X-RAYS ARE EXCEEDINGLY DANGEROUS!
Whilst I will not encourage anyone to build and operate an x-ray machine, there are people in the world who will (I am one of them). The guides presented here for those people, to point them in the right direction, and prevent them from making serious mistakes.
The guides are written with the assumption that you have an excellent understanding of electronics, and physics, and have built, or are about to build an x-ray machine.
NEW! An inexpensive MINI FOCUS x-ray machine using an old radio tube.
Unlike the often used 2X2, PD500, 6EN4 etc, this unique tube produces x-rays from a SUBMILLIMETRE focal spot!
Using commercial X-ray diffraction tubes, for radiography.
The small focal spot, and low kVp, make these tubes ideal for radiographing delicate subjects, like plants and insects!
Flash X-rays from valves.
Using common valves (vacuum tubes), including some light bulbs,driven in flash x-ray mode, to generate x-rays, without the heat problems associated with driving radio tubes off of continuous DC.
Using commercial Flash X-ray tubes.
Using commercial Flash X-ray tubes, considerations, driving, shielding etc.
Modifying the Teltron Tel-x-ometer, to produce decent radiographs.
Whilst the Tel-X-ometer, is very safe, and works `out of the box`, it takes apalling radiographs. This guide describes the problems with the Tel-x-ometer, and steps for rectification. With care, exceptionally detailed radiographs can be produced of small objects.
Teachers, and Educators that have one of these in their lab, should definately consider this modification!
