Contribution

It introduces a novel network of spherical TPC detectors for supernova neutrino detection, emphasizing simplicity, stability, and low cost for long-term observation.

Findings

Approximately 1000 events expected from a supernova at 10 kpc

Detector radius of 4 meters with 10 atm Xe gas

Potential for a multi-century supernova detection network

Abstract

The coherent contribution of all neutrons in neutrino nucleus scattering due to the neutral current offers a realistic prospect of detecting supernova neutrinos. As a matter of fact. for a typical supernova at 10 kpc, about 1000 events are expected usinga spherical gaseous detector of radius 4 m andemploying Xe gas at a pressure of 10 Atm. We propose a world wide network of several such simple, stable and low cost supernova detectors with a running time of a few centuries.
