First comments on a descoped/staged FCC-ee / Blondel, Alain (LPNHE, Paris) ; Grojean, Christophe (DESY ; Humboldt U., Berlin) ; Janot, Patrick (CERN) ; Wilkinson, Guy (Oxford U.)
In response to its remit, the European Strategy Group (ESG) recommended the electron-positron Future Circular Collider (FCC-ee) as the preferred option for the next flagship collider at CERN; and a descoped FCC-ee as the preferred alternative option (with reduced synchrotron radiation (SR) power, without a run at the $\rm t \bar t$ threshold, and with only two interaction regions) in the event that the preferred option turns out not to be feasible.
