Research Topic

Energy Scale of the Pierre Auger Observatory Supervisor: Dr. Michael Unger Referees: Prof. Dr. Ralph Engel Starting date: September 2020 The project is divided into two parts: data analysis and calibration. The first part aims to develop new and improved ways for determining the hybrid energy spectrum of cosmic rays. The hybrid spectrum combines the calorimetric measurements by the fluorescence detectors (FD) with the measurements by the surface detector (SD) of particle showers in the atmosphere induced by cosmic rays. Due to high statistics, most event selection criteria and environmental influences on detection capabilities and reconstruction parameters can now be investigated using measured data and not just simulated ones; This enables improved possibilities for determining the energy spectrum. The second part aims to determine the absolute calibration of the telescopes of the FD. This will be achieved by a measurement of the light collection efficiency and the point-spread function of the telescopes. These topics will be addressed by illuminating the telescope optics with a Lambertian and directed light source. |
