Abstract
In order to characterize the insertion devices at the Advanced Photon Source (APS) more efficiently, a new stretched-coil magnetic field integral measurement system has been developed. The system uses the latest state-of-the-art field-programmable gate array (FPGA) technology to compensate the speed variations of the coil motions. Initial results demonstrated that the system achieves a system measurement reproducibility of 0.15 Gauss centimeter (G-cm) in a field integral measurement of 600 G-cm, probably the world’s best of its kind.
