Embodiment 1

[0056] Baking and degassing in the vacuum furnace: Install the row pipe of the return wave tube and press it on the exhaust channel of the exhaust table through the screw, and lower the bell jar of the exhaust table. according to figure 1 The time-temperature curve is vacuum baked and the molecular pump and ion pump are turned on for degassing;

[0057] High-voltage wire welding: for the soldering wire of the output electrode of the return wave tube after baking and degassing, the color code of the wire of different colors is used to distinguish the soldering of the output electrode of the return wave tube and the color code of the wire, such as figure 2 ;

[0058] Insulation potting: evenly coat (0.5-1)mm 703 silicone rubber on the ceramic part of the return wave tube electron gun after soldering the high-voltage wires, let it stand for no less than 24 hours, and then carry out the potting through the potting tool (as shown in Figure 3). Potting of insulating silicone rubb...

Abstract

The invention discloses a method for simultaneously testing the frequency and power of a return-wave tube oscillating microwave signal, comprising: step 1, degassing the return-wave tube in a vacuum oven to obtain A; step 2, soldering wires to the output electrode of A, The different output electrodes of the return wave tube are distinguished by the color codes of the wires of different colors to obtain B; step 3, evenly coat the ceramic part of the electron gun of B with silicone rubber and let it stand for no less than 24 hours, and then pour the insulating silicone rubber Seal and let stand for no less than 12 hours to obtain C; step 4, install the magnetic system fixing bracket on C to obtain D1, then install D1 in the magnetic system to obtain D2, install D2 on the three-axis adjustment tooling and D is obtained by fastening the connection part. The invention can simultaneously measure the oscillation frequency and oscillation power of the return wave tube in operation.

Description

technical field [0001] The invention relates to the technical field of electric vacuum microwave devices, in particular to a method for simultaneously testing frequency and power of microwave signal oscillations in a return wave tube. Background technique [0002] In recent years, the development of terahertz technology has received special attention, and the return wave tube is the microwave oscillation source that oscillates to generate terahertz frequencies, because it has important application prospects in national defense, civil and scientific research. It is understood that terahertz Potential applications of the technology include high-data-rate communications, detection of concealed weapons, high-resolution imaging, deep space exploration, medical diagnostics, and materials research, among others. [0003] At present, the research of terahertz technology by relevant national scientific research institutes mainly focuses on the three major contents of terahertz source...
