Description
Monochromatization is one of the most intriguing proposed operation modes of the FCC-ee, enabling a significant reduction of the centre-of-mass (CM) energy spread to a level comparable to the Higgs boson’s natural width. Previous studies demonstrated its feasibility using earlier versions of the FCC-ee optics. Building on that foundation, this work presents the updated implementation based on the Global Hybrid Correction (GHC) v23 lattice. The beam-beam effects on the optics with high dispersion values have been explored using the strong-strong simulations on the simplified lattice. In parallel, a first draft implementation of the scheme on the Local Chromaticity Correction (LCC) lattice is explored. The performances of the two optics types are compared in terms of luminosity and energy spread, supported by detailed simulation results. This comparison provides an early outlook on the potential operational flexibility of future FCC-ee configurations operating in monochromatization mode.
