With a circumference of approximately 91 km, the Future Circular electron-positron Collider, FCC-ee, aims for unprecedented luminosities at beam energies from 45.6 to 182.5 GeV. A major challenge is reaching its design performance in the presence of magnet misalignments and field errors. [...]

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. [...]

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.

Accelerator physics relies on numerical algorithms to solve optimization problems in online accelerator control and tasks such as experimental design and model calibration in simulations. The effectiveness of optimization algorithms in discovering ideal solutions for complex challenges with limited resources often determines the problem complexity these methods can address. [...]

Muon Accumulator Ring Requirements for a Low Emittance Muon Collider from Positrons on Target
/ Boscolo, Manuela (Frascati) ; Antonelli, Mario (Frascati) ; Blanco-García, Oscar (Frascati) ; Collamati, Francesco (INFN, Rome) ; Guiducci, Susanna (Frascati) ; Keller, Lewis (SLAC) ; Liuzzo, Simone (ESRF, Grenoble) ; Raimondi, Pantaleo (ESRF, Grenoble) ; Schulte, Daniel (CERN)
Very low emittance muon beams can be produced by direct annihilation of about 45~GeV positrons on atomic electrons in a thin target. With such a muon beam source, a mu+mu- collider can be designed in the multi-TeV range at very high luminosities. [...]

A new scheme to produce muon beams characterised by very low emittance, in such a way to avoid the need for cooling, using a positron beam of about 45 GeV interacting on electrons on target is being studied by our group. This scheme is challenging and innovative, and needs a full design study to be developed. [...]

Study of double triple bend achromat (DTBA) lattice for a 3GeV light source

Starting from the concepts of the Hybrid Multi Bend Achromat (HMBA) lattice developed at ESRF and of the Double-Double Bend Achromat(DDBA) lattice developed at Diamond, we present a new cell tha tincludes all the advantages of the two designs. The resulting Double Triple Bend Achromat(DTBA) cel lallows for a natural horizontal emittance of less than 100pm with a large dynamic aperture and lifetime. [...]
