Description

At the SIS/ESR accelerator facility at GSI in Darmstadt the 4π-detector system FOPI is under construction at present. It is designed for the investigation of central collisions of heavy ions in the energy range up to 2 A GeV. As phase I of this detector a forward wall has been built and used in various experiments. It comprizes a total number of 764 scintillators with an additional shell of 188 thin ΔE-detectors in front of it and covers the full azimuth of the polar angles from 1deg to 30deg. The velocity and the nuclear charge of the fragments are determined by a combined time-of-flight and ΔE measurements. (orig.)
