标题： Calibration of the Pierre Auger fluorescence detector

摘要： 空气荧光探测器（FD）的绝对校准是正确确定探测到的宇宙射线能量的重要因素。 绝对校准将给定波长的光子通量与FD数据采集系统记录的电子信号联系起来。 对于Auger FD，主要的绝对校准方法使用一个扩散表面，放置在望远镜孔径前方，以已知的光信号均匀照亮望远镜视场。 这个单波长测量（375纳米）将在几个月的时间间隔内进行，直到确定望远镜的稳定性。 校准的相对波长依赖性通过独立测量来确定。 单一波长的绝对校准误差估计小于10％。 还使用了另外两种绝对校准方法，以提供对主要测量的独立验证。 通过相对校准系统每晚监测校准随时间的稳定性。 本文将描述Auger空气荧光观测站使用的绝对和相对校准方法。 还将展示Auger工程阵列望远镜校准的结果。 显示英文摘要

摘要： The absolute calibration of an air fluorescence detector (FD) is an important element in correctly determining the energy of detected cosmic rays. The absolute calibration relates the flux of photons of a given wavelength at the detector aperture to the electronic signal recorded by the FD data acquisition system. For the Auger FDs, the primary absolute calibration method uses a diffusive surface which is placed in front of a telescope aperture to uniformly illuminate the telescope field of view with a known light signal. This single-wavelength measurement (375 nm) will be made at intervals of several months until the stability of the telescopes is determined. The relative wavelength dependence of the calibration is determined through independent measurements. The error in absolute calibration at a single wavelength is estimated to be less than 10%. Two other absolute calibration methods are used to provide an independent verification of the primary measurement. The stability of the calibration with time is monitored nightly by a relative calibration system. In this paper we will provide descriptions of the absolute and relative calibration methods used by the Auger air fluorescence observatory. Results from the calibration of the Auger Engineering Array telescopes will also be presented.
