We describe the procedures used by the Fermilab Magnet Test Facility (MTF) to perform tests of dipoles to be installed in the beam lines of the Loma Linda University Medical Center Proton Therapy Facility. The dipoles were manufactured in two styles, one style having a 45/spl deg/ bending angle and the other a 135/spl deg/ bending angle. The tests included magnetic field measurements using a Hall probe and the measurement of coil temperatures, voltages, and water flow rates. The probe was mounted on a movable cart which could be wheeled along the magnet beam pipe; we mounted extensions onto each end of the beam pipe to allow for the probe to measure the magnet end fields. The probe was also mounted at varying transverse positions on the cart to allow for field shape measurements, from which body quadrupole and sextupole coefficients were determined. A longitudinal sampling of the field down the entire length of the magnet allowed us to measure the total integrated field of each magnet. Hall probe measurements were controlled by a C program running on a Unix workstation. >
