论文摘要
下一代的超高能宇宙射线(UHECR)和非常高的能量中微子观测值将解决这些颗粒在最高能量下极低通量的挑战。 EUSO-SPB2(超级压力气球上的Extreme Universe太空天文台2)旨在准备太空任务以应对这一挑战。 EUSO-SPB2 is equipped with 2 telescopes: the Fluorescence Telescope, which will point downwards and measure fluorescence emission from UHECR air showers with an energy above 2EeV, and the Cherenkov Telescope (CT), which will point towards the Earth's limb and measure direct Cherenkov emission from cosmic rays with energies above 1PeV, verifying the technique. CT指向肢体下方,将搜索由中微子采购的Tau-Lepton衰减产生的Cherenkov发射,并在10PEV能量以上的能量和研究背景上进行此类事件。 EUSO-SPB2任务将在通往空间的多通信天文台的道路上提供开创性的观察和技术里程碑。
The next generation of ultra-high energy cosmic ray (UHECR) and very-high energy neutrino observatories will address the challenge of the extremely low fluxes of these particles at the highest energies. EUSO-SPB2 (Extreme Universe Space Observatory on a Super Pressure Balloon2) is designed to prepare space missions to address this challenge. EUSO-SPB2 is equipped with 2 telescopes: the Fluorescence Telescope, which will point downwards and measure fluorescence emission from UHECR air showers with an energy above 2EeV, and the Cherenkov Telescope (CT), which will point towards the Earth's limb and measure direct Cherenkov emission from cosmic rays with energies above 1PeV, verifying the technique. Pointed below the limb, the CT will search for Cherenkov emission produced by neutrino-sourced tau-lepton decays above 10PeV energies and study backgrounds for such events. The EUSO-SPB2 mission will provide pioneering observations and technical milestones on the path towards a space-based multi-messenger observatory.
