摘要: 针对磁绝缘线高功率微波振荡器(MILO)的静态保真空和重频运行，设计了一种真空度在线测量系统及其组件，优化了常规的测量方法，实现了真空度的实时监测和数据采集。基于30 GW高功率脉冲平台，以硬管化MILO微波源为负载，开展了加电运行条件下微波源内真空度的实时在线测量。实验结果表明：研制的真空在线测量组件具有较强的抗电磁干扰能力，能够准确获得高功率微波源运行过程中的本底真空度及脉冲放气特性。Abstract: In this paper, a real-time vacuum measurement system is designed for the static vacuum maintaining and repetition frequency operation of Magnetically Insulated Transmission Line Oscillator(MILO). By optimizing the conventional vacuum measurement method, this system realizes the real-time monitoring of vacuum and data acquisition. Experiments of real-time vacuum measurement in the MILO were carried out on a 30 GW pulse power driver. Results show that this system has good anti-electromagnetic interference ability. Meanwhile, accurate pressures and pulse deflation characteristics can be well obtained. Under repetition frequency operation, this vacuum measurement system can provide technical support for parameter diagnosis of HPM sources.
