X-Ray Tube for High Dose Rates, Method of Generating High Dose Rates wit X-Ray Tubes and a Method of Producing Corresponding X-Ray Devices

摘要

The invention relates to an X-ray tube ( 11/12 ) for high dosing performances, a corresponding method for the production of high dosing performances with X-ray tubes ( 11/12 ) and method for the production of corresponding X-ray devices ( 11/12 ), wherein an anode ( 31/32 ) and a cathode ( 21/22 ) are arranged opposite each other in a vacuumed internal chamber ( 41/42 ). Electrons (e^-) are accelerated by means of high voltage which can be applied to the anode ( 31/32 ). The anode ( 31/32 ) is made of a metal layer having a high ordinal number which is used to convert the electrons (e^-) into X-ray radiation (Y) with the aid of a coolant. The cathode ( 21/22 ) comprises an essentially transparent carrier material for X-ray radiation (Y) and an essentially transparent electron emitter layer for X-ray radiation (Y). According to the invention, the cathode ( 31/32 ) can, in particular, close the vacuumed internal chamber ( 41/42 ) from the outside.
