The EUSO-SPB2 Cherenkov Telescope, Performance of Camera

ORAL

Abstract

Recently detected high-energy neutrinos by IceCube have given us an exciting new tool to help us understand how cosmic-ray sources accelerate particles to the highest energies and has strengthened interest in measuring the neutrino flux at even higher energies. However, detecting ultrahigh-energy (UHE) neutrinos is challenging because fluxes are low, and the interaction cross-sections are minute. We are developing a Cherenkov telescope to detect Earth-skimming UHE neutrinos from a long-duration balloon flight. It will fly aboard the Extreme Universe Space Observatory Super Pressure Balloon 2 (EUSO-SPB2) a precursor to the proposed Probe of Extreme Multi-Messenger Astrophysics (POEMMA) mission. I will present the status of the Cherenkov telescope camera development and supporting laboratory measurements combined with simulations that demonstrate the performance of the Cherenkov camera.
