“…The extremely small emittance of the storage ring leads to a small dynamic aperture which makes it difficult for the injection, so novel on-axis swap-out injection scheme in the transverse plane and the longitudinal accumulation injection scheme are considered [3]. For the injector, two candidate options are being compared, i.e., booster with pre-injector Linac and a full energy Linac [4]. The injector option of a low energy Linac and a booster has been adopted by many synchrotron photon facilities [5][6][7][8][9][10] due to its robustness and lower cost, so it is the primary option.…”

The Southern Advanced Photon Source (SAPS) is a planned fourth-generation synchrotron radiation facility featuring a low-emittance storage ring. For the H-7BA lattice design, the dynamic aperture is significantly smaller than the physical aperture, necessitating the use of a strip-line kicker based on an on-axis injection scheme. To minimize interference from the pulser on adjacent beams, a nanosecond pulser with stringent rise and fall time requirements is essential. A prototype pulser, based on a semiconductor opening switch, was developed to meet these demands. A nonlinear transmission line loaded with ferrite was utilized for pulse shaping, yielding favorable results. The prototype generated a pulse at a 50 Ω load with a rise time (10%–90%) of 2.4 ns, a fall time (90%–10%) of 3.9 ns, a pulse width (10%–10%) of 7.8 ns, and an amplitude of 19.8 kV. This paper presents the detailed design, optimization, and performance evaluation of the pulser.
