Relativistic cyclotron accelerator exploiting the anomalous Doppler effect
Abstract
The characteristics of an experimental prototype cyclotron resonator using the anomalous Doppler effect are evaluated. A narrow axisymmetric electron beam passes through the ring gap of the retarding structure and the beam of synchrotron oscillators interacts with the transverse gap fields between the fins and the waveguide. The theoretical analysis utilized smallsignal theory with allowance for discrete interactions. The calculations were performed for a retarding system which was designed to use the electron beam produced by the highcurrent Tandem1 accelerator with pulse currents greater than 8 kA and voltages of about 500 kV. The frequency dependence of the signal power was determined to be in agreement with that given for the theoretical curve when the electron interaction coefficient equals zero, while if the electron interaction coefficient is not equal to zero then the cyclotron waves begin to interact with the spatial harmonics of the cellular structure in a way that depends on the size of the coupling and the field strength. The solution of the dispersion equation is presented.
