一种X射线探测器测试仪的开发与应用分析

Development and Application Analysis of a Tester for X-ray Detectors

摘要: 线阵列X射线探测器是X射线安全检查设备的核心部件,X射线探测器测试仪是针对安检设备的基础部件—X射线闪烁探测器的信号增益、本底噪声信号、相邻像素信号串扰等性能指标进行测试而设计的基础部件专用测试仪器。本文简要论述X射线探测器测试仪的功能和关键技术,介绍一种手动微调探测器测试仪的设计。该测试仪已经应用于X射线探测器的测试,文中列出了部分测试结果。

Abstract: The X-ray detector tester is an essential testing device for testing the performance indexes of the linear array X-ray detector, the core component of X-ray security inspection equipment, such as signal gain, background noise signal, and signal crosstalk of adjacent pixels. Its function and key techniques are briefly discussed in this article. And a manual fine tuning tester for X-ray detectors design and manufactured by us is mostly introduced in this article. Moreover, its partial test results to some X-ray detectors are given and analyzed.
