Abstract

Next-generation neutrino telescopes with significantly improved sensitivity are required to pinpoint the sources of the diffuse astrophysical neutrino flux detected by IceCube and uncover the century-old puzzle of cosmic ray origins. A detector near the equator will provide a unique viewpoint of the neutrino sky, complementing IceCube and other neutrino telescopes in the Northern Hemisphere. Here we present results from an expedition to the north-eastern region of the South China Sea, in the western Pacific Ocean. A favorable neutrino telescope site was found on an abyssal plain at a depth of $\sim$ 3.5km. At depths below 3km, the sea current speed, water absorption and scattering lengths for Cherenkov light, were measured to be $v_{\mathrm{c}}<$10cm/s, $\lambda_{\mathrm{abs} }\simeq$ 27m and $\lambda_{\mathrm{sca} }\simeq$ 63m, respectively. Accounting for these measurements, we present the design and expected performance of a next-generation neutrino telescope, TRopIcal DEep-sea Neutrino Telescope (TRIDENT). With its advanced photon-detection technology and large dimensions, TRIDENT expects to observe the IceCube steady source candidate NGC 1068 with 5$\sigma$ significance within 1 year of operation. This level of sensitivity will open a new arena for diagnosing the origin of cosmic rays and probing fundamental physics over astronomical baselines., Comment: 34 pages,12 figures.

Abstract

Cosmic rays were first discovered over a century ago, however the origin of their high-energy component remains elusive. Uncovering astrophysical neutrino sources would provide smoking gun evidence for ultrahigh energy cosmic ray production. The IceCube Neutrino Observatory discovered a diffuse astrophysical neutrino flux in 2013 and observed the first compelling evidence for a high-energy neutrino source in 2017. Next-generation telescopes with improved sensitivity are required to resolve the diffuse flux. A detector near the equator will provide a unique viewpoint of the neutrino sky, complementing IceCube and other neutrino telescopes in the Northern Hemisphere. Here we present results from an expedition to the north-eastern region of the South China Sea. A favorable neutrino telescope site was found on an abyssal plain at a depth of $\sim$ 3.5 km. Below 3 km, the sea current speed was measured to be $v_{\mathrm{c}}, Comment: 33 pages,16 figures. Correspondence should be addressed to D. L. Xu (donglianxu@sjtu.edu.cn)
