The Neutron Wall(NW)is one of the key detectors for the external target experiment of CSRm. There are 36 scintillator units and 216 sampling calorimeter units which are arranged in 14 layers.The de- tector modules are parallel arranged in each layer and perpendicular to the neighboring layers.The size of scintillator bar is 1 440(length)XS0(width)X80(thickness)mm~3 and that of the calorimeter unit is 1 500 (length)×80(width)×70(thickness)mm~3.
