Re: Greeting from Canada... HELP!

Raphael I believe that seller does not rework the voltage divider values for that listing. It is a lot of work to rework it, and the listing would probably clearly indicate that if it were the case (as I clearly do in my listings for this detector). Just simply changing out the wires and coupling th...

Re: Greeting from Canada... HELP!

Hi Raphael, The Scionix 38B57 can be a very good detector, however it MUST be reworked in order to operate correctly with GS and Theremino HV Bias Drivers. Has your voltage divider been reworked? If so, what is the total value of the divider now? Was the detector tested before and after rework of th...

Re: CSI Detector

Here is what wiring the small TO-8 PMTs socket is like... I wired this one for most efficient power use. Notice in the pictures it now runs well at only 650 volts.

Re: CSI Detector

These Scionix CsI detectors are nice for their small size, however they use one of the more difficult sockets to find and/or wire a voltage divider for. Wiring directly to the very fragile pins is possible, but risk to the PMT is great and is not advised.

Re: CSI Detector

Based on the model number "13B38/0.3-CS-X", it appears to be a (X) customer custom 13mm diameter by 38mm long CsI (probably Tl) crystal canned together with a TO-8 Metal Package PMT (probably a R5600 or R7400). The pins are very tiny and fragile.

I'm sure Luuk could tell you more about it.

Hi Bob - I’ve seen you videos, great work. I especially love the work you did restoring that PRI 118 Royal Scintillator. What a beautiful instrument. Glad you are here. Cheers, Tom

GS-USB-PRO Review – Professional quality in every way!

I have used just about every sound card MCA driver out there, and made quite a few of my own as well, so I think my judgment of Steven’s new GS-USB-PRO is reasonably sound. In my opinion, the GS-USB-PRO is by far the best sound card MCA bias adapter on the market. From the moment I opened the box I ...
