ABSTRACT:
An X-ray radiation control apparatus comprises an X-ray tube, tetrodes each connected between the anode and the cathode of the X-ray tube, and tetrode controlling circuits connected thereto. Each of the tetrode controlling circuits controls the anode voltage drop of the respective tetrode for stabilizing a high-tension DC voltage to be applied to the X-ray tube as well as removing ripple components therefrom. Each tetrode controlling circuit is constituted by a first high-voltage transistor for producing a first grid bias controlling voltage for stabilizing the high-tension DC voltage and a second high frequency transistor for producing a second grid bias controlling voltage for absorbing the ripple components contained in the high-tension DC voltage.
