The third scintillator monitors the O255200100020 random coincidence rate. O255200100021 (HPGE) The detector for the off-line measurements has aO255200100022 multi-layer shielding with an active muon-veto to O255200100023 reduce the background. O255200100024 SAMPLE The graphite target has a lateral size of O255200100025 (8.00+-0.05)x(8.00+-0.05)cm2 and a thickness of O255200100026 (7.1+-0.1)mm in beam direction. The density is O255200100027 (1.8+-0.1)g/cm3.
