Thanks tho Dan Scherer for contributing this ware! I don’t have a specific make/model number for it, but a general idea of what it’s for, so I’ll try my best to judge the submissions given partial information.

Dang, Matt beat me to it, but yeah, looks like the power supply from a sealed X-Ray generator unit from something like a baggage scanner. Normally fully submerged in oil, I think both for cooling and insulation, in a heavy lead-lined box. Looks somewhat similar to the one in this video: https://www.youtube.com/watch?v=Q4ffx5eX39E – only differences are the lack of a tube, and a missing second voltage multiplier.
Yeah, it would almost have to be immersed in oil. The flyback transformer secondaries are probably good for at least 25-30KV each, but the wires connected to them don’t have enough insulation for more than a few kV in open air.
Looks very similar to the power supply Mikes electric stuff pulled out of the x-ray generator from a baggage x-ray machine. Different though because it appears to be unipolar, with only one voltage multiplier. Suggests it is lower voltage than the 150kv from the baggage machine. https://youtu.be/Q4ffx5eX39E, you can see the internals at 4:15 or so. Looks like the pieces of pcb material are identical, and so is the potted voltage multiplier box. Transformers are slightly different though.
looks like a pretty clearly HV driver of some sort. The transformers remind of of various electrostatic generators. Both the industrial test variety, as well as tesla coils.
The obvious bits are the HV supply. My suspecion about the black box is that this is some sort of sensor.
It doesn’t have any optical openings. So it must be for some harder radiaton (No photo-multiplier unless with scintilator element)
The sense line does not quite fit into my picture. I have never seen a geiger probe with it’s own sense circuit.
I’m going to say it’s a high voltage supply for your SEM unit.
Looks like it is generating multiple voltages judging by the multiple transformers and voltage multipliers. Most SEMs I have seen have all of the high voltage PSUs crammed into one oil filled box.
What part of the SEM is hard to say since everything in the column is high voltage.(E-beam, condenser lenses, objective lens, eletro-static deflection, light pipe cage, scintillator surface, PMT)
The red box bottom left is a big capacitor (WIMA), there appears to be an AC->DC bridge on the right and the black box has 3623o (as far as I can tell). It’s mounted on a clear, plastic and at the top-left, you can see an unsheathed wire – safety for the box. As everyone says, looks by the thickness of wire to size of capacitor that high voltage without a high ampage.
From school (some decades ago), the black box reminds me of the lasers we had then.
Wild guess – Nitrogen laser. After all, we can’t see 3 of the 6 faces of the box.
High voltage supply for driving an X-Ray tube

yes great catch – even the wire colours match …..

Agreed, nice catch! I had seen that video a while back but would have never made the connection.

Redneck Geiger counter.

Degausser?

It is obviously a HV driver. My guess would be to drive an electron microscope beam.
