The Extreme Universe Space Observatory on a Super-Pressure Balloon II Mission: Simulations
Abstract
The Extreme Universe Space Observatory Super-Pressure Balloon II (EUSO-SPB2) long-duration balloon-based cosmic-ray experiment is in preparation. A science payload of two telescopes will measure ultra-high energy cosmic rays (UHECRs, EeV scale) via fluorescence and high-energy cosmic rays (PeV scale) via direct Cherenkov radiation. In addition, the Cherenkov telescope will measure the background for future neutrino observations from a space-based experiment, such as the Probe of Extreme Multi-Messenger Astrophysics (POEMMA) mission. To establish an expected event rate for the fluorescence telescope, extensive air showers and the response of the detector to these showers have been simulated. From these simulations, expected triggered event and reconstructable event rates are being estimated. Finally, the effects of different telescope elevation angles are being studied to maximize the number of reconstructable UHECRs as a function of energy.
