Abstract :
A precise rotating coil measurement system (RCS) is developed to characterize the magnetic field quality of the quadrupole (QM) and sextupole (SM) magnets in the Taiwan photon source (TPS). A measurement bench is designed to install the magnets easily and mount the rotating coil unit with high reproducibility. The fiberglass reinforced epoxy (FRP) measurement unit (F-unit) exhibits a large sag and mechanical error while it is 880 mm long. Therefore, a new graphite measurement unit (G-unit) with a printed circuit coil is adopted to reduce these errors. The rotating coil design and testing using a QM are also described.
