利用同步辐射在0.6 ~ 2.0 keV和5 ~ 20 keV的能量范围内对微通道板(mcp)的x射线检测特性进行了研究。微通道板在不饱和脉冲高度分布模式下工作。首次用x射线能量变化连续测量了mcp的电流响应曲线。实验结果表明,在MCP材料的吸收边缘对应的能量处,响应出现了一些不连续的跳跃。在低能范围(hν 5 keV),观察到对θ的弱依赖,这主要归因于x射线通过多个通道的穿透。
The characteristics of microchannel plates (MCPs) for detection of x rays have been investigated using synchrotron radiation in the energy ranges from 0.6 to 2.0 keV and from 5 to 20 keV. Microchannel plates are operated under the condition of an unsaturated pulse‐height distribution mode. The current response curve of MCPs is measured continuously with x‐ray energy variation for the first time. The experimental result of some discontinuous jumps in the response is obtained at the energies corresponding to the absorption edge of the MCP materials. In the low‐energy range (hν 5 keV), a weak dependence on θ is observed, and is attributed mainly to the penetration of x rays through multiple channels.
