A power klystron amplifier and its driver system for a 6--Mev linear electron accelerator are described. The klystron is evacuated during its running by two specially designed oil diffusion pumps connected in series. Without using a liquid nitrogen trap the klystron works stable with the peak power output of 2 to 3 Mw. The average life of the oxide-coated cathode was more than 500 hours To keep a good frequency stability, a feed back oscillator with an invar cavity and a traveling wave tube is used as a masteroscillator. The output of this oscillator is l to 2 w at 2759 Mc, with the fluctuation being less than 20 kc. The output signal of the oscillator fs amplified by a pulsed traveling wave tube amplifier to drive the power klystron.
