| Abstract: | The electron gun and periodic permanent magnetic focusing system of grid-controlled traveling wave tubes(TWTs)were modeled and simulated with software packages MTSS and Opera for design optimization.The impact of the peak value of the magnetic field on the waist position of the electron beam was investigated.On this basis,the magnetic field in transition area was optimized and good matching between electron optical system and magneticsystem was obtained.The experiment shows that the statics circulationrate of the electron gun reaches 99.4%,which meets the design requirement. |
