CsI(Tl) and SiPMs?

[Cole W36]

Hello,
So this is my first project involving gamma spectroscopy and I want to build a SiPM based spectrometer that can read isotopes in the air as it flows by and then transmit the results to either my phone or a 433 MHz reciever in my room but I can't really find any details on such an idea.
Would it go CsI(Tl)-> SiPM->preamplifier->amplifier->ADC->MCU->DSP->transmitter?
I am using 3 × (9 by 9 by 30 mm) crystals supplied by Scionix by the way.

To simplify what i'm trying to do is I'm trying to figure out how to take 3 x MicroFC-60035's (and reduce crosstalk between them), and then amplify and shape the signals to a decent enough quality for detection by the ADC and then the processor (a Arduino UNO) to send it to either a screen or a bluetooth module.

Hi Cole?
I don't see a problem, if you simply separate the crystals and the sipm's by e.g. aluminum foil there is no crosstalk at all.

Please also note that you have to stretch the signal coming from the SIPM. Digitizing of the "pure" SIPM Signal would require a very fast ADC, which would result in a way to high data-rate for an Arduino Uno!
I recommend to stretch the signal to at least the level that is suitable for sound-card spectroscopy. That should be slow enough.

If you are interested in bluethoot, i recommend taking a look at the ESP-32 Modules, which also can run Arduino. They are much faster than the UNO too.
I could upload a schematic of a pulse stretcher and power supply if you are interested.
