Performance analysis of new PMTs and light guide systems at the Fluorescence Detector of the Pierre Auger Observatory — •Urs Große-Rhode for the Pierre Auger collaboration — Bergische Universität Wuppertal, Gaußstraße 20, 42119 Wuppertal, Deutschland

The Fluorescence Telescopes at the Pierre Auger Observatory are used to measure the fluorescence light produced by extensive air showers. Each camera of the telescopes consists of 440 PMTs in the focal plane of a 12m* mirror. To study the performance of a new generation of PMTs, one camera has been partially equipped with two new PMT types and an new light guide system. Different PMT types and their performances will be compared. The analysis uses a reference calibration executed at the camera and laser shots which are fired into the atmosphere at low inclination passing by the telescopes. Also the recently launched Aeolus satellite introduced a new opportunity, providing laser shots into the Observatorys field of view, which trigger the Fluorescence Telescopes. An overview of the used methods for the fluorescence detectors performance analysis as well as results from the aeolus analysis will be presented. *Gefördert durch die BMBF Verbundforschung Astroteilchenphysik(Vorhaben 05A17PX1)
