Review study on variables for performance improvement of BF3 combination detector

In this study, variables affecting performance of BF3 neutron combination detector was suggested. Various variables including shield control to neutron backscattering, tube pressure, temperature, detector assembly are analyzed. From further study on neutron detector, neutron detection performance limitation by variables such as shield control to neutron backscattering, BF3 tube pressure, temperature, cross section, detector assembly would get more clearly and systematically solved. In this study, the fact that kind of shield could influence process of moderation or reflection of neutron or flux control or scattering and absorption block was checked. Also, the fact that pressure of tubes and number of tubes are directly connected to efficiency of detector could be checked. Temperature change of detector could change energy peak and pulse height distribution. Detector assembly, geometric arrangement and resolution of detector and dead time settings are another variables to change efficiency of detector and influence performance of detector. Utilizing these information, experiment design for detector performance improvement and investigation about efficiency improvement of combination detector would be accomplished. Ultimately, composition and development for enhanced accuracy of neutron detector are our next goal.
