Generation of X-Rays

Abstract

In Röntgen’s investigations of the properties of X-rays he found that X-rays are generated whenever cathode rays strike a solid body and are stopped by it. Thus, in order to generate X-rays, three main components are required, namely, a source of cathode rays or electrons, a means of accelerating them and a solid target to stop them. In most modern X-ray tubes the source of electrons is a heated filament and the necessary acceleration is produced by a large potential difference applied between the target and the electron gun. Thus an X-ray generator consists of an X-ray tube together with equipment to provide the necessary electrical supplies.
