A new x-ray device possesses an x-ray tube with a beryllium aperture, the voltage is regulated from 10 to 80 kV and currents from 2 to 10 mA. Feeding frequency of the main part of the unit is 20 kHz. A closed single-contour cooling water circuit is used. Pulsation of the voltage in the x-ray tube is no higher than 0.1% for the whole range of anode voltage of the tube. Typical values of the radiation output in P/min mA for different values of the extra aluminium filters are presented. The metrological characteristics of the device meet the MEK 601-2-8-87 requirements for x-ray equipment.
