Patent ID: 7515687

Claim:
A device for the emission of X-rays, comprising: a vacuum enclosure, delimited by a sealed wall, a vacuum pump, comprising: a sealed peripheral casing; a stator, a rotor; and a control means enabling stable rotation of the rotor at a very high speed, wherein the vacuum pump is connected to the vacuum enclosure to generate and maintain a vacuum therein, a cathode disposed within the vacuum enclosure which generates a flux of electrons, a rotary anode disposed within the vacuum enclosure, which is driven in rotation about a rotation axis and receives, at its periphery, the flux of electrons coming from the cathode to emit X-rays toward an exit, and at least two cooling elements, each disposed opposite respective main radial faces of the rotary anode to absorb radiated heat energy emitted by the rotary anode in operation, wherein one of the at least two cooling elements is fixed to the vacuum pump stator and another of the at least two cooling elements is fixed to the sealed peripheral casing; wherein: the rotary anode is attached to the rotor of the vacuum pump, and is disposed coaxially with the rotor, and the sealed peripheral casing of the vacuum pump itself constitutes at least a portion of the sealed wall of the vacuum enclosure.
