Description
We propose a concept for a e+ source based on high energy e- beams incident on conical converter targets, in pursuit of its implementation in future lepton colliders such as FCC-ee. Two conical target solutions were optimized for a state-of-the-art capture system based on a high-temperature superconducting solenoid, allowing for a full target immersion in a 12.7 T peak field. According to simulation studies, conical targets would increase by up to 70% the e+ yield accepted by the FCC-ee damping ring, including the detrimental impact of their mechanical interface and cooling pipes. A thermo-mechanical study of 2 conical targets and their supports is also presented, using the baseline parameters of the FCC-ee injector linac, as well as a mechanical integration concept for P$^3$, the future FCC-ee e+ source test facility.
