摘要： An evacuated envelope is formed with a portion of larger diameter and tubular portions extending along the axis on both sides of the portion of larger diameter in opposite directions. A target with a rotatable anode is arranged in the portion of larger diameter. A pair of shafts arranged on the tube axis and fixed on both sides of this target are arranged in the tubular portions. Each shaft has at least one flange of insulating material on the side facing the target and on its periphery is provided with a metal tube constituting a rotor of a magnetic bearing. On the outermost side of the tubular portion there are arranged a magnetic field generating device and a magnetic drive device that rotates the rotatable anode target.
