To analyze photomultiplier tube (PMT) signals effectively, one should consider using correlation detection methods, especially if dealing with remission signals from a modulated light source. Understanding the specific application of the PMT, such as whether it is measuring scintillation or spectrometry, is crucial for selecting the appropriate analysis technique. Key factors to analyze include leading edge timing, gain, quantum efficiency, and dark current. It is important to clarify the type of data being collected to tailor the statistical analysis effectively. Properly identifying the apparatus and its purpose will enhance the analysis of PMT data.

TL;DR
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...
 

Thread 'Please Explain (actually explain) The Monty Hall Problem'

Hello, I'm joining this forum to ask two questions which have nagged me for some time. They both are presumed obvious, yet don't make sense to me. Nobody will explain their positions, which is...uh...aka science. I also have a thread for the other question. But this one involves probability, known as the Monty Hall Problem. Please see any number of YouTube videos on this for an explanation, I'll leave it to them to explain it. I question the predicate of all those who answer this...

Thread 'A variant of the Monty Hall problem'

There is a nice little variation of the problem. The host says, after you have chosen the door, that you can change your guess, but to sweeten the deal, he says you can choose the two other doors, if you wish. This proposition is a no brainer, however before you are quick enough to accept it, the host opens one of the two doors and it is empty. In this version you really want to change your pick, but at the same time ask yourself is the host impartial and does that change anything. The host...

Thread 'Value of intuitionistic logic'

I'm taking a look at intuitionistic propositional logic (IPL). Basically it exclude Double Negation Elimination (DNE) from the set of axiom schemas replacing it with Ex falso quodlibet: ⊥ → p for any proposition p (including both atomic and composite propositions). In IPL, for instance, the Law of Excluded Middle (LEM) p ∨ ¬p is no longer a theorem. My question: aside from the logic formal perspective, is IPL supposed to model/address some specific "kind of world" ? Thanks.
