content: I'm looking for a few things, in no particular order:Complete x-ray heads- any that can be powered with relative ease.Microfocus tubes or complete heads. Something smaller than the generic 0.5 to 0.3mm spots.High voltage supplies. The sweet spot is ~70-105kV @ 0.5-5mA, but lower or higher is also fine.Working digital detectors. Anything functional, from a tiny size 0 dental sensor to 30x40cm full digital plates.Acquired!I also have for sale, or preferably trade, a brand new 75kV x-ray tube - a CEI OX/70-g4. It's never been powered up, including the filament.Any offers are welcome, either via replies or in PM/email(preferred) - eevblogwtb@spirit.re

content: Bump!A large x-ray detector is in the mail.The new priority is high voltage supplies. If you have anything that can output at least 70kV(or -70, that'd be better) at 200uA or higher, please let me know!

content: I've decided to list one of my x-ray tubes for sale, or preferably trade - a 75kV, 0.4mm focal spot CEI OX/70-g4. It's new, never used.Still looking for other x-ray tubes, x-ray heads, or high voltage power supplies.

content: I have a Hamamatsu C9732DT. A 12cm square 5.5MP CMOS sensor. Not much info on the "DT" version, but all the relevant specs are almost identical to the "DK" version. No idea what the K and T mean.Works very well, but the pucker-factor on dropping something so expensive is very high!Quote from: artelse on July 24, 2019, 11:00:11 pmA digital image sensor will NOT work for testing leakage. In fact, if you're even a little unsure about leakage in a DIY setup, you really should reconsider doing things.Otherwise, what you need is a thin-windowthin-crystallow energy gamma/x-ray scintillator for detecting leaks. They're rather rare, but I did manage to score a Bicron Analyst with a G1LE probe a while ago, which is the kind of probe you'd want.A regular scintillator probe, even with a thin aluminium or mylar windowwill not workfor proper x-ray detection, due to how different crystal thicknesses respond to energy spectra. A thick spectroscopy or survey crystal will be almost blind or on the level of a GM tube at x-ray tube photon energies.

content: Water chillers are pretty much worthless, unless required. Definitely worthless to me, I'm afraid.
