【Abstract】 The array BF₃ detector was designed and developed for measuring DT pulse neutron yields. The detection sensitivity of detector was calibrated by a series of neutron measurement on the accelerator. The relative measuring data and its uncertainty from array BF₃ detection were obtained and compared with that from other measuring （methods）. Experiment data verifies the reliability of array BF₃ detector to be used for （measuring） DT pulse neutron.更多还原
