Abstract
The NSLS VUV ring has achieved its design emittances at currents up to 400 mA in one bunch and 385 mA in three bunches. The maximum ring current is thought to be limited by Touschek lifetime with one bunch stored, and by a vertical coupled-bunch instability with three bunches stored. Ion trapping causes vertical tune spread and little else at 750 MeV, but seems to pose more serious problems at 250 MeV.
