The absence of the «defect» efficiency in the clinotrons
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The paper exposes the fact that the effect of limiting efficiency (efficiency "deficiency") arising in O-type devices with a collector outside the region of electron-wave interaction because of energy accumulation in the potential field of the phase ...
