Abstract
1. Плазменный катод, содержащий полый держатель с торцевыми стенками и проходными отверстиями рабочего тела, внутри которого размещен эмиттер, между которыми расположен барьерный слой химически пассивного материала, отличающийся тем, что между внутренними поверхностями полого держателя и наружными поверхностями эмиттера образованы зазоры, между которыми размещен экран, поверхности которого покрыты барьерными слоями.2. Плазменный катод по п.1, отличающийся тем, что зазор между внутренней поверхностью полого держателя и наружной поверхностью эмиттера выполнен со стороны выхода протяженностью по меньшей мере половины высоты эмиттера.3. Плазменный катод по п.1, отличающийся тем, что края экрана заведены между торцевыми стенками полого держателя и эмиттера.4. Плазменный катод по п.1, отличающийся тем, что экран выполнен из химически пассивного материала относительно эмиттера.5. Плазменный катод по п.1, отличающийся тем, что между торцевыми стенками полого держателя и эмиттера со стороны входа рабочего тела установлен упругий элемент.6. Плазменный катод по п.5, отличающийся тем, что дополнительно поверхности упругого элемента покрыты барьерным слоем.1. Plasma cathode containing a hollow holder with end walls and through holes of the working fluid, inside which an emitter is placed, between which a barrier layer of a chemically passive material is located, characterized in that gaps are formed between the inner surfaces of the hollow holder and the outer surfaces of the emitter, between which a screen whose surfaces are covered with barrier layers. 2. The plasma cathode according to claim 1, characterized in that the gap between the inner surface of the hollow holder and the outer surface of the emitter is made on the output side with a length of at least half the height of the emitter. The plasma cathode according to claim 1, characterized in that the edges of the screen are wound between the end walls of the hollow holder and emitter. The plasma cathode according to claim 1, characterized in that the screen is made of chemically passive material relative to the emitter. The plasma cathode according to claim 1, characterized in that an elastic element is installed between the end walls of the hollow holder and the emitter from the input side of the working fluid. The plasma cathode according to claim 5, characterized in that the surfaces of the elastic element are additionally covered with a barrier layer.
