三阴极强流加速器研制
High power accelerator with three cathodes
-
摘要: 研制了一台能同时产生3电子束的高功率强流加速器，该加速器主要由初级储能部分、线绕式脉冲变压器、水介质形成线和三阴极二极管组成，3根阴极分别伸入3个独立的漂移管，对3个电子束之间相互作用的电磁力起屏蔽作用。当该加速器二极管接单个阴极时，产生的电功率超过50 GW；当该加速器二极管同时接3个阴极时，产生3个电子束的电功率分别超过10 GW;当该加速器被用于驱动3个高功率微波管时，能产生L波段1.0 GW,S波段1.0 GW和C波段300 MW的微波输出。Abstract: A high power accelerator which can simultaneously produce three electron beams was developed. It is made up of primary energy storage system, spiral-strip transformer, pulse forming line using deionized water as insulation and diode with three cathodes. The three cathodes are stretched into three separate drift tubes, which can isolate the electromagnetic force between the produced electron beams. When a single cathode is connected to the diode, the accelerator can produce over 50 GW electric power; when three cathodes are connected to the diode, three electron beams each with over 10 GW electric power are produced. When the accelerator is used to drive three microwave tubes, three microwaves of 1.0 GW (L-band MILO), 1.0 GW(S-band MILO) and 300 MW(C-band VCO) can be obtained.
