PARAMETER SPACE FOR THE MAGNETIC DESIGN OF NESTED MAGNETS IN THE FCC-ee ARC CELL

The Future Circular Collider (FCC-ee) is designed to explore the 𝑍 0 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. For this, it is necessary to explore the possible combinations of the different magnet types in the cell, namely: dipoles, quadrupoles and sextupoles. Specifications in terms of strength and alignment tolerances are reviewed in this paper.
