Conceptual Design of the PANDA Magnet System

Abstract

A magnet system comprising a 2 T superconducting solenoid for a target spectrometer and a large aperture dipole magnet for a forward spectrometer is being developed for the PANDA experiment at GSI. The inner radius of the solenoid coil is 1.1 m. The solenoid is of a split type to provide a warm bore between the coil parts for the target. An energy of 23 MJ is stored in the magnet. The Dipole Magnet will provide a bending momentum of 2 T m. The magnet is of the "H-type" with a water-cooled winding. The paper covers magnetic field and forces calculations as well as strength analysis and description of the magnet system components and their implementation.
