切伦科夫辐射器中发射的光的检测需要对短波长光子具有高灵敏度的快速检测器阵列。光电倍增管是传统的短波长光辐射成像探测器，空间分辨率有限，需要昂贵的抗磁屏蔽。我们报告的性能，一个新的，盖革模式操作，硅微雪崩光电二极管（/spl亩/APD）阵列，设计用于切伦科夫光成像应用。我们解决的问题，光学接口，速度和脉冲光谱可实现这些/spl亩/APD。新的/spl mu/APD阵列为需要二维光映射和单光子灵敏度的应用提供了高灵敏度探测器。这些特性使它成为现代高能物理实验中探测切伦科夫光的一个很有前途的候选者。
The detection of light emitted in Cherenkov radiators requires fast detector arrays with high sensitivity to short wavelength photons. Photomultiplier tubes, the traditional imaging detectors for short wavelength optical radiation, have limited spatial resolution and require expensive anti-magnetic shielding. We report on the performance of a new, Geiger mode operated, Si micro-avalanche photodiode (/spl mu/APD) array, designed for Cherenkov light imaging applications. We address issues of optical interfacing, speed, and pulse spectra achievable with these /spl mu/APDs. The new /spl mu/APD array provides a high sensitivity detector for applications requiring two dimensional light mapping with single photon sensitivity. These features make it a promising candidate for the detection of Cherenkov light in modern high energy physics experiments.
