Abstract :
Five different types of superferric quadrupoles are being built for the A1900 Fragment Separator at the NSCL. At least one of each type has been built and tested in an open helium vessel. Quench behavior was recorded and analyzed. Results were compared to calculated quantities such as internal voltages. The measured internal voltages were always less than those calculated with any set of reasonable parameters. All magnets exhibited some training, but every one met or exceeded the required maximum gradients.
