Gyrotron electron gun structure and assembling method thereof

The invention discloses a gyrotron electron gun structure which comprises a lead assembly structure (1), a gun shell assembly structure (2), a cathode hot filament assembly structure (3) and an anode(4). The anode (4) is arranged in the gun shell assembly structure (2), one end of the cathode hot filament assembly structure (3) extends into the gun shell assembly structure (2) to be assembled with the anode (4), and the other end of the cathode hot filament assembly structure (3) is connected with the gun shell assembly structure (2) through the lead assembly structure (1). The invention further provides an assembly method of the gyrotron electron gun, the method has the characteristics of good process repeatability and consistency, the assembled electron gun is high in structural size precision and concentricity, the reliability of an electron gun cathode assembly filament is high, and the air leakage rate of the electron gun structure is low. 本发明公开了一种回旋管电子枪结构，包括引线组件结构(1)、枪壳组件结构(2)、阴极热丝组件结构(3)和阳极(4)；其中，阳极(4)
