摘要： An x-ray tube is presented. One embodiment of the x-ray tube includes a cathode unit configured to emit electrons. The x-ray tube further includes an anode unit positioned to receive the emitted electrons, wherein the anode unit includes a base having a target surface configured to generate x-rays when the emitted electrons impinge on the target surface. Also, the anode unit includes a first shielding unit enclosing the base to attenuate at least a first portion of the generated x-rays within the anode unit.

摘要： A motion correction system and method for motion correction for an x-ray tube is presented. One embodiment of the motion correction system includes a sensing unit coupled to an x-ray tube to determine a distance with which an impingement location of an electron beam generated by the x-ray tube deviates from a determined location due to motion of the x-ray tube. The motion correction system further includes a control unit coupled to the sensing unit to generate a control signal corresponding to the distance with which the impingement location of the electron beam deviates. Also, the motion correction system includes a deflection unit coupled to the control unit to steer the electron beam to the determined location based on the generated control signal.

摘要： Systems, apparatus, and program product and methods for controlling boundary layer flow across an aerodynamic structure which can produce separate regions of flow structures at different strengths by means of dielectric-barrier-discharge (DBD) type plasmas, are provided. An example of such apparatus provides plasma regions that are capable of being individually controlled by voltage and/or frequency, and modulated for the purposes of flow control. The apparatus includes an electrode assembly fitted with electrodes on either side of a dielectric such that different electrode geometries and arrangements create isolated regions of plasmas which results in separate regions of flow structures. These regions may be further controlled and modulated by the use of electronic-switching to produce irregularly shaped flow structures and strengths including those having a primarily vertical component.

摘要： A high voltage, fast pulse rise/fall time, and high repetition rate pulse generator solves the high pulse repetition rate limitations associated with RF power amplifiers and gap switch type pulse generators. The pulse generator employs a transmission line architecture and structural techniques that allow for continued high voltage, fast rise/fall time, and high repetition pulse rate operation of the pulse generator without impairment of the pulse generator while exceeding performance characteristics achievable with conventional RF power amplifiers and gap switch type pulse generators.
