How to improve the efficiency of the gyrotron is always the focus of attention in studying gyrotron. There are many way to enhance the efficiency of the gyrotron, which are mainly concentrated in two aspects, one is designing the gyrotron with a depressed collector, the another is by changing the cavity structure to improve efficiency. In the paper, we adopt a new cavity structure which can better...
A complex cavity with gradual transition is employed in the 94 GHz gyrotron. A self-consistent field nonlinear theory has been used and numerical simulations for electron beam interaction with RF modes are given. A pulse output power of 235.2 kW is obtained by simulation at a beam voltage of 60 kV with beam current of 10 A, a velocity ratio of 1.45, and magnetic field 17kG, corresponding to an efficiency...
A complex cavity with gradual transition is employed in the W-band gyrotron. A self-consistent field nonlinear theory has been used and numerical simulations for electron beam interaction with RF modes are given. A pulse output power of 212 kW is obtained by simulation at a beam voltage of 60 kV with beam current of 10 A, a velocity ratio of 1.5, and magnetic field 17kG, corresponding to an efficiency...
Cyclotron electron beam provided by magnetron injection gun has a direct impact on the performance of the whole gyro-devices. Based on the initial study and computer simulations, A 10 A single-anode electron gun has been studied and designed according to the requirements of the gyrotron. Calculations have been performed to optimize the electrode shape and the beam parameters. The electron beam with...
Open cavity with abrupt changes is generally used in the gyro-oscillators and amplifiers. On the basis of mode-matching technique we present the high frequencies structure analyses code for gyrotron. The code provides a method for computing the resonant frequency and Q value in an open cavity. We present the theory and an example which demonstrates the operation and the possible usage of the code.
