ABSTRACT:
A rotary piston tube for an x-ray radiator is provided in which the vacuum housing, accommodating an anode and a cathode and displaceable in rotation, comprises a 360° all-around ray exit window. For optimization of the ray exit window, this is produced according to one of the subsequently stated material specifications: a) a high-temperature steel or a high-temperature chromium and/or nickel alloy, listed in the standard EN 10273 and EN 10302, at a wall thickness between 0.1 to 0.4 mm; b) a titanium material at a wall thickness between 0.2 and 2 mm; and c) a ceramic material at a wall thickness between 1 mm and 5 mm.
