Description
We present the status of the development of a Cherenkov telescope to be flown on an ultra-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 from Wanaka, New Zealand and is a precursor for future space-based missions to detect astrophysical neutrinos. The objectives of this mission are to classify known and unknown sources of background and make the first observation of cosmic rays via Cherenkov technique from suborbital altitude. We also intend to perform target of opportunity searches in response to international multi-messenger alerts and use the Earth-skimming technique to search for Very-High-Energy (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° x 6.4° (Horizontal x Vertical) field of view, that utilizes novel stereo optical system. The camera signals are digitized with a 100 MS/s readout system. In this poster, we report the status of the telescope development and its integration, and discuss the recent field test results.
