Detector for FCC-ee



This is the abstract of our nice paper that will describe the requirements and design concepts of a detector for the FCC-ee accelerator. To do match the fabulous statistical precision of the FCC-ee extremely good detector performnace is required. The detector features a 2 T solenoidal field, will have a ultralight silicon vertex detetor, a large gas drift volume, and electromagnetic and hadronic calorimeter sections. Details will be given also on the luminosity measurement.


The FCC-ee (Bicer 2014) is the potential first step. For this reason, it might be build in China.

Machine integration and physics requirements are summarized. Event and background rates are given at the different energies. The overall design philosophy (low mass, muon momentum resolution, particle flow and granularity, extreme h/e/mu separation…) is described. Two options for the magnet are described using the small coil as baseline. The small coil option is shown in Fig. \ref{fig:DetectorLayout}

Synergies with CEpC are also addressed.

This detector will be much lighter then the ATLAS (ATLAS Collaboration 2008)and CMS (CMS Collaboration 2008) detectors.


The mechanics of the chamber is described and also its readout. Possible safety aspects of long wires drift chambers are addressed. Hit resolution is discussed.
