Title: Conceptual Design of DUNE Near Detector Superconducting Magnet System

Abstract

The Deep Underground Neutrino Experiment (DUNE) has formed a near detector design group (NDDG) tasked with de-livering a CDR by the end of 2019. The DUNE Near Detectors will be housed in an underground hall on the Fermilab site. The two main detector systems are a liquid argon detector and a high-pres-sure gas time projection chamber (HPgTPC). The HPgTPC re-quires a magnet that generates a 0.5 T solenoidal magnetic field in a large volume of 6 m diameter, and 5 m length. In this paper, we present a superconducting magnet system design. We investi-gated: an open air core magnet with three coils, and a five coils system having two active fringe field shielding coils. Coils positions were optimized to obtain the specified field homogeneity in the magnet good field region, while minimizing the Lorentz forces and the superconductor volume. We discuss the magnetic, mechanical, and thermal conceptual designs.
