SUMMARY

Photopeaking a scintillator detector refers to the process of calibrating the detector by using known energy peaks from specific radioactive sources. This calibration ensures that the detector accurately measures the energy deposited by photons, which is crucial for applications in gamma spectroscopy. The discussion emphasizes the importance of using known elements to establish a reliable response from the scintillator detector, particularly in sodium iodide-based detectors.

PREREQUISITES
  • Understanding of scintillator detectors and their operation
  • Familiarity with gamma spectroscopy techniques
  • Knowledge of calibration processes in radiation detection
  • Basic principles of photon energy absorption

What is meant by "photopeaking" a scintillator detector?
 
Physics news on Phys.org
maybe when photons deposit their whole energy in the detector (are absorbed)?
 
It has something to do with calibration of a scintillator.
 
probably, since you can use the peaks of let's say known elements to calibrate the detector response?
 
So, it is when you check the machine against a known source?
 
Thank you for helping me
