Design, fabrication and experimental results of a multi-purpose Panofsky magnet

A fast, flexible magnet system, consisting of Panofsky style ferrite picture frame magnet and pulsed power supply has been developed. The magnet specifications are 8 cm × 8 cm aperture, 23 cm length, 500 A pulsed/160 A DC, and a 1 μs rise time. Designed for general accelerator physics studies, the magnet may be quickly converted from dipole to quadrupole by change the winding end terminations. In the quadrupole configuration, a field gradient of 0.5 T/m has been achieved at 500 A.
