  CERN has recently launched the Future Circular Collider (FCC) study to deal
with all aspects of an ambitious post-LHC possible programme. The emphasis of
the study is on a 100 TeV proton collider to be housed in a 80-100 km new ring
in the Geneva region. An electron machine will also be considered as a possible
intermediate first step (FCC-ee). The study benefits from earlier work done in
the context of TLEP and has already published a parameter table, to serve as
the basis for the work to be done. The study aims to publish a conceptual
design report at around 2018. The recent discovery of a light Higgs boson has
opened up considerable interest in circular e+e- Higgs factories around the
world. FCC-ee is capable of very high luminosities in a wide centre-of-mass
(ECM) spectrum from 90 to 350 GeV. This allows the very precise study of the Z,
W and H bosons as well as the top quark, allowing for meaningful precision
tests of the closure of the Standard Model.
