Current accelerator projects will involve the construction and field measurement of up to 10 000 magnets. A statistical has shown that in order to optimize the performance of an accelerator it will be necessary to measure the parameters of field strength, field uniformity and harmonic content of every magnet. If the measurements are performed at the construction site, the magnets which do not meet the required specifications can be repaired immediately. This paper describes a self-contained field measurement and analysis system, based on an IBM microcomputer, which performs all the remote control, data acquisition and data analysis functions automically. The system is of low cost such that each manufacturer can provide field parameters for each magnet as it is completed thus avoiding a logistical problem at the accelerator site.
