Abstract

PURPOSE:To suppress the counter-flow of the electron, by projecting a portion of a collector into the drift tube at the collector side of an output cavity while setting the length and the inner diameter of the linear section of said projection into specific relation. CONSTITUTION:A portion of a collector is projected into a drift tube 7 at the collector side of an output cavity 6. The inner wall of said projection 9 is linear and parallel with the tube axis, and assuming the length at the linear section is L while the inner diameter is (d) the following relation L>=2d is satisfied. With such structure the dell of the potential formed by the space charge of the electron beam can be made sufficiently shallow and the inversion of the low speed electron produced in the proximity of the collector can be suppressed.
