The experimental procedures required to operate windowless photomultiplier detectors as photon counters in the extreme uv (xuv) below wavelengths of about 1300 A are reviewed. The requirements for obtaining a well-defined counting plateau for the counting system under conditions of operation frequently met in laboratory vacuum systems are emphasized. The determination of both the absolute quantum efficiency of the detector and the dynamic range over which the response of the detector varies linearly with the rate of photons is described. The experimental methods used to determine the photometric efficiency of a monochromator and its detection system are also discussed.
回顾了在波长约1300埃以下的极紫外(XUV)波段将无窗光电倍增探测器用作光子计数器所需的实验程序。强调了在实验室真空系统中经常遇到的操作条件下,计数系统获得明确计数平台的要求。描述了探测器绝对量子效率和探测器响应随光子速率线性变化的动态范围的确定方法。还讨论了用于确定单色仪及其检测系统光度效率的实验方法。
