Abstract

The invention discloses a method used for slow wave welding test of a travelling wave tube. A clamp comprises a clamp base, wherein a through slot is formed in the axial direction of the clamp base; a false window is arranged on the end surface of the clamp base; fastening threaded holes are formed in the side surface of the clamp base; a group of slow wave structural parts used for welding is arranged in the through slot; an input hole and an output hole are formed in each slow wave structural part; each output hole or input hole corresponds to the false window in position; and a baffle block used for blocking each output hole or each input hole is arranged in the false window. The integrated clamp used for slow wave welding test of the travelling wave tube integrates a welding function and a test function, realizes coaxiality requirements of slow wave structural parts during welding, further can complete test on voltage-standing-wave ratio characteristics in case of not dismounting the welding clamp, saves assembly time, improves test precision, reduces risk on welding of slow wave structural parts, and increases the yield of slow wave structures.

Description

technical field [0001] The invention relates to the technical field of microwave electric vacuum devices, in particular to a method for slow-wave welding testing of traveling wave tubes. Background technique [0002] The traveling wave tube is an electric vacuum device that amplifies the input microwave signal. It has the characteristics of high power, wide bandwidth and high gain. It has been widely used in the fields of electronic countermeasures, radar systems and high-speed wireless communications. Folded waveguide traveling wave tube has become one of the micro-electrical vacuum devices with application prospects in the frequency band above 100 GHz due to its high-frequency structure with all-metal structure, fewer competing modes, and large power capacity. Therefore, the terahertz folded waveguide traveling wave tube It has received extensive attention and research, and has shown great application potential in the fields of high-resolution terahertz radar, long-distanc...
