Selected advances in the accelerator design of the Future Circular Electron-Positron Collider (FCC-ee)
/ FCC Collaboration
In autumn 2023, the FCC Feasibility Study underwent a crucial “mid-term review”. We describe some accelerator performance risks for the proposed future circular electron-positron collider, FCC-ee, identified for, and during, the mid-term review. [...]

Electron acceleration by laser-plasma techniques is approaching maturity and is getting ready for the construction of particle accelerators with dedicated applications. We present a general methodology showing how beam physics studies can be used to achieve a specific parameter set in a laser-plasma accelerator. [...]

The International Muon Collider Collaboration (IMCC) is studying a 3 TeV center-of-mass muon collider ring, as well as a possible next stage at 10 TeV. Muons being 200 times heavier than electrons, limitations from synchrotron radiation are mostly suppressed, but the muon decay drives the accelerator chain design. [...]

FCC-ee is a proposed lepton collider with a circumference close to 100 km to produce an unprecedented amount of luminosity. The FCC-ee optics tuning working group is addressing one of the most critical aspects of the FCC-ee, that is the recovery of the optics design performance in presence of realistic imperfections.

In 2022, the FCC Feasibility Study management mandated aworking group to analyse the best configuration of the FCC-ee tunnelin the arc regions, in view of the construction of a mock-up of thearc half-cell. One of the main and most challenging goals of thestudy, named FCC-ee Arc Half-Cell Mock-up Project, was toperform a preliminary investigation on the principles of supportingthe Short-Straight Sections and dipoles of the half-cells, both forthe booster and for the collider machines.
