Electron-optical system for orotron with permanent magnets

The results of simulation of a new electron optics system, forming high-current sheet electron beam for power orotron, integrated with permanent magnets, are presented. Transversally magnetized rectangle magnets are installed in the plane, and resonant system might be mounted in a direction perpendicular to that of the plane. The electron gun and collector are positioned in inner cavities of pole pieces and are shielded of a magnetic field. The gun makes the sheet electron beam with a linear compression 5, transversal dimensions in a channel 0.1 times 14 mm², current - 2.8 A and current density 200 A/mm². In the collector the divergent beam is formed to decrease heating density on the surface. The anode voltage - 6 kV, focusing magnetic field -6 kGs in the pole gap 29 mm.
