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.
