Re: Info about probe

Hi Luuk I ‘ve had no doubt you were the only guy that could gave me info.
3mm thickness : this is the reason I cannot obtain a spectrum of cs137!
The detector is working : it give good cps response also with weak sources.
But if the Crystal is so thin: what’ the center hole for?

Re: CSI Detector

Hi Nicola, The detector is exactly as Tom described it, 13mm round, 38mm long, the crystal is CsI(Tl), the pmt R7400u. It is difficult to connect them because the pmt wires are very fragile and it is hard to find the right pmt socket. If it works you expect a resolution from around 7.2-7.5%@662KeV ...

I made a detector with a CsI(Tl) 2”x2” crystal.
The results are really good and it is very simple and easy to do.
If you interested please read the attachment.

Re: Spectrum of Allanite-Ce

Hello,
The spectrum you obtained is typical from Thorium.
Is easy to find allanite samples associated to some Thorium minerals.
