ABSTRACT:
An x-ray generator wherein the tube current is kept constant independently of the drop in the cathode temperature after the radiation is switched on has a control circuit for the tube filament current in which a correction value that corresponds to the drop in the tube current given constant filament current during the radiation phase due to the drop in temperature of the cathode is superimposed on the rated value of the filament current at the beginning of radiation.
