Description
The Pierre Auger Observatory's array of surface detectors is being upgraded by adding new detectors and replacing electronics.
The upgrade project, called "AugerPrime," includes the addition of a small PMT to increase the dynamic range for particle counting, a plastic scintillator above each WCD to improve the discrimination between the electromagnetic and muonic shower components, a radio detector to measure radio emission from inclined air showers and a set of underground muon counters to provide additional information on muon content in atmospheric showers.
The new electronics, dubbed Upgraded unified Board or UUB, is designed to acquire all of these additional detectors and includes improved GPS receivers, higher sampling rates, increased dynamic range, greater processing capacity, and improved calibration and monitoring systems. In this talk I will present the UUB design and discuss its performance as observed in the first data from the upgraded array.
