Abstract

The 190-m-circumference South Hall Ring (SHR) and Injection Line contain 94 quadrupoles for which the design position tolerances are +or-100 mu m, transverse and vertical. About half of the error budget on this tolerance will be used in fiducialization, the relating of the magnetic axes to the positions of survey targets fixed to the magnet. The system being developed uses the SLAC Industrial Measurement System (SIMS) while the magnetic properties are being measured on a harmonic analyzer. The usual step of relating the magnetic axes to the mechanical axes is bypassed in this system, but this relationship will be measured for a subset of magnets as a check of systematics. Results of the fiducialization of over 20 quadrupoles are presented.<>
