Abstract


Excitation function and angular distribution of the experimental use of the China Institute of Atomic Energy HI - 13 tandem accelerator and detector fast neutron time-of-flight spectrometer in N gas target under the conditions to carry out the 15N ( p , n) 15O reaction neutron yield measurements. Monte-Carlo method to complete the simulation experiments using liquid scintillation detector light response function is given to determine the detection efficiency of the detector system . Completed 6.029MeV-8.056MeV energy proton energy range of 38 points , 0 -degree direction of neutron yield excitation function measurement data processing applications Monte-Carlo method caused the gas target entrance window neutron fluence attenuation correction. The experimental results showed that in the incident proton energy 5.82MeV 6.29MeV 7.57MeV three energy points , 0 degree direction of neutron yield excitation function there are three formants , but the peak position and the size of the cross-section values ??are DROSG2000 evaluation and PTB data deviate . Multi-detector fast neutron time-of-flight spectrometer on three main detector to carry out the measurement of the 15N ( p, n ) 15O reaction neutron source angular distribution data , completed 15 incident proton energy interval of 6.029MeV-8.056MeV able measurement of the angular distribution of data points , given the range of 0-160 degrees 15 angle of each energy point angular distribution data were compared with DROSG-2000 evaluation data and PTB data , the results show that the experimental measurement angle the distribution data DROSG-2000 evaluation data and PTB data is broadly consistent with the trend , but there are differences in the specific section magnitude . Neutron fluence attenuation corrected data processing using the Monte-Carlo method due to the gas target entrance window .
