A system is considered where an unloaded ac generator is triggered to pulse an inductive load in a decaying train of oscillations. This is suitable for pulsing AGS ring multipoles where the required magnetic energy is a few kilojoules. The decaying oscillations serve to demagnetize the load. Since the output impedance of the generator is low and the magnetic coupling coefficient between stator and rotor is close to unity the short circuit currents are high and a significant amount of reactive energy is available for the load magnet.
