Off-Axis Injection Simulation for SYLA Storage Ring

Within the framework of the Federal Scientific and Technical Program for the Development of Synchrotron and Neutron Studies and Research Infrastructure, the fourth-generation synchrotron light source is being under development at the National Research Center Kurchatov Institute. The source involves a 6 GeV storage ring and a free electron laser based on a normal conducting linear accelerator, which will also be used as an injector for the storage ring. An injection system is one of the main parts of the storage ring that provide the electron bunch injection into the synchrotron. The injection system should have a high injection efficiency, maintain a high beam quality, minimize the space required to accommodate its components, and ensure repeatability of parameters of its magnetic elements. The injection of electrons with energy of 6 GeV imposes stringent requirements on pulsed kicker magnets because of the short pulse duration (~3 µs) of the high voltage supply. The multiturn horizontal injection has been simulated using an injection system consisting of a septum and four kicker magnets.
