Thermodynamics Coupling Analysis of Grid-Controlled Electron Gun

Abstract:

This paper carried out temperature analysis in the working state of the electron gun structure, the thermal deformation under high temperature and thermal stress analysis. Firstly, from the steady state temperature cloud chart of the electron gun we can see the cathode temperature is 985 °C, shadow grid temperature is same as cathode temperature, and the controlled-grid temperature is as high as 540 °C. Secondly, on the basis of thermal analysis, the coupled thermo-mechanical simulation technology is broken through; further thermal stress and thermal deformation at high temperature are analyzed. Thermal stress analysis results show that the maximum stress point is at contact area of cathode and its supporting tube. And the thermal deformation result shows that at high temperature under the action of thermal deformation, the axial distance of cathode-grid distance reduced 0.078 mm. Based on thermal deformation, the development personnel of microwave tube can use simulator to analysis the influence of thermal deformation to the electron gun design parameters, which can provide theoretical basis for tube design.
