Nice apparatus! A side possibility; you can get single crystal silicon wafers super cheap (even select from the company what plane it was cut - 001, 011 etc.). Set it at the correct angle relative to your camera (maybe a micrometer rotation mount) and use it to get specific energies from the electron x-rays. The wafer need not be in the vacuum just line of sight to the x-ray source. Closer, of course, the better.

A side thought: one could "focus' the x-rays by placing the wafer on a circular vacuum ring and apply a moderate vacuum to deform the wafer into a spherical surface. This will weakly focus grazing x-rays off its front surface to "image" the source and provide an energy spectrum.

I'm planning to do something similar for energy. I have some CZT detectors which I'll mount on an x-y drive to position over the part of the image that I want to probe the energy at.

Some upgrades to the x-ray camera now include:
Diffrent molybdenum pinhole sizes 1.5mm, 1.0mm, 0.5mm to sharpen the image A 3D printed sensor holder to allow zooming in by varying the distance from the sensor to the pinhole Picture taken with a 1.5mm pinhole for 30s: Picture taken with a 1.0mm pinhole for 30s: Picture taken with a 0.5mm pinhole for 60s: Picture taken with a 0.5mm pinhole for 60s (brightened): Reducing the pinhole size noticeably sharpens the image at the expense of intensity.

New upgrades on the Mark 3:

New more compact cooling system using 3d-printed components and including more compact coolant pressure and flow measurements New grid assembly with 3d printed insulator box to allow a more compact design:

Very nice work. We all like to catch up on making out material better or better mounted for control purposes.

Beyond good - extremely professional. What is your ultimate objective for measuring the x-ray energies from a fusor?
