Congrats on your XRF detector! It is certainly convenient to just leave the front scintillator surface exposed to air, thus allowing it to easily detect lower energies (under 12-15 keV). However, the CsI:Ti scintillators are still considered mildly hygroscopic, hence typically requiring encapsulation which will then ruin the ability to detect lower energies unless the front window is made from beryllium...
Great video, great results! Perhaps you can include some links in the video description to the version of the Theremino S/W you used and also the PMT interface circuit? The Theremino site is a nightmare to navigate...
much can be said about the youtube algorithm, but it brought me here, so i am grateful. subscribed! greetings from alaska!
Sometimes it brings people to strange places, don't forget to check out the other strange video here. stay warm up there

I wanted beryllium for my detector so bad😵🥲 if only I had been born 50 years ago

@project-326 hi, thanks. Yes, I can relate to that problem, so I added two links. You need to scroll down a bit to reach the schematics
