Review of MAD-X for FCC-ee studies
/ Simon, Guillaume (CERN ; IJCLab, Orsay) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; De Maria, Riccardo (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne)
The design of the electron-positron Future Circular Collider (FCC-ee) challenges the requirements on optics codes (like MAD-X) in terms of accuracy, consistency, and performance. Traditionally, MAD-X uses a transport formalism by expanding the transfer map about the origin up to second order to compute optics functions and synchrotron radiation integrals in the TWISS and EMIT modules.

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.

Modelling FCC-ee Using MADX
/ van Riesen-Haupt, Léon (CERN) ; Burkhardt, Helmut (CERN) ; Persson, Tobias (CERN) ; Tomás García, Rogelio (CERN)
We present the latest developments for simulating FCC-ee using CERN’s MADX software. Along with updated benchmark studies, we describe how the latest MADX updates can facilitate the simulation of FCC-ee design features, including improvements in tapering and different options for implementing a tilted solenoid..

Parameter space for the magnetic design of Nested Magnets in the FCC-ee arc cell
/ Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne, LPAP) ; Thabuis, Adrien (CERN) ; Auchmann, Bernhard (PSI, SLS) ; Kosse, Jaap (PSI, SLS) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne, LPAP) ; Koratzinos, Michael (CERN) ; Seidel, Mike (Ecole Polytechnique, Lausanne, LPAP) ; Tomas, Rogelio (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne, LPAP)
The Future Circular Collider (FCC-ee) is designed to explore the Z and W± bosons, along with the Higgs boson and top quark, achieving exceptionally high luminosity. In order to minimize the energy lost per turn due to Synchrotron Radiation (SR) we explore the use of Nested Magnets (NMs) into the arcs cell. [...]

Simulated performance of FCC-ee IP tuning knobs
/ Jagabathuni, Satya Sai (CERN ; U. Geneva (main)) ; Zimmermann, Frank (CERN) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; Hofer, Michael (CERN) ; Carlier, Felix (Ecole Polytechnique, Lausanne)
The Future Circular electron-positron Collider (FCC-ee) is a proposed accelerator with 91 kilometres circumference that should serve as a Higgs and electroweak factory, with unprecedented luminosity. Unavoidable misalignments and field errors will generate optics errors at the interaction point (IP), whose effect will be amplified by the beam-beam collisions, which will make it challenging for the collider to reach its intended luminosity goals.

The Future Circular Electron-Positron Collider (FCC-ee) represents a cutting-edge particle physics facility designed to further investigate the Z, W± and Higgs boson in addition to the top quark. The implementation of Nested Magnets (NMs) in the FCC-ee arc cells would maintain high luminosity and reduce its energy consumption. [...]
