This report summarises the study of a general purpose detector for the FCC-hh, a 100 TeV hadron collider with peak luminosity of 3 ⋅ 1035 cm-2s-1. A pileup of 1000 pp collisions per bunch-crossing, highly boosted objects as well as radiation levels up to 1018 hadrons/cm2 are just three of the challenges that such a collider poses. The general specifications for such a detector in terms of resolution, granularity, acceptance and radiation tolerance are discussed. A specific detector layout is proposed and its performance is simulated, discussed and parameterized. This parameterization is then used to evaluate the performance for key benchmark physics topics, such as the precision measurement of the Higgs boson couplings and the discovery reach for several frameworks beyond the Standard Model.
