Abstract

The invention belongs to the high-efficiency technical field of traveling wave tubes, and in particular relates to a method for measuring electron energy distribution curves at the inlet of a traveling wave tube collector. The present invention starts to test the traveling wave tube by using low working ratio electron injection and emission, and gradually increases the working ratio of the traveling wave tube under the premise of ensuring safety, until the working ratio of the traveling wave tube can no longer be increased. At this time, the measured data is final measurement data. The final measurement data is used to guide the iterative optimization design of high-efficiency collectors and the debugging of high-efficiency collectors, which reduces the iterative development times and design cycle of high-efficiency traveling wave tubes, and helps reduce the cost of high-efficiency traveling wave tubes. Development costs. And the present invention is convenient and simple to operate, does not need to manufacture complicated test system, greatly saves time and experiment cost.

Description

technical field

[0001] The invention belongs to the high-efficiency technical field of traveling wave tubes, and in particular relates to a method for measuring electron energy distribution curves at the inlet of a traveling wave tube collector. Background technique

[0002] Traveling wave tubes are broadband and high-power vacuum electronic devices with high efficiency, large bandwidth, high reliability, long life and radiation resistance, and are widely used in radar, satellite communication, navigation and other fields. High efficiency is one of the development goals of traveling wave tubes. High efficiency means that the energy conversion efficiency of traveling wave tubes is high. Under the limited energy supply of traveling wave tubes, it helps to save system energy; it also means that in the same With a high energy supply, the satellite payload can be increased; high efficiency also means low energy loss, and the heat energy converted from the electrical energy lost b...
