  The TLEP Design Study Working Group published "First Look at the TLEP Physics
Case" in December 2013. TLEP, a 90-400 GeV high-luminosity, high precision,
e+e- machine, is now part of the Future Circular Collider (FCC) design study,
as a possible first step (named FCC-ee) towards a high-energy proton-proton
collider (named FCC- hh). The above paper presents an initial assessment of
some of the relevant features of the FCC-ee potential, to serve as a starting
point for the more extensive design study that is now carried out. FCC-ee will
provide the opportunity to make the most sensitive tests of the Standard Model
of electroweak interactions. The first requirement of the detector must
therefore be to ensure it has the capability to make these precise tests. The
detector must have excellent vertexing and tracking performances and a highly
granular, homogeneous calorimetric system covering as great a solid angle as
possible. Following the ALEPH philosophy of using as few detection techniques
as possible, we propose to evaluate the modifications that would be needed for
an "ALEPH-like" detector to fulfil the requirements of FCC-ee. We will
investigate the use of Micromegas detectors instead of limited-streamer tubes
and will adjust the size of the detector and its granularity.
