26 Aug 2019 | Abstract: | The Compact Material Irradiation Facility (CMIF) in China is a current
project that will provide a compact deuteron-beryllium neutron source. The
target of this facility will be an intense and compact Isotope Decay-At-Rest
(IsoDAR) neutrino source. In this paper, we propose a neutrino experiment using
CMIF as the neutrino source and calculate its sensitivity to sterile neutrinos.
With a $50, ext{MeV}$, $10, ext{mA}$ deuteron beam impinging upon a thin
beryllium target of a thickness $2$ $
m g/cm^2$, the electron antineutrino
production rate can be up to $2.0 imes 0^{19}$ per day. When paired with an 80
ton liquid scintillator detector to study short baseline electron antineutrino
disappearance, the inverse beta decay (IBD) event rate is large enough to
investigate the parameter ranges of interest for neutrino anomalies. Our
sensitivity analysis shows that a short baseline experiment at this platform
will provide a very competitive sterile neutrino search, especially in the
high-$Delta m^2$ region ($Delta m^2 >10, ext{eV}^2$). | Source: | arXiv, 1908.9787 | Services: | Forum | Review | PDF | Favorites |
