The Experimental Research of Nuclear Stochastic Signal Measurement System Based on ~(252)Cf Neutron Source
The experiment, based on the nuclear stochastic signal measurement system using~( 252)Cf neutron source, was performed to analyze the stochastic signals in a non-nuclear material condition. Several datasets were collected by three high-speed synchronized channels under difference scenarios (different angles and distances). According to the special relationship with ~(253)Cf source, the R_(p5d) (Ratio of Power Spectral Density) was calculated and analyzed using correlation and periodogram method with different block size. Experiment shows that the R_(p5d) remains at approximate constant amplitude in the low frequency range, and is only related to the angle between the detectors and the source. The results coincide with the theoretical analysis and verify the accuracy and effectiveness of system.
