Development of Microchannel Plate Delay Line X-ray Detectors

研制了一种微通道板延迟线x射线探测系统。这些探测器将具有高精度、高分辨率、大面积和高计数率的能力。该探测器将是测量具有非常大的单位细胞的蛋白质晶体的理想选择，并且将非常适合于多波长异常色散测量。探测器将由一个薄x射线闪烁体、一个半透明光电阴极、一对微通道板和正交延迟线阳极组成。对大尺寸微通道板的延迟线读出进行了研究，并对不同板进行了比较。该检测系统一旦开发出来，将加强对结构生物学的研究。

A microchannel plate delay line X-ray detector system will be developed. These detectors will have high accuracy, high resolution, large area, and large count rate capability. The detectors would be ideal for measurements on protein crystals with very large unit cells, and will be well suited for multiwavelength anomalous dispersion measurements. The detector will consist of a thin X-ray scintillator, a semi- transparent photocathode, a pair of microchannel plates, and orthogonal delay line anodes. Delay line readout of large size microchannel plates will be studied, and different plates will be compared. The detector system, once developed, will enhance efforts in structural biology.
