Description
technical field [0001] The invention relates to a collector lead wire of a space traveling wave tube, in particular to a highly reliable welding structure and a welding method for the collector lead wire of a radiation-cooled space traveling wave tube. Background technique [0002] The high-voltage lead wire connected to the collector of the space traveling wave tube is the only interface for the DC power supply of the collector of the traveling wave tube. The failure of the collector lead wire connection directly leads to the disconnection of the power supply of the collector electrode of the traveling wave tube, the loss of the ability of the collector electrode of the traveling wave tube to receive electrons, and immediately forms a large backflow (spiral flow), which makes the spiral flow of the traveling wave tube overcurrent and cannot be powered on. [0003] The lead wire welding part of the radiation-cooled space traveling wave tube collector is located inside the he...
