Abstract. We present the description of the PARS computer code algorithms, developed for the numerical analysis of physical processes in the high power vacuum electronic devices of klystron type, such as klystron, twystron, extended interaction klystron etc. The computer code is high-performance 2D analysis software package for researching and designing of devices from the cathode to the collector. It includes frequency-domain solver, electron optics module and beam-wave interaction time-domain solver. The algorithms use a self-consistent methods of numerical analysis of the charged particles dynamics in electromagnetic fields. Results of numerical simulation by computer code PARS of the high power klystron DESY 150 MW are presented. PARS simulation, experimental and other well-known computer codes results are in a good agreement.

Key words: computer code, electron beam, klystron, electron gun, cavity, collector, Poisson equation, Maxwell equations, particle in cell model, focusing magnetic field.
