Coolidge’s X-Ray Tube

The Coolidge tube is one of the most widely used X-Ray tubes in the past. Early cold cathode tubes were unreliable and was very hard to control the intensity of the X-rays. However, William D. Coolidge improved it to be the hot cathode tube. In addition, the tube will function as long as it is not badly abused. Despite its advantages and superiority over the early cold cathode tubes, it did not have widespread use immediately.
