摘要：

The multistage depressed collector (MDC) is essential to significantly increase the overall efficiency of the gyrotron. To date, a short pulse (SP) MDC prototype system has been manufactured and is currently under test. The long-term goal that makes the most sense is to use MDCs on 2-MW fusion gyrotrons in continuous wave (CW) operation. To achieve this, a CW MDC system based on the same physical principle as the SP system is designed and analyzed for the first time. The highlights of this design are the sweeping systems to keep the thermal loading within an acceptable limit when the MDC is operated in CW. In the present analysis, the expected performance and size of the new CW MDC design are compared with that of the SP MDC prototype and with the corresponding single-stage depressed collectors (SDCs) as a reference. In addition, the effects of thermal expansion in CW operation are analyzed and discussed.
