ABSTRACT:
Disclosed is a reusable microfocus X-ray tube adapted to generate a relatively large number of X-rays in a relatively short period of time using a narrowly focused electron beam. The X-ray tube comprises means for producing a dense, narrow electron beam, a target anode, and means for causing relative movement of the electron beam and the target anode such that the electron beam and the target anode are stationary relative to each other during production of the X-rays but a fresh portion of the surface of the target anode is presented to the electron beam each time the X-ray tube is used. The X-ray tube includes (a) means for collecting charged particles boiled off the target anode by the electron beam, (b) means for increasing the quantity of electricity delivered to the heater cathode, (c) means for counting the number of times the X-ray tube is used, and (d) means for generating a signal when the X-ray tube has been used a first predetermined number of times.
