The characterization of PMTs for the AugerPrime Upgrade of the Pierre Auger Observatory* — •Simon Strotmann and Julian Rautenberg for the Pierre Auger collaboration — Bergische Universität Wuppertal, Gaußstr. 20, 42119 Wuppertal
The Surface Detector (SD) of the Pierre Auger Observatory will be upgraded through the addition of a 4 m2 scintillator detector on top of each station to further improve the sensitivity of the surface array.
A PMT with expected high linearity was chosen in order to meet the requirements of measuring the scintillator’s signals over a high dynamic range.
A batch test facility, built to verify that the gain and linearity requirements for operation in the field are met by each PMT, will be presented.
The validation of the test facility on the first 80 PMTs recieved as well as the progress on the characterization of the remaining PMTs for the upgrade as well as additional measurements of the spectral and spatial quantum efficiency of selected PMTs will be shown.
