皮尔俄歇天文台荧光探测器的绝对校准在望远镜孔径处使用 375 nm 光源。这种端到端技术考虑了单次测量中所有探测器组件的综合效应。在 320、337、355、380 和 405 nm 波长下测量了相对响应，定义了已归一化为绝对校准的光谱响应曲线。每晚数据采集之前和之后都会对光电管进行相对校准。这种相对校准用于跟踪探测器响应的短期和长期变化。一些光电管的校准交叉检查是使用独立的激光技术进行的。讨论了总体不确定性、当前结果和未来计划。
Absolute calibration of the Pierre Auger Observatory fluorescence detectors uses a 375 nm light source at the telescope aperture. This end-to-end technique accounts for the combined effects of all detector components in a single measurement. The relative response has been measured at wavelengths of 320, 337, 355, 380 and 405 nm, defining a spectral response curve which has been normalized to the absolute calibration. Before and after each night of data taking a relative calibration of the phototubes is performed. This relative calibration is used to track both short and long term changes in the detector's response. A cross check of the calibration in some phototubes is performed using an independent laser technique. Overall uncertainties, current results and future plans are discussed.
