Supernova Neutrino Detection
Astronomers expect that every 30 years or so, a massive star in our Galaxy will reach the end of its life. When the core of such a star collapses, it emits nearly all of the gravitational binding energy of a neutron star in the form of neutrinos, some Eb ∼ 3 × 10 53 ergs. Less than 1% of this energy is released in the form of kinetic energy and optically visible radiation. The remainder is radi...
متن کاملSupernova Neutrino Detection in Borexino
We calculated the expected neutrino signal in Borexino from a typical Type II supernova at a distance of 10 kpc. A burst of around 110 events would appear in Borexino within a time interval of about 10 s. Most of these events would come from the reaction channel ν̄e + p → e+ + n, while about 30 events would be induced by the interaction of the supernova neutrino flux on 12C in the liquid scintil...
متن کاملSupernova Neutrino Detection in a liquid Argon TPC
A liquid Argon TPC (ICARUS-like) has the ability to detect neutrino bursts from type-II supernova collapses, via three processes: elastic scattering by electrons from all neutrino species, and νe charged current absorption on Ar with production of excited K and ν̄e charged current absorption on Ar with production of excited Cl. In this paper we have used new calculations in the random phase appr...
متن کاملThe Nuclear Physics of Solar and Super- nova Neutrino Detection
This talk provides a basic introduction for students interested in the responses of detectors to solar, supernova, and other low-energy neutrino sources. Some of this nuclear physics is then applied in a discussion of nucleosynthesis within a Type II supernova, including the r-process and the ν-process.
متن کاملSupernova Neutrino Directionality
In this research project, we try to find out how well we can point to core-collapse supernova by detecting supernova neutrino events in a water detector, and to investigate improvement of the pointing algorithm. A refined model is created of supernova neutrinos in which scattered electron events and 30 times more positron events are generated after a burst of supernova neutrinos has propagated ...
