TL;DR
This paper proposes a network of spherical gaseous detectors using xenon gas to detect supernova neutrinos via neutral current interactions, potentially enabling long-term, cost-effective supernova monitoring.
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.
