Abstract
X-ray tube (11/12) for high dose rates, a corresponding method for generating high dose rates with X-ray tubes (11/12) as well as a method for producing corresponding X-ray devices (11/12), in which an anode (31/32) and a cathode (21/22) are disposed opposite each other in a vacuumized internal chamber (41/42), electrons e− being accelerated to the anode (31/32) by means of impressible high voltage. The anode (31/32) is made of a layer or coating of a metal having a high atomic number, for conversion of the electrons (e−) into X-ray radiation (γ) with cooling. The cathode (21/22) comprises a substrate substantially transparent for X-ray radiation (γ). In particular, the likewise substantially transparent for X-ray radiation (γ). In particular, the cathode (31/32) can close off the vacummized internal chamber (41/42) toward the outside.
