Introduction: X-ray Generator Contest Video

About: Maker, Engineer, Geek Girl.

DISCLAIMER!!!: This project can be EXTREMELY dangerous if you do not know what you are doing, in the case of this system, the x-rays are the least of the problem, however a flyback transformer can give you a nasty shock that could even kill you in some cases. The X-ray emissions from this project are not dangerous if you understand the physics of how x-rays are produced and what type they are. Regardless, use shielding. I am NOT responsible for any damages to people or property if you attempt this.

Now that that's aside,this is a video demonstrating my X-ray source that works quite well. It uses a high voltage triode driven by a flyback transformer driven by a traditional Mazilli ZVS circuit. You can see the schematic I used here The ZVS or zero voltage switching circuit is used to drive a flyback transformer from a television set, which the accelerates electrons inside of the triode. The electrons slam against the metal plate and release their energy in the form of an x-ray. It is not a point source, so don't expect to x-ray your friends. This project was built with the intention of producing x-rays with components I already had or wanted to build. This device fulfills its operating requirements as I do not need a high energy point source at the moment. Eventually I will buy a real x-ray tube and test it on this setup. This complete setup will be used in part with an x-ray intensifier and fluorescence spectrometer to measure light output from the screen.
