In this paper, the simulation and design of a diode type magnetron injection gun (MIG) for a W-band CW gyrotron oscillator is presented. The simulation of the MIG, operating at the voltage of 55kV and the current of 4A, is finished with the help of a trajectory program EGUN. The simulation results indicate that the velocity ratio with velocity spread of less than 2.5% is 1.43.
In this paper, the design of a magnetron injection gun (MIG) with a single-anode built for W-band gyrotron oscillator is presented. The simulation of the MIG is finished with the help of a trajectory program EGUN. The simulation results indicate that the velocity ratio with velocity spread of less than 4% is 1.41.
The problem of sliding mode control for uncertain time-delay systems with input saturation and known external disturbance is considered. Combining T-S fuzzy model and sliding mode control method, we first establish the T-S model for the system, then an integral switching function is chosen, and a special sliding mode controller is designed such that the state trajectories can be driven onto the specified...
In this paper, the prototype and design of the double-beam magnetron injection gun (MIG) of the gyrotron is presented. The double-beam MIG is simulated and designed by the particle-in-cell (PIC) software CHIPIC and the steady-state beam trajectory software EGUN respectively. The simulation results of the double-beam MIG by the two type of the software are compared.
A high power gyrotron traveling-wave amplifier operating in the low-loss TE01 mode has been designed. The amplifier will be driven by a 70-kV, 10-A electron beam with a pitch angle (vperp/v//)of unity and velocity spread of 3~5% generated by a double-anode magnetron injection gun (MIG).The amplifier is predicted by nonlinear theory simulation code to generated 180 kW at 35 GHz with 25 efficiency,...
