Strip-line kicker and fast pulser R&D for the HEPS on-axis injection system
2019
Abstract The HEPS plans to adopt on-axis injection scheme because the dynamic aperture of machine is not large enough for off-axis injection for its baseline 7BA lattice design. A couple sets of strip-line kicker and fast pulser of ± 15 kV amplitude, 15 ns pulse bottom width are needed for bunch spacing of 10 ns to minimize perturbation on adjacent bunches. To achieve these requirement, a multifaceted R&D program including the strip-line kicker and HV pulser, was initiated last 2 years. So far, the prototype development of a 750 mm long strip-line kicker and a DSRD pulser was completed and the preliminary test results show they can meet the baseline requirement of the HEPS.
