用于测量快、热、慢中子的液态闪烁体LSPN的研究

Liquid scintillator LSPN used in detection of fast thermal and slow neutrons

LSPN是一类新型有机液态闪烁体。它分为含^(10)B的LSPNJ和含^(127)I的LSPNI两种。前者主要用于测量热、慢中子,而后者则用于测量快、慢中子。LSPNJ可作在线监测,而LSPNI则能避开强γ场的干扰作离线测量。它们的测量误差小于10％,而测量效率可达70％以上。

A new species of organic liquid scintillator, called LSPN, is invented by the authors. It has two kinds of subgroup, LSPNJ and LSPNI, containing 10B and 127I respectively. The former is mainly used for the detection of thermal and slow neutrons, and the latter, of fast and slow neutrons. LSPNJ can be applied in on-line monitoring while LSPNI in off-line so as to avoid the interference of a strong gamma ray field. Their mea-surement errors are lower than 10% and efficiencies higher than 70%.
