摘　　要：光激中子由^(226)Ra γ源发射的γ量子轰击氘靶产生,由~3He正比管阵列组成的高灵敏中子—中子甄别探测器记录,给出计算氘靶内氘含量的信息。该装置主要用于含氘部件氘含量的无损测定。A low level photoneutron detection equipment has been developed. The photoneutrons produced .by interaction between 22eRa gamma quanta and deutron (D) target are detected with n-n discrimination detector made up of sHe proportional counter array. The D-content information in the target can be obtained from the measured photoneutron counts. This equipment developed is mainly used 'for nondestructive D-content measurement of D-devices.
