Patent ID: 7424095

Claim:
An X-ray tube in which an anode and a cathode are disposed opposite each other in a vacuumized inner space, electrons being able to be produced at the cathode, being able to be accelerated to the anode by means of impressible high voltage, and X rays being able to be produced at the anode by means of the electrons, the X-ray tube comprising a multiplicity of mutually complementary acceleration modules, each acceleration module comprising at least one potential-carrying electrode, a first acceleration module comprising the cathode with electron extraction, and a second acceleration module comprising the anode with the X ray generation, wherein the X-ray tube comprises: at least one further acceleration module with a potential-carrying electrode, the acceleration module for acceleration of electrons being repeatedly connectible in series as often as desired, and the X-ray tube being of modular construction, said at least one acceleration module being interposed between the first and second acceleration module with the respective cathode and anode.
