Abstract Details

2024, Master of Sciences, Case Western Reserve University, Physics.
Ultra high-energy cosmic rays (UHECR) are cosmic rays with energies greater than 1~EeV. The Origin of UHECR has remained a mystery for decades. On Earth we detect UHECR indirectly due to extensive air showers. We use detection on the ground to reconstruct the arrival direction, energy, and composition of UHECR. Auger@TA is a collaboration between the two major observatories for UHECR: the Pierre Auger Observatory (Auger) and the Telescope Array (TA). The main goal for Auger@TA is to conduct an in-situ cross-calibration based on air showers detected using surface detectors from both projects: TA scintillator detectors vs.~Auger Water Cherenkov Detectors (WCD). Auger@TA (Phase 2) consists of a small array of Auger WCD surface detector stations deployed within the existing TA observatory near Delta, Utah. This allows for individual cosmic-ray air shower events to be simultaneously and independently detected and reconstructed by both Auger and TA surface detectors, providing for an event-by-event comparison. In this thesis, we will discuss laboratory experimental work on the fabrication and testing of the photomultiplier tube (PMT) base electronics to be used on each WCD surface detector. These PMT bases have been deployed into the field. We also describe an improved analysis method to calibrate the energy response of Auger@TA WCD using vertical through-going muons, which has been applied to data collected from Auger@TA detectors in the field. This work directly supports the installation and commissioning of Auger@TA which will operate to collect cosmic ray air shower data from 2024 to 2026.
