Abstract :
Magnetic measurements performed on 12-pole trim magnets, including Hall-probe measurements to verify the symmetry of the field and rotating coil measurements to map the multipoles, are described. The rotating coil measurements were carried out using an HP dynamic signal analyzer. Excited as a quadrupole the dominant error multipole is the 20th pole, and exited as a sextupole the dominant error multipole is the 18th pole. Reasonable agreement was found between the Hall-probe measurements and the rotating coil measurements.<>
