Abstract

A pair of superconducting septum magnets are required to permit hypernuclear physics experiments at JLAB´s Hall A at angles to the incident beam as small as 6 degrees. A cold iron superconducting “C” magnet design has been selected. This magnet has a central field of 4.23 Tesla at a current density of 25,000 Amp/cm2, the stored energy is 0.22 Megajoules and the inductance is 1.0 Henries. The magnet has an effective field length of 0.67 meters, an average gap of 0.25 meters and an average pole width of 0.15 meters. The magnet is currently being fabricated by BWXT Inc. under contract to INFN
