Description
The Korea-4GSR project is developing a fourth-generation storage ring light source that employs a linear accelerator (LINAC) and a booster ring as injector systems. In the LINAC, electron bunches are produced by a UV laser in the photocathode RF gun and subsequently accelerated to 200 MeV. To achieve this target energy, four accelerating structures are utilized, with a solenoid magnet positioned near the gun to provide initial beam focusing. To ensure efficient beam matching into the booster ring, nine quadrupole magnets are arranged downstream of the first accelerating structure. RF power is delivered by two klystron–modulator systems, each exceeding 70 MW in peak power and independently stabilized through dedicated LLRF–SSA feedback control. The RF power supplied to the gun is further conditioned by a waveguide-based phase shifter, circulator, and attenuator, which are manually adjusted prior to operation and fixed during beam delivery. Detailed system parameters and performance characteristics will be presented.
