I was even more productive yesterday and assembled this cute stack!
It’s four Hamamatsu S1337-1010BR Si photodiodes with respective amplifiers. I want to add a scintillator, a light-proof metal casing and see whether I can use this as an energy-dispersive x-ray sensor, maybe even do energy-dispersive x-ray spectroscopy
@janamarie Very cool project! What kind of amplifier are you using? We have been thinking about a DIY EDX for our SEM for while now...

@stdlogicvector @janamarie I copied this design from muonpi.

(The description is wrong and needs updating, the latest version uses onsemi SiPMs)

It works well, I can see a nice finger spectrum.
