Abstract
Abstract
One of the major upcoming challenges in particle physics is
achieving precise measurements of the Z, W, and H bosons, as well as
the top quark. To meet these targets, the next e+e- collider complex, FCC-ee, will need to achieve unprecedented
luminosities. The FCC-IS European Study is investigating the
feasibility of these challenges, with a cornerstone of the study
being the design and optimization of the high-energy booster
(HEB). This paper provides an update on the status of the HEB of
FCC-ee in light of recent developments in the injector and collider
survey, as well as an overview of ongoing work on longitudinal
stability and design robustness in relation to field, alignment, and
diagnostics errors. Constraints and effects related to the design
frequency of the accelerating cavities, as well as collective
effects, are also highlighted. Lastly, the paper presents an
investigation into an alternative arcs cell design.
