DESCRIPTION:Speakers: Duccio Abbaneo (CERN)\n\nA new detector concept has 
 been developed\, with the goal of evolving it into a full detector proposa
 l for FCC-ee. The design emphasizes performance\, simplicity\, and cost-ef
 fectiveness\, combining innovative technologies with a coherent and robust
  overall architecture.\nAt its core is a full-MAPS tracker\, providing exc
 ellent spatial resolution with an extremely low material budget\, and ther
 efore outstanding tracking and vertexing performance. It is complemented b
 y an ARC detector (Array of RICH Cells)\, enabling particle identification
  over a broad momentum range.\nThe electromagnetic calorimeter is based on
  the novel GRAiNITA technology\, combining excellent energy and position r
 esolution with a significantly reduced cost compared to monolithic crystal
  calorimeters. In addition\, a compact silicon–tungsten sampling calorim
 eter\, also based on MAPS\, enables luminosity measurement through the rec
 onstruction of Bhabha events.\nThese subdetectors are housed inside a supe
 rconducting solenoid providing a 3 T magnetic field. Outside the coil\, a 
 large dual-readout hadronic calorimeter with an iron absorber ensures adeq
 uate hadronic energy resolution while also serving as the magnetic flux re
 turn\, resulting in an efficient and compact overall design. A simple muon
  tagging system completes the detector.\nThe design effort has so far focu
 sed on the tracker\, reaching a level of detail sufficient for a reliable 
 estimate of the material budget - the key driver of tracking performance. 
 The results demonstrate that an optimized all-MAPS tracker is a valid opti
 on for FCC-ee physics\, combining excellent performance\, robustness\, and
  scalability.\nThe presentation will introduce the overall detector concep
 t and discuss the tracker design and performance in more detail.\n \n \n
