	For the purpose of realization of single-turn injection and extraction from the NSLS-II booster synchrotron, BINP members created nanosecond non-vacuum ferrite kickers with fronts of pulsed magnetic field of ~ 200 ns, flat-top duration of 300 nsec and its instability of 0.2/1% at most. This paper describes the design of unique kicker magnets with ceramic vacuum chambers with deposited longitudinal strips of titanium nitride (TiN) inside. The paper also presents the results of bench tests of the kickers: oscillograms of current pulse in bus bars, the shape of the pulsed magnetic field, and transverse distribution of the longitudinal field integral in the kicker aperture.

MOPWA027	Pulse Power Supplies for Kicker Magnets of NSLS-2 Booster Ring	720

	A set of identical ferrite kicker modules is utilized for the injection and extraction of the NSLS-2 booster ring. The pulse power supplies of these modules are based on the PFN-thyratron design. The pulse current amplitude of up to 4 kA at 300 ns flat top duration and PFN charging voltage of up to 23 kV were achieved on the extraction pulsers. The pulse to pulse repeatability of the output current waveform was measured and made up to 0.05% (σ) at nominal current for the extraction pulsers. The injection pulsers have a specification on the reverse current overshoot to be less than 0.5% of the amplitude. To fulfill this requirement a single turn saturated choke in the thyratron circuit was used. The design and the test results of the power supplies on NSLS-2 site are presented in the paper.
