Abstract

PURPOSE: To obtain a fixed amount of X-ray for its radiation by detecting the magnet flux generated in the iron core of a high voltage generating device during the radiation of X-ray for determining thereby the phase of the voltage to be added to the primary side of the high voltage generating device at the time of throw-in.
CONSTITUTION: The extent and direction of the magnetic flux generated in an iron core 3 are detected from tertiary windings 5-1∼5-3 wound around the iron core 3 of a high voltage generating device 2. This output is input into a discrimination circuit 8, after it is integrated by integrators 7-1∼7-3 composed of a resistance, condenser, and operational amplifier. The discrimination circuit 8 controls a gate circuit 10 for thyristors 1-1∼1-6 through a signal control circuit 9 for controlling the succeeding radiation of X-ray to obtain a fixed level.
