The obstacles, we can imagine, include the magnet hysteresis effect and some environmental effects. To minimize hysteresis effect, we cycle the magnets and it was proved working properly. On the other hand, from the point of long-term operation, we are not yet satisfied with the reproducibilities given by the same set of magnet currents and the machine needs additional tuning processes. In this paper, the experience of NSLS-II operation and studies are presented.
