Abstract

The Long-Baseline Neutrino Facility (LBNF) offers an unprecedented intensity for neutrino physics. We discuss a proposal to enhance the LBNF physics programs at Fermilab with the addition of a high-resolution magnetized detector at the near site. The detector is largely based upon reusing an existing superconducting magnet and electromagnetic calorimeter, supplemented with a new low-density straw tube tracker. We also discuss the physics opportunities of the proposed design for the long-baseline oscillation analysis, as well as for precision measurements of (anti)neutrino interactions.
