Description
The presentation shows a simulation and optimisation of the FCC-ee positron source using a high-temperature superconducting (HTS) solenoid as the matching device to collect positrons downstream of the target. The conventional target scheme composed of simply a single tungsten is used. The target is placed inside the bore of the HTS solenoid to improve the positron yield. The position of the target is optimised. The latest recommended baseline beam parameters are also presented and used in the study. The accepted positron yield at the entrance of the damping
ring has been significantly improved compared with the flux concentrator matching device.
