Description
Two-plane multiturn injection is planned for SIS18 to enable the delivery of high-intensity heavy-ion beams, which will subsequently be accelerated and extracted toward SIS100 at a repetition rate of 2.7 Hz. To accommodate this new injection scenario, the existing SIS18 injection line must be redesigned to allow simultaneous injection into both the horizontal and vertical planes of the synchrotron. Ion-optical studies have been performed to evaluate the expected performance of the upgraded injection system, and the results are presented in this paper. The simulations demonstrate that the injection efficiency strongly depends on the emittance and transverse beam distribution of the beam delivered from UNILAC. Furthermore, a mismatch between the injected orbit and the equilibrium orbit defined by the transfer line optics leads to additional efficiency degradation. The paper discusses the impact of beam collimation in the transfer line, analyzes the sensitivity of the injection efficiency to various mismatch scenarios, and provides guidance for optimizing the two-plane multiturn injection process for SIS18.
