SLC ARC transport system-AG-magnet measurement and performance

This paper describes the design, construction, and operation of devices used to rapidly measure the mechanical and magnetic properties of some 950 Alternate gradient magnets1 used in the arc system of the Stanford Linear Collider. The problems of dealing with the measurement of the transverse dimensions to within minute (0.0001 in) resolution of objects that are 8 ft long are discussed. Early results from the production runs of these magnets are presented.
