摘要： An advanced center post (ACP) gun is provided which is capable of producing either a large orbit or small orbit electron beam. The gun comprises an annular shaped cathode, a control electrode adjacent the cathode, and an annular anode having an opening therethrough. A center post is disposed axially within the center region of the cathode and the control electrode along a center line of the electron gun and interaction region of a microwave device. The anode is shaped in conjunction with the center post to control position of equipotential lines of an electric field provided in an inter-electrode space between the cathode and the anode so that an electron beam emitted by the cathode converges at the anode opening. The control electrode provides electrostatic focusing of the beam to further control the beam convergence. Multiple polepieces provide accurate control of the magnetic field in the interaction region to shape the beam and control the orbit size and velocity spread.

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.

摘要： A depressed collector is provided which is capable of recovering energy from a large orbit gyrating electron beam received from a microwave device, such as a gyrotron. The depressed collector sorts and collects the electrons of the spent electron beam on the basis of their radial energy levels. The depressed collector comprises a plurality of stages of electrodes. Each of the electrode stages have a negative potential applied thereto, with the first of the electrode stages having the greatest negative potential with respect to the microwave device, and the subsequent stages having decreasing relative potential. The depressed collector will sort the electrons from the gyrating electron beam in accordance with their radial energy, with electrons having the highest radial energy being collected on the first electrode, and electrons having lesser amounts of radial energy being collected on the subsequent electrodes.
