    摘要： An emitter for a closed x-ray tube includes an emitter body 152 formed of a low work function emitter material, the emitter body having a major surface 158 and a secondary surface 159B. The major surface is adapted for emission of electrons from the low work function material. The emitter assembly is adapted to reduce an emission current density emitted from the secondary surface of the emitter body, as compared to the major surface.

    摘要： In some embodiments, a cathode assembly may include a cathode head 802 that has a first electron emitter 803 and a second electron emitter 812. The first electron emitter may have a first connection location 808 and a second connection location 810. The second electron emitter may have a third connection location 814 and a fourth connection location 816. The third connection location may be electrically coupled with the second connection location of the first electron emitter. The cathode assembly may include a receptacle having a first connector 818 and a second connector 820. The first connector may be electrically coupled with the first connection location of the first electron emitter. The second connector may be electrically coupled with the second connection location of the first electron emitter and the third connection location of the second electron emitter. A third connector 822 may be electrically coupled with the fourth connection location of the second electron emitter.

    摘要： A RF generator includes a structure having an input section, an output section, and an opening extending between the input section and the output section, wherein the output section has a first cavity and a second cavity, and wherein the first and second cavities are spaced apart from each other so that they are electromagnetically uncoupled from each other. A method of providing RF energy, includes receiving an electron beam, providing a first RF energy through a first cavity, wherein the first RF energy is generated using the electron beam, and providing a second RF energy through a second cavity, wherein the second RF energy is generated using the electron beam, wherein the first cavity and the second cavity are spaced apart from each other so that they are electromagnetically uncoupled from each other.
