标题： Performance of the Pierre Auger Fluorescence Detector and Analysis of well recontructed events

摘要： 皮埃尔·奥格天文台旨在阐明超高能宇宙射线的起源和性质，采用混合探测技术。 2001年至2002年期间，两个探测器的原型版本（即所谓的工程阵列）进行了首次数据采集运行，使合作组能够评估两种探测器系统的性能并制定分析策略。 在此贡献中，在简要描述系统之后，我们将报告有关荧光探测器（FD）原型行为的一些结果。 将介绍性能研究，例如噪声、灵敏度和占空比的测量。 我们将展示所选空气簇射的初步分析结果。 该分析仅使用来自FD的信息，包括簇射几何结构和纵向剖面的重建。 显示英文摘要

摘要： The Pierre Auger Observatory is designed to elucidate the origin and nature of Ultra High Energy Cosmic Rays using a hybrid detection technique. A first run of data taking with a prototype version of both detectors (the so called Engineering Array) took place in 2001-2002, allowing the Collaboration to evaluate the performance of the two detector systems and to approach an analysis strategy. In this contribution, after a brief description of the system, we will report some results on the behavior of the Fluorescence Detector (FD) Prototype. Performance studies, such as measurements of noise, sensitivity and duty cycle, will be presented. We will illustrate a preliminary analysis of selected air showers. This analysis is performed using exclusively the information from the FD, and includes reconstruction of the shower geometry and of the longitudinal profile
