Abstract:
In this paper a model for calculation of heat transfer of the cathode assembly in vidicon has been given. Five cathode assemblies with different constructions have been calculated by computer. The calculated results prove the model is reasonable. In ...

Abstract:
Starting from the view point of the coherent cyclotron radiation, we work out the phase condition of the Weibel instability gain mechanism and make a comparison with the phase condition of the cyclotron maser gain mechanism. Moreover, we propose a co...
