SPS-II beam injection using a non-linear kicker

SPS-II is the fourth generation electron storage ring in Thailand. The medium-sized ring constructed with a Double- Triple Bend Achromat (DTBA) cell provides low emittance and high capacity for the beamlines. To complement the compact storage ring with DTBA cell, a Non-Linear Kicker (NLK) was chosen for beam injection. This approach not only simplifies the injection system by reducing the number of required kickers but also enhances the overall reliability and efficiency of the injection process. This paper discusses the injection dynamics and optimization strategies associated with implementing the NLK in the SPS-II storage ring. Through comprehensive simulations and analyses, we demonstrate the NLK’s efficacy in achieving high injection efficiency.
