Supernova neutrino detection via coherent scattering

Development of large mass detectors for low-energy neutrinos and dark matter may allow supernova detection via neutrino-nucleus elastic scattering. The Spherical Proportional Counter, recently developed, allows to instrument large target masses with good energy resolution and sub-keV energy threshold. This detector filled with a high pressure and high Z noble gas, can be employed to detect typical supernova neutrinos in our galaxy. Here we provide feasible measured signal rates and describe further developments optimizing the electric field configuration around the central electrode of the detector
