Description

Within the FAIR project, SIS18 is planned to be used as an injector and booster to increase the intensity of ion beams. To achieve higher intensities, a two-plane multi-turn injection scheme for SIS18 is being developed at GSI. The new injection system will allow a substantial increase in the number of accumulated turns with high efficiency, significantly reducing beam losses at the electrostatic septum (ES). This paper presents the conceptual design of the two-plane injection system and the results of studies on the expected properties of the U²⁸⁺ beam delivered from the upgraded UNILAC, including its parameters after collimation in the TK transfer line. Furthermore, the paper discusses the design requirements for the injection line and the anticipated performance of the two-plane injection system in SIS18, taking into account the beam optics of the injection line, collimation effects, and overall injection efficiency.
