This paper describes a magnetic modulator which was designed for second generation use in the Proton Storage Ring at the Los Alamos Meson Physics Facility. The three stage machine delivered a 25 kV, 100 nanosecond pulse to a 3 ohm load a pulse repetition rates of up to 1 kHz. A principle function of this system was to serve as a test bed for the measurement of energy losses in magnetic switches. The magnetic switch cores were built from materials of two different alloys, and were tested in both as-cast and annealed states. The performance data acquired indicate that annealing of the core material reduces energy loss by up to a factor of five and that, as expected, losses are lower in the higher resistivity materials.
