An x-ray tube is a simple device; a cathode emits electrons that strike a tungsten anode that emits x-rays. Most x-ray tubes, though, are relatively large with low-power mammography tubes being a ...

“The APS is a powerful and large (1.1 km circumference) outside of Chicago and provides very intense X-ray beams,” Toney ... the electrolyte and the cathode after the battery is fully charged.

It pays homage to the first X-ray ever taken, which was captured about 130 years ago. In 1895, when German physics professor Wihelm Röntgen was experimenting with cathode rays, he accidentally ...

DURING the course of work on behalf of the Radio Research Board of the Department of Scientific and Industrial Research, certain phenomena have been observed in high vacuum cathode ray tubes of a ...

In the early part of the 20th century, it was the first name given to electron beams emitted from a negatively charged cathode in a vacuum tube. The term has been used ever since. See CRT.
