- 8 - CATHODE/HEATER ASSEMBLY FOR ELECTRON-BEAM DEVICES ABSTRACT A cathode/heater assembly comprises an emitter mounted on at least one heater element fitted to current-conducting leads rigidly fixed to a base of electrically insulating material, mounting a repeller with a concave surface fac- ing the emitter's nonoperating surface and having a focal length of at least one and a half times greater than the emitter's transverse dimension. The spacing L from the re- peller to the emitter is within the limits from 0.15R to 0.75R, where R is the radius of curvature of the repel- ler's concave surface in the axial direction.
