	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.

The NSLS-II linac is a 200 MeV normal conducting linac procured as a turn key system from Research Instruments. The linac and associated transport lines were installed at BNL in the winter of 2012. Commissioning activities started March 26 and lasted for 2.5 months. In this report we discuss the successful commissioning results of the linac, issues encountered, and the remaining work that needs to be accomplished for NSLS-II booster commissioning.

	The booster synchrotron of the NSLS-II light source at Brookhaven National Laboratory (BNL) provides electron beam acceleration from 200 MeV up to 3 GeV in 300 ms. This imposes strict conditions on both accuracy of control and synchronization of ramping Power Supplies (PS). Hardware part of PS controls are based on electronics specially developed at BNL and includes Power Supply Controllers (PSC) and Power Supply Interfaces (PSI). The former represents digital part of hardware and implements low-level logic (generating ramp functions, simple data verification and data acquisition), communication with control system software and PSI. The latter is an analogue part of entire system and it performs generation and acquisition analogue and digital signals by a set of on-board DACs, ADCs and digital inputs/outputs. The PSC and the PSI are connected by digital fibre optic link for electrical decoupling. This paper describes software for the booster synchrotron PSs control which is based on EPICS and includes a specially designed electronics configuration, a set of programs to manage ramp functions and to control different types of power supplies, both pulsed and ramping.

	The NSLS-II is a state of the art 3 GeV synchrotron light source under construction at Brookhaven National Laboratory. Since 2012, the injector system gradually moves to the commissioning stage. It occurs after group people efforts on optics design, equipment specifications, construction and tests, assembly, installation and alignment. It is very important and exciting. To make the commissioning smooth and efficient, an important effort was put on the sub-system integration test to make sure the device function along with utility, timing system and control system, to calibrate diagnostics system and to debug high level application with simulated beam signals and required hardware. In this paper, we report our integration test experience and related control system software development.
