Abstract. Possibility of increasing output power by BAC – method of electron grouping of S – band multiple-beam klystron at output power level of 10, 20 MW is discussed. Two samples of multiple-beam S – band klystrons «BT258» were fabricated and tested. Maximum efficiency of 64% at an output level of 6,4 MW was obtained.

Key words: vacuum electronics, multiple-beam klystron, BAC method.
