Description
Beamline magnets are essential parts of an accelerator system in order to ensure final beam quality on the target. Thus it is necessary to conduct magnetic field measurement and shimming to ensure that ever magnet has sufficient field accuracy. CIAE is vigorously promoting the industrialization of cyclotrons and the promotion of design capabilities for other types of particle accelerator. In order to conform with such tendency, a new set of magnetic field measurement system is designed, which can be easily transferred between point measurement mode and rotation measurement mode. The system consists four axes of motion: 3 translational axis following Cartesian System and 1 rotation axis following axial direction, and the control system is designed to be able to conduct field measurement automatically. For accuracy, field measurement system uses high-precision hall probe and moves in go-stop mode when run in point measurement mode; when it runs in rotation measurement, the system uses induction coil and switch to external trigger mode, allowing users to gain field reading while the probe is rotating.
