Numerical simulation of processes at the cavities of high-power 300 GHz gyrotrons

摘要

For some advanced fusion experiments and promising technological applications RF sources with CW power near 200–1000 kW and frequency 300 GHz and more are requested. In the framework of this project, investigation of processes of interaction of helical electron beam with RF field at the cavities of several design versions of a 300 GHz gyrotron with output power of 200–1000 kW for operation in the continuous regime was implemented at IAP RAS.
