As part of the external target facility(ETF)of CSR,the neutron wall is a high-efficiency detector array for measuring the neutrons with energies from several tens of MeV to ～1 GeV. It is centered in the beam axis and 14 m downstream from the target. The detector has 252 units in 14 layers,and the units are parallel to each other in the same layer and perpendicular to the adjacent layers. For each unit,two photomultiplier tubes(PMTs)R7724
