摘要:
A cable for connecting to a connector of a high-voltage device includes an integral yield sensor. The yield sensor may be a pressure or force sensor, or a displacement sensor, including a stator part and a mobile part, and a spring for maintaining a compression force on the end portion of the cable towards the connector of the high-voltage device. The displacement sensor can include a Hall effect sensor and a linear array of magnetic elements arranged such that the Hall effect sensor moves relative to the linear array if there is any movement between the stator and mobile parts of the sensor, The magnetic field readings are interpreted in order to determine the amount of movement. A system for controlling a high voltage device in response to pressure and other information received from sensors in the cable is also provided.

摘要:
A device for generating X-rays or electron beams is described. The cathode of the device is mounted on a ceramic insulator which becomes hot during operation, and the ceramic insulator is cooled by means of a fluid coolant flowing around the outside of the insulator at the remote end of the insulator, away from the cathode. The coolant conduit can be formed by flange rings, soldered directly on to the surface of the insulator, and the conduit may be shaped such that the coolant is in direct contact with the insulator. A method for manufacturing the device is also described.

The present invention relates to a high-voltage x-ray tube (R) with an inner vacuum chamber (11) in which lie, oriented opposite one another, a cathode (8) held at a negative high voltage during operating conditions and an anode (2) held at a positive high voltage during operating conditions, wherein the anode (2) is affixed to an anode isolation element (3a) such that the anode isolation element (3a) has a cylindrical form or a form tapering toward the anode (2) and comprises an opening (5a) to receive a high-voltage plug (12) and has a conductor structure (6/7) via which a coolant can be supplied to the anode (2). This coolant can be, in particular, an insulating oil or another electrically nonconductive liquid. The conductor structure (6/7) can, for example, be integrated completely into the interior of the anode isolation element (3a) but can also be integrated into the surface of the high-voltage plug (12). In another possible solution, the conductor structure (6/7) is integrated into an intermediate element (13) which lies between the anode isolation element (3a) and the high-voltage plug (12).
