may not always be the best choice. The conversation also briefly mentions using synchronous detection with a modulated source for remission signals and asks for more information on the apparatus being used. The original question is about the analysis of various aspects of the PMT data, such as leading edge, gain, quantum efficiency, and dark current.

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?

He's been gone for almost a year.

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