    Abstract: A metal frame x-ray tube (1), includes a gettering system (90) which, when activated, provides a layer (147) of gettering material (98) on a grounded conductive portion (72, 74) of a metal frame or envelope (14). The envelope defines an evacuated chamber (12), which houses an anode (10) and a cathode (18). Moving the gettering material to larger diameter portions of the frame enables substantially larger amounts of gettering material to be provided than in a conventional gettering system, which is typically housed in the cathode assembly (26). Moreover, multiple independently controllable gettering wires (92, 94) facilitate reactivating the gettering material plural times both during the manufacturing process and in the field. This ability to rejuvenate vacuum pumping capability in an x-ray tube that is starting to arc in the field allows for extended x-ray tube life.

    Abstract: An X-ray tube includes an evacuated envelope; a cold cathode mounted at one end of the envelope and capable of field emission of electrons when subjected to a high electrostatic field; and an anode mounted at the opposite end of the envelope coaxial with and axially spaced from the cathode, and capable of emitting X-rays when struck by electrons emitted by the cathode. The envelope includes an end wall made of thermally-conductive and electrically-insulating material in contact with the anode and formed with a fluid cooling channel to remove the heat generated at the anode. In one described embodiment, the cathode includes a body of a getter material which is both electron emissive and gas absorptive. In other described embodiments, the cathode includes a carbon nanotube field-emission electron source.
