中文摘要
小行星9361738 提出了一种高速、高灵敏度的雪崩光电二极管(ADP)阵列,以满足高能物理实验对探测器的严格要求,如为现有和拟议中的粒子物理探测器设计的中心跟踪器、顶点探测器和量热计。 这些探测器将具有前所未有的性能特性,可用作在再生塑料纤维中产生的非常低的光水平的读出器,这些光水平是由带电粒子以非常高的再循环率相互作用引起的。 所采取的方法将是修改现有的APD设计,以产生一种暗电流较低的设备,增加在短波长的灵敏度,更快的周期时间时,在单光子盖革模式操作。 考虑了APD对有源猝灭电路的适应性。 构建高增益设备,满足检测器的比例模式操作的需要,如高动态范围量热测量所需的。 在这项工作中收集的数据将用于生产APD阵列,该阵列具有所需的特性组合,可用于现代探测器(如Fermilab的D 0和CERN的L3)所设想的高速,低亮度应用。 现代粒子物理设施将需要数百万个探测器。 这本身就是一个巨大的市场。 此外,这些改进的APD将在工业应用中找到许多其他用途,例如医学成像和研究应用。 *** v S t $ $ $ ( F / / 1件 Symbol Arial 5 Cash New " H fB %fB % C R:\WW20USER\ABSTRACT.DOT 丹尼斯亨利丹尼斯亨利
英文摘要
9361738 Entine A high speed, high sensitivity avalanche photodiode (ADP) array is proposed to meet the stringent requirements of detectors for high energy physics experiments such as the central tracker vertex detector and calorimeters which are being designed for existing and proposed particle physics detectors. These detectors will have unprecedented performance characteristics to be used as readouts for the very low light levels produced in scintillating plastic fibers which result from charged particle interactions at very high recycle rates. The approach taken will be to modify existing APD designs to yield a device with lower dark current, increased sensitivity at short wavelengths, and faster cycle times when operated in the single photon Geiger mode. Consideration was given to adaptability of the APD to active quenching circuitry. Constructing high gain devices that fulfill detector needs for proportional mode operation such as those required for high dynamic range calorimetry measurements will also be investigated. The data gathered during this work will be used to produce an APD array with the required combination of characteristics to be used in high speed, low light level applications envisioned at modern detectors such as the D0 at Fermilab and L3 at CERN. Millions of detectors will be needed for modern particle physics facilities. This alone is a large market. Also, these improved APD's will find numerous other uses in industrial applications, such as medical imaging, and research applications. *** v s t $ $ $ ( F / / 1 Courier Symbol & Arial 5 Courier New " h fB %fB % C R:\WW20USER\ABSTRACT.DOT Denise Henry Denise Henry
