摘要
电弧放电效应是高功率微波系统中普遍存在的问题，为了确保微波系统的安全稳定工作，通常需要一种快速且稳定的诊断预警系统对电弧放电效应进行在线监测。利用开源硬件和LabVIEW数据采集软件设计了一套实时监测装置，该装置可以在数十微秒量级以内实现对腔体内电弧放电产生响应，从而达到保护高功率微波腔体的目的。该装置安装在耦合器的探测器室，并采用了一种冗余硬件设计方法来提高系统的稳定性。本文主要讨论该微波腔体电弧放电效应诊断预警系统的设计方案、软硬件架构和性能分析，并给出了该系统的初步实验结果。
Abstract
Background
2
Arc discharge is one of the main issues of high power radio frequency (RF) cavities
which may affect the stable operation of the RF system and requires to be fast detected.
Purpose
2
This paper aims to design a diagnosis and warning system to detect the arc discharge in real-time.
Methods
2
Based on open-source hardware and LabVIEW data acquisition software
this system was built and installed in the detector chamber inside the coupler. A redundant hardware design strategy was employed to improve the stability of the system.
Results
2
Experimental test results showed the response time was of tens of microseconds.
Conclusion
2
Design scheme and implementation proposed in this paper can be referenced for protecting high power microwave cavity.
