A new Helmholtz Coil magnet measurement system has been developed at the Advanced Phone Source (APS) to characterize and sort the insertion device permanent magnets. The system uses the latest state-of-the-art field programmable gate array (FPGA) technology to compensate the speed variations of the magnet motion. Initial results demonstrate that the system achieves a measurement precision better than 0.001 ampere-meters squared (A·m2) in a permanent magnet moment measurement of 32 A·m2, probably the world's best precision of its kind.
