Measurement of Detector Neutron Energy Response Using Time-of-Flight Techniques.

摘要

The feasibility of using time-of-flight techniques at the EG and G/AEC linear accelerator for measuring the neutron response of relatively sensitive detectors over the energy range 0.5to 14MeV has been demonstrated. The measurement technique is described in detail as are the results of neutron spectrum measurements from beryllium and uranium photoneutron targets. The sensitivity of a fluor photomultiplier LASL detector with a 2-by 1-inch NE-111scintillator was determined with the two targets,and agreement in the region of overlap was very good.
