摘要： An anode ( 16, 16' ) and a cathode ( 14, 14' ) are mounted in an evacuated envelope ( 12, 12' ) of an x-ray tube ( 10 ). One of the anode and cathode is rotatably mounted on bearings ( 20, 20' ) relative to the evacuated envelope. In the embodiment in which the anode is rotatably mounted relative to the evacuated housing, a rolling ring assembly ( 40 ) provides a current path from the anode through the evacuated housing to ground without the current path passing through the bearing ( 20 ). In this manner, pitting and other damage to the bearing due to arcing is eliminated. In the embodiment in which the cathode is rotatably mounted relative to the evacuated envelope, the anode and envelope rotate as the cathode is held stationary ( 58, 60 ). A plurality of rolling ring assemblies ( 40' 1 , 40' 2 , ...) provide electrical communication between electrical control circuitry disposed outside the rotating housing and the cathode assembly ( 14' ). The electrical communication includes providing current to filaments of cathodes ( 30' 1 , 30' 2 ) of the cathode assembly.

摘要： A ferrofluidic seal arrangement for sealing a high-speed rotary shaft (15) which passes between an environment at atmospheric or high pressure and an environment (14) at high-vacuum is provided, which is especially useful in a high-speed rotating anode apparatus for generating x-rays in a CAT Scan apparatus or the like. A differentially-pumped region (50) between a multi-stage ferrofluidic seal (19,22,48,49) and a single-stage seal (43 to 47) insures that no seal bursting into the-high-vacuum region occurs. Bearings (17, 18) supporting the shaft are arranged in a mechanically-stable arrangement but are isolated from the high-vacuum environment. Thus, neither the high-vacuum environment (14) nor the differentially-pumped region need be continually mechanically pumped, and a relatively light-weight apparatus results. The apparatus is electrically grounded by transferring the charge on the anode (58) through the high-speed shaft out of the vacuum environment and to a slower-rotating shaft (40) via an electrically conductive, flexible drive belt (37), the slower shaft rotating at a speed at which grounding by conventional means (41) is feasible.

摘要： A compact x-ray source can include a circuit (10) providing reliable voltage isolation between low and high voltage sides (21, 23) of the circuit while allowing AC power transfer between the low and high voltage sides of the circuit to an x-ray tube electron emitter (43). Capacitors (11, 12) can provide the isolation between the low and high voltage sides of the circuit. The x-ray source (110) can utilize capacitors of a high voltage generator (67) to provide the voltage isolation. A compact x-ray source (110) can comprise a single transformer core (101) to transfer alternating current from two alternating current sources (104a, 104b) to an electron emitter (43) and a high voltage generator (107). A compact x-ray source (120) can comprise a high voltage sensing resistor (R1) disposed on a cylinder (41) of an x-ray tube (40).
