In this paper, we present the simulation and optimisation of the FCC-ee positron source, where a high-temperature superconducting (HTS) solenoid is used as the matching device to collect positrons from the target. The "conventional" target scheme is used which simply consists of amorphous tungsten. [...]

Overall Injection Strategy for FCC-ee
/ Ogur, Salim (CERN) ; Aiba, Masamitsu (PSI, Villigen) ; Antoniou, Fanouria (CERN) ; Barnyakov, Alexey (Novosibirsk, IYF) ; Chaikovska, Iryna (Orsay, LAL) ; Charles, Tessa (CERN) ; Chehab, Robert (Orsay, LAL) ; Etisken, Ozgur (Ankara U.) ; Furukawa, Kazuro (KEK, Tsukuba) ; Härer, Bastian (CERN) et al.
The Future Circular electron-positron Collider (FCC-ee) requires fast cycling injectors with very low extraction emittances to provide and maintain extreme luminosities at center of mass energy varying between 91.2-385 GeV in the collider. For this reason, the whole injector complex table is prepared by putting into consideration the minimum fill time from scratch, bootstrapping, transmission efficiency as well as store time of the beams in synchrotrons to approach equilibrium emittances.

The FCC-ee is a high-luminosity, high-precision circular collider to be constructed in a new 100 km tunnel in the Geneva area. The physics case is well established and the FCC-ee operation is foreseen at 91 GeV (Z-pole), 160 GeV (W pair production threshold), 240 GeV (Higgs resonance) and 365 GeV ($t \bar{t}$ threshold).
