The origin of cosmic rays has remained an enduring mystery for over a century, challenging scientists to uncover the processes and sources behind these highly energetic particles. High-energy neutrinos, with their ability to travel vast distances unaffected by magnetic fields or matter, have emerged as indispensable tools for probing the origins of cosmic rays, offering unique insights into their production mechanisms and astrophysical sources. The proposed High-energy Underwater Neutrino Telescope (HUNT) with an instrumented volume around 30km' aims to detect Galactic and extragalactic high-energy neutrino sources in a short period. Especially, HUNT will have the ability to provide evidence for high-energy neutrinos.
