Abstract
A test pancake magnet, equipped with a persistent superconducting switch, w as fabricated with B-2233/Ag-Mg tape, The magnet was operated in persistent mode at 20 and 77 Ii For large operating currents that forces the magnet t o operate in the flux flow range, the field decays is exponentially with ti me, A simple circuit model is used to compute field decay time constants, I t was also found that Pb-Sn solder joints are unsuitable far persistent mod e operation.
