Experiment study on neutron flux density space-time characteristic in ADS "Venus 1#"

The subcritical neutronics characteristic of ADS subcritical assembly "Venus 1#" is analysed in this paper;the necessity to study the prompt neutron flux density space-time characteristic of "Venus 1#" by experiment method is elucidated;the method(pulsed source method) and experiment plan are presented;the data procession is finished and some meaningful results are obtained,which establishes a base for next stage study.
