• The in-situ nondestructive testing (NDT) instrument using neutron backscattering for boron-based materials was developed successfully in this work. The capability verification of confirming qualitatively the integrity of the boron-based material as neutron absorber and characterizing quantitatively the gap defect size was demonstrated herein. For extending the technique at the fast traverse mode, a derived relationship between the defect size and output signal considering the effects of scanning speed and time constant was presented in this work for data interpretation. We also performed an experimental sensitivity analysis as a function of operation parameters. Through a comparison of the increase in output counting rate current between calculation and measurement, the deviation of the theoretical prediction at the fast traverse mode was within ±30%.
