Super high power pulsed klystrons and multifrequency microwave electrovacuum devices. Obtained performances, prospects of development

The state of development of super high power klystrons is considered. It is shown that high power levels are achieved at the account of high anode voltages (200-500 kV). Proposed is the principle of obtaining super high pulsed powers with significantly reduced anode voltages thanks to placing single or multibeam klystrons with the magnetron gun in a common focusing solenoide with a uniform magnetic field as well as combining their output powers.
