【Abstract】 The model for thermal condition of an electron gun of TWT was established firstly. With ANSYS this thermal condition was simulated and analyzed. By changing some parameters of the electron gun’s structure and working condition, especially the size of the grid and the working power, different temperature distributions were obtained. These results supply efficient reference to the optimizing design and reasonable use of electron guns in TWT.更多还原
