Overview of Cherenkov Telescope on-board EUSO-SPB2 for the Detection of Very-High-Energy Neutrinos

We present the status of the development of a Cherenkov telescope to be flown on a long-duration balloon flight, the Extreme Universe Space Observatory Super Pressure Balloon 2 (EUSO-SPB2).EUSO-SPB2 is an approved NASA balloon mission that is planned to fly in 2023 and is a precursor of the Probe of Extreme Multi-Messenger Astrophysics (POEMMA), a candidate for an Astrophysics probe-class mission.The purpose of the Cherenkov telescope on-board EUSO-SPB2 is to classify known and unknown sources of backgrounds for future space-based neutrino detectors.Furthermore, we will use the Earth-skimming technique to search for Very-High-Energy (VHE) tau neutrinos below the limb (E > 10 PeV) and observe air showers from cosmic rays above the limb.The 0.785 2 Cherenkov telescope is equipped with a 512-pixel SiPM camera covering a 12.8°x 6.4°(Horizontal × Vertical) field of view.The camera signals are digitized with a 100 MS/s readout system.In this paper, we discuss the status of the telescope development, the camera integration, and simulation studies of the camera response.
