Gamma Spectrometry Forum

The scintillation probe I am using runs on a positive supply voltage. The pulse I get is negative. The negative pulse is not a problem because I set my PRA height threshold to a negative number. I am curious, however, because it seems that most scintillator probes send a positive pulse (perhaps I am...

Thank you, Steven. I will try that procedure as soon as I can. Sorry about the introduction confusion; I had created a post in the Introductions section last week titled "Introduction and a few questions" posted 16 Jan 2017, so I thought that was taken care of. However, I just noticed that...

I've read many of the posts on this forum and I keep seeing references to a procedure but I can't seem to find any ...
