Photopeaking a Scintillator Detector: What Is It?

[rawlstom]

What is meant by "photopeaking" a scintillator detector?

 

[ChrisVer]

maybe when photons deposit their whole energy in the detector (are absorbed)?

 

[rawlstom]

It has something to do with calibration of a scintillator.

 

[ChrisVer]

probably, since you can use the peaks of let's say known elements to calibrate the detector response?

 

[rawlstom]

So, it is when you check the machine against a known source?

 

[ChrisVer]

check eg https://en.wikipedia.org/wiki/Gamma_spectroscopy#Sodium_iodide-based_detectors
You are using the known peaks for calibration sometimes... [if not always]
