Abstract
An x-ray tube has a cathode and an anode produced from a first material, the anode having a heat conductor element on the first side thereof facing away from the cathode. To improve the performance of the x-ray tube, the heat conductor element is composed of graphite doped with titanium having a heat conductivity of at least 500 W/mK.
Claims10
An x-ray tube comprising:
- a cathode;
- an anode comprising a first material, said anode having a side facing away from the cathode;
- and
- a heat conductor element disposed at least in a section of said side of said anode facing away from the cathode, said heat conductor element comprising a second material exhibiting a higher heat conductivity than said first material, for dissipating heat from said anode, said second material comprising graphite doped with titanium exhibiting anisotropic heat conductivity of at least 650 W/mK with a direction of a maximum of said heat conductivity oriented substantially perpendicular to said side of the anode facing away from the cathode.
