摘要： An anode (A) closes one end of an evacuated envelope (C) and a cathode end plate (22) closes the other. A cathode assembly (B) is mounted on a bearing (40) in the evacuated envelope such that the envelope and cathode can undergo relative rotation. A motor (38) rotates the anode and envelope while a pair of magnets (44, 46) hold the cathode assembly stationary. Bearing (40) functions as a current path from a current source (72) to the primary windings of a transformer (58) . Another bearing (94) provides a return current path from the transformer to the current source. The secondary windings of the transformer are connected with a cathode filament (52) . The transformer enables a relatively low ampere current to pass through the bearings to limit cathodic damage to the bearings, yet provides sufficient amperage to the filament to cause thermionic emission. The bearings provide a direct transfer of current which does not degrade the vacuum in the envelope in such a manner that the current through the cathode filament can be measured directly from outside the envelope.

摘要： X-ray scanning system comprising a plurality of emitters and at least one receiver arranged opposite each other where only one emitter can be emitting at a certain time and so on until the exposure is performed, wherein each X-ray emitter comprises an anode (A) connected to a single power source (Aps) as well as a grid (G) and a cathode (K), where connected to each cathode there is at least one controller (CLR1) that controls the anode current (IA) and where each controller (CLR1) comprises a comparator (COMP) that has as reference the current demand of the anode (DIA), and the feedback of the comparator (COMP) is the actual anode current (IA). This allows avoiding the calibration of the cathode current demand value, maintaining the precision state in all X-ray emitters and shortening the activation and deactivation transition times.

摘要： Provided are a control device, a radiography system, a control method, and a control program that can shorten a calibration interval of a gate voltage supplied to a gate electrode of a radiation tube as compared to the related art.
Within one imaging period, a processor of a control device supplies a gate voltage, performs control to correct a voltage value of the gate voltage on the basis of a difference between a current value of an estimated anode current, which flows from a power supply voltage generator to an anode unit and is estimated on the basis of a detection value of a cathode current flowing from a cathode unit to a ground and a detection value of a gate current flowing from the power supply voltage generator to a gate electrode, and a target current value of an anode current set for an n-th imaging operation, and performs control to set the voltage value of the gate voltage corresponding to a corrected voltage value of the gate voltage corrected at the end of the n-th imaging operation and a target current value of the anode current set for an (n+1)-th imaging operation as a voltage value of the gate voltage which is supplied to the gate electrode first in the (n+1)-th imaging operation.
