Abstract. We present the results of theoretical analysis of depressed collector of the high power W-band extended interaction klystron. The computer code PARS was used for numerical simulation taking into account the secondary electron emission and backscattering from the collector walls surfaces. As a result of optimization, the design of double-stage depressed collector has been developed which provides spent beam energy recovery efficiency 72% in the static regime and 63% in the dynamic regime of klystron operation.
Key words: PARS computer code, electron beam, electron gun, depressed klystron, collector, focusing magnetic field, beam optics, secondary electron emission.
