Re: making out own scintillation crystals. Is it possible?

Yes, I thought this would be the reaction to my inquiry.
DIY scintillation crystals are a bit of a dream unless one has the perfect setup.

I wonder if anyone has given it a go? Makes me even more curious.


At least ZnS:Ag is completely doable at home for Alpha scintillation detectors.

making out own scintillation crystals. Is it possible?

I was reading some literature on the vertical Bridgman method of growing CeBr3, SrI2:Eu and LaBr3:Ce crystals and I got curious if we as hobbyists might be able to start growing our own scintillation crystals? There is a bit of literature on DIY bridgeman furnaces that looked promising. Any experien...

Re: Gamma spectacular + Red Pitaya = Nuclear Dragon fruit?

Attached is the spectrum from the RedPitaya in the attached files. I imported this .CSV file directly into InterSpec.... note that the Cs137 peak vector is off. should be ~6.5% FWHM not 7.33%. I am still learning how to use Interspec and had some issues with the way the vectors clamp onto the peaks....

Re: Gamma spectacular + Red Pitaya = Nuclear Dragon fruit?

I'm still contemplating doing a LaBr3:Ce homebuild with a bialkali PMT... It'll be interesting to see if the combination of the FPA and ADC can handle the short pulse widths without needing to be stretched out. This is a raw hack... there is no external pulse shaping with my NaI/Tl detector whatsoev...

Gamma spectacular + Red Pitaya = Nuclear Dragon fruit?

So, I have been on a quest to try and build an ARM based gamma spectrometer just for "fun"... it has been an involved process. (more on that later) While investigating my project, the RedPitaya 125-14 STEM LAB brand oscilloscopes stood out as a possible platform for experimentation. I noticed that 2...

Re: More fun with CeBr3

Too bad it is far out of reach to DIY a CeBr3 crystal from scratch. I'd really like to have one. Can't afford it though.

Re: Th232 spectrum from today 3hr sample time

Yes again, you are right.... I went back and had another look. I was a bit sloppy when I quickly read the histogram. I am going to try and convert the .CSV file so that Interspect can use it for post processing. Numbers doesn't give me the ability to finely tune my X-axis for energies. Lots of Ac228...
