摘要：

A calorimeter for absolute neutron flux measurement has been built and tested. The calorimeter measures the heat produced when neutrons are captured via the Li-6(n, H-3)He-4 reaction. The sensitivity achieved was 1.3 X 10(6) n/s for a 1 h measurement. Comparisons with a U-235 fission chamber are in agreement. An improved calorimeter is proposed which is designed to be sensitive to 10(5) n/s for a 1 h measurement.
