  An 1.5 GHz, 13.5 kW CW high-power mag­netron for a su­per­con­duct­ing RF ac­cel­er­a­tor has been de­vel­oped by An­desun Tech­nol­ogy Group Co., Ltd. with Nan­jing Sanle Elec­tronic In­for­ma­tion In­dus­try Group Co., Ltd., in order to re­place the kly­stron, that could re­duce the power source cost to about one-third. The cav­ity, out­put power an­tenna and cou­pling door-nob have been op­ti­mized by using CST Stu­dio. Test­ing re­sults have shown that the res­o­nance fre­quency and out­put power have met the re­quire­ments, and the ef­fi­ciency of the mag­netron is higher that 78.45%.

  A 150.4MHz to 155.4MHz, 300W con­tin­u­ous wave solid-state am­pli­fier as an ac­cel­er­a­tor power source has been de­vel­oped by us. In order to in­crease the life­time of MOS­FET and meet the re­quire­ments of every pa­ra­me­ters, Drain volt­age and qui­es­cent cur­rent is set at a bet­ter point with a well-de­signed heat dis­si­pa­tion struc­ture, we make the solid state am­pli­fier sta­ble in per­for­mance. Tak­ing the mi­crowave leak­age into ac­count, the chas­sis struc­ture is op­ti­mized and de­signed, and the mi­crowave ab­sorp­tion de­vice is adopted to make the struc­ture com­pact, pro­tect other parts not af­fected by the mi­crowave leak­age. After the as­sem­bly is com­pleted, the work­ing pa­ra­me­ters meet the de­sign re­quire­ments very well. The MOS­FET flange tem­per­a­ture and out­put pa­ra­me­ters meet the de­sign re­quire­ments.
