| Abstract: | The experiment principle of reflected neutron measurement for D-D neutron source in cement reflector was introduced.The fission rate of 235U(wrapped with cadmium) and 238U were measured in three conditions: without reflector、with reflector and just background.The reflection coefficient of the experiment assembly was abtained and analyzed subsequently. |
