X-ray apparatus

摘要

The present invention is characterized by supporting a stator to generate a magnetic field and an anode target by a dynamic pressure plain bearing using a liquid metal, and cooling at least the inside of the dynamic pressure plain bearing and an enclosure containing an anode target by circulating one kind of cooling medium, in a rotary X-ray tube apparatus which obtains X-rays by impinging an electron on an anode by rotating an anode target.
