Proton Energy Reconstruction with the MAGIC Experiment — •Alicia Fattorini and Lena Linhoff for the MAGIC collaboration — TU Dortmund, Germany

MAGIC is a stereoscopic telescope system located on Roque de los Muchachos (2200 m a.s.l.) on La Palma, Canary Islands. The two Imaging Air Cherenkov Telescopes (IACTs) were built for the detection of gamma-ray sources at energies between 20 GeV and 100 TeV. The background of measurements with IACTs consists mainly of protons and heavier nuclei such as helium and iron. The signal-to-background ratio is typically 1:10000, leading to large statistics of hadrons. In this work, the energies of the primary protons are estimated. The proton energies are reconstructed with a random forest trained and tested on Monte Carlo simulations of protons. The performance of the energy reconstruction of protons and the instrument response of the telescopes are shown.
