The x-ray unit furthermore has a control circuit with which an operating property of the x-ray unit is adjusted and at least one measurement element for measurement of a measurement quantity is effectively correlated with the temperature of the cathode.

摘要： A charged particle beam including charged particles (e.g., electrons) is generated from a charged particle source (e.g., a cathode or scanning electron beam). As the beam is projected, it passes between plural alternating electric fields. The attraction of the charged particles to their oppositely charged fields accelerates the charged particles, thereby increasing their velocities in the corresponding (positive or negative) direction. The charged particles therefore follow an oscillating trajectory. When the electric fields are selected to produce oscillating trajectories having the same (or nearly the same) as a multiple of the frequency of the emitted x-rays, the resulting photons can be made to constructively interfere with each other to produce a coherent x-ray source.

摘要： An x-ray generating device includes a field emission cathode formed at least partially from a nanostructure-containing material having an emitted electron current density of at least 4 A/cm2. High energy conversion efficiency and compact design are achieved due to easy focusing of cold cathode emitted electrons and dramatic reduction of heating at the anode. In addition, by pulsing the field between the cathode and the gate or anode and focusing the electron beams at different anode materials, pulsed x-ray radiation with varying energy can be generated from a single device. Methods and apparatus for independent control of electron emission current and x-ray energy in x-ray tubes are also provided. The independent control can be accomplished by adjusting the distance between the cathode and anode. The independent control can also be accomplished by adjusting the temperature of the cathode. The independent control can also be accomplished by optical excitation of the cathode. The cathode can include field emissive materials such as carbon nanotubes.
