ABSTRACT:
A linear source of x-rays is disclosed wherein an elongated filament, mounted within a cylindrically formed anode, provides electrons around the filament, and along the length of said filament. The anode that comprises a high Z material such as gold, receives the electrons and emits X-rays in a 360 degree arc and along a substantial length of the anode. In one embodiment the tube is used for irradiation purposes.
