Abstract :
The control system of the insertion devices (IDs) at the Photon Factory storage ring (PF ring) has been renewed in accordance with the high-brilliance project of the PF ring. It consists of a workstation and VME systems, which are linked to dedicated user PCs in the SR experimental hall. Each user of the IDs can change the magnetic gap independently by accessing this workstation during their SR experiment. The closed-orbit affected by changing the gap is corrected using correction magnets system located at both ends of each ID. The vertical fluctuation of the gradients of the photon beam axis is suppressed to less than 2 μrad
