Abstract

Presently, there are several experimental setups dedicated to rare event searches, such as dark matter interactions or double beta decay, in the building or commissioning phases. These experiments often use large mass detectors and have excellent performance in terms of energy resolution, low threshold and extremely low backgrounds. In this paper we show that these setups have the possibility to exploit coherent scattering on nuclei to detect neutrinos from galactic supernova explosions, thus enlarging the number of early detection "observatories" available and helping in the collection of valuable data to perform flavour-independent studies of neutrinos' emission spectra.
