TI - NSLS-II Storage Ring Injection Optimization J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - The National Synchrotron Light Source II (NSLS-II) is a state of the art 3 GeV third generation light source at Brookhaven National Laboratory. The SR is designed to work in top-off injection mode. The injection straight includes a septum and four fast kicker magnets with independent amplitude and timing control. The beam injection is designed as 9.5 mm off-axis in x plane and on-axis injection in y plane. To capture the injected beam within the SR acceptance for high injection efficiency, it requires 6-D phase space match. Besides that, the fast kickers formed local bump is also required to be locally to minimize the injected beam extra betatron oscillation and keep the stored beam disturbance within the specification, 10% beam size to minimize the injection transient. This paper will present the beam results before and after optimization.
