ABSTRACT:
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.
