A Very-High-Energy Neutrino Telescope On-board EUSO-SPB2 Mission

We present the status of the development of a Cherenkov telescope onboard 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 from Wanaka, NZ and is a pathfinder for future space-based missions to detect astrophysical neutrinos. The objectives of this mission are to classify the sources of background and make the first observation of Very-High-Energy (VHE) cosmic rays via Cherenkov technique from suborbital altitude. We also intend to perform target of opportunity searches in response to multi-messenger alerts and use the Earth-skimming technique to search for VHE-tau neutrinos below the Earth's limb (E > 10 PeV). The 0.785 m(2) Cherenkov telescope is equipped with a 512-pixel SiPM camera, covering 12.8 degrees x 6.4 degrees (Horizontal x Vertical) field of view. The camera signals are digitized with a 100 MS/s readout system. In this paper, we report the status of the camera development and its performance, and the integration of the telescope.
