Toroidal magnetized iron neutrino detector for a neutrino factory

Abstract

A neutrino factory has unparalleled physics reach for the discovery and measurement of CP violation in the neutrino sector. A far detector for a neutrino factory must have good charge identification with excellent background rejection and a large mass. An elegant solution is to construct a magnetized iron neutrino detector (MIND) along the lines of MINOS, where iron plates provide a toroidal magnetic field and scintillator planes provide 3D space points. In this paper, the current status of a simulation of a toroidal MIND for a neutrino factory is discussed in light of the recent measurements of large θ_{13}. The response and performance using the 10 GeV neutrino factory configuration are presented. It is shown that this setup has equivalent δ_{CP} reach to a MIND with a dipole field and is sensitive to the discovery of CP violation over 85% of the values of δ_{CP}.
