Scionix Harshaw probe type 51A10: Does it fit to GS-1100 PRO?

Post by Springdream » 15 Nov 2017, 20:40

Hello together,
I am wondering if anyone knows if the Sionix Harshaw 51A10/2M-EJ228-E1-XN probe can be conected directly to the GS-1100 PRO.
And I'd also would like to know some technical data, e.g. the dimensions of the NaI crystal. Diameter is 2", but lenght? There were also probes with very thin crystals on the market that are not really suited for gamma spectroscopy. It is almost nothing available on the web...

Reason why I am asking is that it has obviously a separate signal & HV socket.
On the Therminio board I found some information that this kind of sensor but without a link to a probe type. Therminio MCA does only have a combined HV+signal port, so it is really important there. But I don't know if it is relevant with the GS-1100 PRO.

Thanks for any feedback,
Martin

[SOLVED]: I got a response from Scionix that it is a Plastic scintillator => not suited for gamma spectroscopy and no reason to further think about it...

Here is a link to Scionix numbering scheme:

(I am not related to Scionix, just for information because hard to find in the internet)

Good catch on it being a plastic scintillator. I nearly bought one myself. I do own a 2 inch WB Johnson plastic scintillator, but I use it with my survey meter for prospecting in the field and "urban" prospecting at antique shops and thrift stores. The cost makes them hard to pass up.
