High Acceptance Spectrometer
The specrometer is divided into 6 sectors surrounding the beam axis covering large angular acceptance between 16 and 88 degrees. HADES is comprised of the following components: A diamond START detector, a Ring Imaging Cherenkov (RICH), four sets of Multiwire Drift Chambers (MDC), a superconducting toroidal magnet and a multiplicity/electron trigger array consisting of granular pre-shower detectors at forward angles and two time of flight walls: a scintillator based time-of-flight wall (TOF) and the RPC wall built from resisitive plate chambers.
