My Homemade Structural Analysis X-Ray Machine

[Luca c.]

Hi everyone, I recently finished my third prototype of a structural analysis x-ray machine. It took almost 1 year to reach this stage, and this forum has been very helpful for his development because sometimes I got stuck with electronics. So thanks

This is the schematic I'm currently using, it consist of a 4 stage CW with negative polarity powered by a zvs, the negative polarity is due to the fact that I'm using a soviet bsv-29 structural analysis xray tube.
With this setup I have been able to perform successfully diffraction experiment, in particular I got some wonderful laue diffraction image:
Mica

NaCl

Menthol

This patterns were recorded on some autodeveloping dentist film, and are created by the interaction of the xray and the particular arrangement of the atoms inside the crystal structure.
The image took a lot of time, all more than 1 hour exposure, I think that is due to the fact that my system is running at around 270W, that power limitation I think is due to the flyback transformer core size, normally, in research laboratories (with machine that cost 150K$) these tubes are run at 2000W or more, so there they need less time.
I also tried to document some aspect of the development and tried to make a youtube video, if you would like to give it a look there it is:

/>Inside the video you can find other details of the construction and also of the chemistry that went into this experiment.
The future upgrade I would like to make is a second flyback transformer in parallel to increase the power and also a liquid system for the flyback primary coil, because it is heating way too much and very fast.
Also I would like to experiment with a H bridge to be able to fix the frequency of operation, because at the moment it is in the audible range and is so loud that staying in the room with it after some time become uncomfortable.
If you have additional question regarding the project or specific aspect of the build or the physics/chemistry behind all of this they are very welcome.
