3D X-ray setup

A real-time, fluoroscopic X-ray setup of my previous attempts with the beryllium-window tube. However, radiographed objects are now placed on a slow moving turntable motor, thus creating a spectacular 3D effect, captured on camera.… [read more]

8-stage Cockroft-Walton/Villard cascade multiplier

Something I’ve crafted for the new X-ray experiments: a half wave, eight stage Cockroft Walton multiplier (or a Villard cascade, whichever name you like), submerged in oil, providing a theoretical maximum output voltage in excess of 220 kV with a maximum supply voltage of 10 kV AC, with headroom.… [read more]

Fluoroscopy of a hand

This might be the craziest documented experiment/project on my page – a fluoroscopic radiograph of my hand, utilizing my beryllium-windowed vacuum tube setup. For the sake of your own safety and the safety of others, do not attempt to recreate without proper knowledge and protection, as hazards include radiation sickness, increased risk of cancer or amputation of irradiated… [read more]

Flyback driver #3: ZVS

The ZVS flyback driver, made popular by Vladimiro Mazzilli, is one of the most efficient and powerful flyback drivers used by high voltage hobbyists from all over the world. The main advantages of this driver are simplicity of the circuit itself, very high efficiency and easily obtainable parts. By tuning it properly you are able to get insane power outputs; beefy flyback transformers… [read more]

X-rays with a Beryllium-window tube

While lurking on eBay on a nice spring day of 2012,  I have been lucky to obtain a real gem, for a very cheap price indeed: a special micro-focus X-ray tube, with a Be window on the beam port, mostly for spectral analysis or fluoroscopic scanning purposes, for up to 150 kilovolts with forced oil cooling at high powers; made by a now-defunct American EG&G Astrophysics company… [read more]

X-rays with a dental Chirana

After receiving a donation of two nice X-ray intensifying screens from Mr. Máca, a Czech radiologist (many thanks!) in 2011, it wasn’t long before I got a hand on a real X-ray tube, obtained through barter trade, with some luck, too. Only then were my previous failed X-ray attempts with DY86‘s and 6VS-1‘s marked with success, at least!… [read more]
