Abstract
A cooled radiation emission device has an enclosure in which X-rays are produced. In the enclosure, there is a cathode, an anode situated facing the cathode and rotating on a shaft, and a fixed anode shaft support. The support includes a holding chamber, the shaft of the anode being held in the chamber. The cooling of the tube uses a gallium-indium-tin liquid alloy flow through the anode shaft. This alloy is a conductor of heat and electricity. At the same time as the lubrication of the bearings and the electrical powering of the anode, it provides for cooling of the anode.
Claims58
A radiation emission device comprising:
- an enclosure in which radiation is produced;
- in the enclosure, a cathode, an anode situated facing the cathode and rotating on a shaft, and a fixed anode shaft support;
- the support comprising a holding chamber and, in this chamber, a ball bearing;
- the shaft of the anode being held in the chamber by the bearing;
- the chamber of the support is filled with a liquid alloy in which the bearing is immersed;
- and
- means for cooling to cause the liquid alloy to penetrate the chamber and cause it come out during a use of the device.
