	The National Synchrotron Light Source II is a third generation light source under construction at Brookhaven National Laboratory. The project includes a highly optimized 3 GeV electron storage ring, linac pre-injector and full-energy injector-synchrotron. Budker Institute of Nuclear Physics build booster for NSLS-II. The booster should accelerate the electron beam continuously and reliably from a minimum 170 MeV injection energy to a maximum energy of 3.15 GeV and average beam current of 20 mA. The booster shall be capable of multi-bunch and single bunch operation. Pre-comissioning test results of booster components and system are reviewed.

	Budker Institute has designed and delivered Booster for NSLSII project including vacuum system, magnet system, diagnostics and power supplies. Dipole power supplies were directly delivered to BNL by sub-contractor (Danfysik, Denmark). To test dipole magnets on factory side, at BINP, it was decided to design and construct a high current ramping mode power supply. The designed power supply can operate with the reactive output power up to 150kVA and output current up to 900A at 2Hz ramping mode. The absolute accuracy achieved is better than 100ppm for the injection and extraction flats and better than 500ppm for the ramps.

	Power system for quadrupole magnets of NSLS-II 3 GeV booster is designed, manufactured and tested in BINP, Russia. The power system consists of 2 parts. The first part is a charging source with a capacitance bank at output. And the second part consists of 3 current sources powered by a capacitance bank. The charging source output voltage is up to 180 V, peak power is 40 kW and average power is 20 kW. Capacitance bank has a 120 kVA storage energy. The second part contains 3 independent current sources with up to 180 A output current each. This report considers the details of current sources design, their parameters and results of inspection test in BINP. Finally, the first results of injection and extraction section commissioning at BNL site are reported.

	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.

The dipoles of the Booster have quadrupole and sextupole components and should create high quality of field ± 2·10^-4 in region ± 2 cm. Magnets should provide performance of booster for energy from 170 MeV to 3.15 GeV with 2 Hz frequency. This report considers ramped magnetic measurement of NSLS-II Booster Dipoles.
