Re: Info about probe

Of course... The model number gave me all sorts of information about its configuration.
A user here named Luuk used to work for Harshaw, and now Scionix Holland. He may know more about the detector and its design use.

Re: Info about probe

Nice find, an odd one for sure. It appears to be a 3" diameter NaI(Tl) crystal with WELL in center and probably a 1-1/8" PMT (maybe a Hamamatsu R6095 or similar) attached to the side of the crystal (D style coupling with a section of rounded part of the crystal flattened for PMT attachment). Of cour...

Re: Tin, and Pewter, and Copper, and Iron, Oh MY!

Why not just order the TIN sheet from my reference above... The vendor told me it is pure tin, not alloy or pewter, although they use "pewter" as a search word in their listing.

I usually order from a seller called greenstuffworld, their tin sheet found here... https://www.ebay.com/itm/282104195838

Re: Very Large Anti Compton system

Luuk - You guys at Scionix Holland always impress me, but this time I'm blown away by the build. I'm sure nerves are on edge while building such a delicate and expensive detector, but WHAT FUN & SATISFACTION you and Tom must have when it's all done and report to Paul your success!!! Cheers, Tom
