Vacuum electron device is meant in vacuum or gaseous medium, and owing to electronics or ion produce the amplification of signal and the active device of transition effects in interelectrode transmission, its important feature is exactly to reclaim the electron energy of finishing after the mutual effect by collector.Because the electronics after the mutual effect also has portion of energy not surrender, they will change into heat energy when electronics is got to collector, this has not only wasted energy, and for the heat radiation of collector has brought difficulty, and multi-level depressurization collector not only can energy savings but also can be reduced heat energy on the collector.Space travelling wave tube is because the restriction of the space energy and radiating condition, to high efficiency pursuit is an eternal problem, and multi-level depressurization collector is exactly an important channel of improving the space travelling wave tube gross efficiency, by improving the organic efficiency of multi-level depressurization collector, can effectively improve the gross efficiency of space travelling wave tube.The progression of multi-level depressurization collector is many more in theory, and the organic efficiency of collector is just high more, but in fact when progression surpasses level Four, the increase of its organic efficiency is very little, and the power supply way that progression increases requirement also increases, and has increased the complexity of power supply.So, generally adopt the level Four depressed collector.
Summary of the invention
The object of the present invention is to provide a kind of level Four depressed collector that is used for space travelling wave tube, to improve the organic efficiency and the heat-sinking capability of multi-level depressurization collector.
For achieving the above object, the level Four depressed collector that is used for space travelling wave tube provided by the invention, its primary structure is:
Same tubular type collector urceolus inside, the first collector electrode assemblie, the second collector electrode assemblie, the 3rd collector assembly and the 4th collector assembly distribute in the axially parallel order, leave certain clearance for insulation between each collector assembly, the contact conductor of each collector passes from the insulating ceramics hole;
