摘　　要：　设计了一种可机械调谐的S波段相对论磁控管,该管采用由5个扇形腔和5个矩形腔组成的旭日型磁控管方案,通过小腔滑块移动实现调谐。利用等效电路法和高频场分析软件与粒子模拟软件分析了器件的性能。初步模拟结果表明:调谐相对带宽可达20%,当电压为650kV,磁场为0.6T时,全带宽内输出功率大于600MW,在大部分带宽内峰值功率大于900MW。A kind of S-band frequency agile relativistic magnetron is designed, which adopts the scheme of rising-sun magnetron with 5 fan-shaped cavities and 5 rectangular cavities. Through adjusting the site of metallic block in the rectangular cavities, the system's syntonic frequency altered. The method of equivalent circuit, the software of high-frequency structure simulator (HFSS) and MAGIC are used to analyse and simulate this device. Initial results show that 20% relative bandwidth, minimum output power 600 MW can be gotten in this frequency agile relativistic magnetron, when operating voltage is 650 kV with 0.1 ns rise time and magnet field of 0.6 T respectively.
