Abstract: The newly practical field emission electron source has considerable radiographic significance in view of its very large current density, up to 108 amp/sq cm, or about a million times greater than that of the thermal emitter, heated wire, used in conventional x-ray tubes. As a result it is now possible to obtain high resolution radiographs, e.g. 2 mil, in very short exposure times of 30 nanosec. In one application, a sharp radiograph was obtained of 7-mil particles traveling at a velocity of 16,000 ft/sec. The present paper describes a new small portable x-ray system which was developed for very high radiographic information rates. It also reviews briefly the recent, but earlier, development of higher voltage equipments based on the T-F emission cathode which operates at intermediate current densities, e.g. 1000 amp/sq cm, and information rates.
