  1. Design considerations of the high power s - band rka are described, by using electron beams of voltage - 600kv, current - 5000a, and the numerical simulations for three kinds of the rka output structures are given. the three kinds of the output strctures are single - gap standing - wave ( sw ) cavity, traveling - wave ( tw ) output structure, and two output structures ( single - gap + traveling - wave structure ). under conditions of using two output structures, the results show that the instantaneous peak power obtained from sw output cavity and tw output structure is respectively 2. 4gw and 2. 1gw, the both power average of 0. 96gw and 0. 93gw, i. e. the s - band rka of two output structures generates peak output power of 1. 89gw at a frequency of 2. 85ghz

    從數值模擬中得到雙輸出結構的微波功率輸出結果為:駐波輸出的瞬時功率為2 . 4gw (周期平均為0 . 96gw ) ;行波輸出結構輸出瞬時功率為2 . 1gw (周期平均0 . 93gw ) ,就獲得了頻率為2 . 85ghz的微波輸出。本文簡要的描述了電磁軟體( magic )對速調管輸出腔體進行了模擬,並對相應的模擬方法進行了評述。
  2. Band spread system enables you to easily tune in sw stations
