Abstract / Description of output
OMNIS, the Observatory for Multiflavor NeutrInos from Supernovae will
consist of 8 kT of lead and 4 kT of iron which, when irradiated by
neutrinos from a supernova, will produce secondary neutrons. Detection
of the neutrons in gadolinium loaded liquid scintillators will then
signal the arrival of the supernova neutrinos. A supernova at the center
of the Galaxy, will produce about 2000 events in OMNIS, mostly from
neutral current interactions, thus providing statistically significant
tests of the energies and emission time profiles of core-collapse
supernova models. Additionally, OMNIS' combination of lead and iron
modules gives it sensitivity to several neutrino oscillation scenarios,
especially the type ν_μ/τ rightarrow ν_e. Its intrinsic
timing capability, better than 1 ms, gives it the capability to measure
neutrino mass from the time-of-flight shifts in the luminosity curves of
the different neutrino flavors, to about 20 eV/c^2. OMNIS will also be
able to detect differences in the luminosity cutoffs of the different
flavors in the event of a fairly prompt collapse to a black hole, which
might allow charting out of the neutrinospheres and other diagnostics,
and a better measurement of neutrino mass ( ~3 eV/c^2).
