Quasi optical gyrotron : Present status and future prospect
The quasi-optical (Q.O.) gyrotron is an attractive alternative to the cylindrical cavity gyrotron at high frequency and high power. With an annular electron beam, theoretical efficiency as high as 30% could be achieved. A review of the main experiments on the Q.O. gyrotron is presented. The experiments described were performed with a large resonator. Methods to improve efficiency involved the use of an electron gun delivering pencil beams or the implementation of a depressed collector. The design of a depressed collector compatible with the use of a pencil beam still requires development.
