  We discuss the current status and plans for developing the NSLS-II injector. The latter consists of a 200 MeV linac, a 3-GeV booster, transport lines and the storage ring injection straight section. The system design and installation are complete. Last year we concluded 200-MeV linac commissioning and are planning to commission the 3 GeV booster during summer of 2013.

In this paper, we present a preliminary study on using a Robinson wiggler, a wiggler with transverse gradient, to reduce the horizontal beam emittance of the Hefei Light Source II (HLS-II) storage ring. A proof-of-principle study demonstrates that it is possible to further reduce the horizontal beam emittance by 50\% using a 2-meter long Robinson wiggler installed on a dispersive straight section. This encouraging result suggests a feasible option to significantly improve the HLS-II performance at a relative low cost and without significant modification to its global configuration in the near future.
