摘要:
针对带防离子反馈膜的微通道板(MCP)普遍存在的C污染现象,开展了真空热处理、紫外臭氧辐照及氢气热处理试验,对各个试验结果进行了MCP电性能测试及俄歇电子能谱(AES)研究,着重分析了MCP表面C含量及MCP性能随不同试验方法的变化趋势。试验结果表明,C含量的降低对MCP性能的提升具有显著作用,真空热处理对C的分解作用甚微,紫外臭氧辐照及氢气热处理均可以较为彻底地去除MCP表面C污染,并且氢气热处理对MCP增益性能的提升作用显著,效率最高。
Abstract:
To investigate the common C pollution phenomenon of the microchannel plate (MCP) with an ion barrier film, we conducted vacuum heating, ultraviolet irradiation, and hydrogen heating tests. Auger electron spectroscopy and MCP electrical performance test are performed on each test result. Furthermore, the trends of MCP C content and MCP performance are analyzed using different methods. The analysis results show that the reduction in C content significantly improved MCP performance. The vacuum heating process does not significantly affect the decomposition of C; however, the UV irradiation and hydrogen heating processes can completely remove MCP C pollution. Finally, hydrogen heating significantly improved the MCP gain performance and resulted in the highest efficiency.
