Abstract

The study revolves around a novel 3-D trapezium design, employing orthocarborane in the converter section of a semiconductor neutron detector to detect thermal neutrons. This configuration enhances neutron detection efficiency and provides insights into key design parameters. Using Geant4 simulations, the critical converter width and area for optimal efficiency has been determined. The converter utilizes the ¹⁰B (n, α)⁷Li reaction, achieving a peak efficiency of 13.3 % at 8.5 μm width and 72.25 μm² area with 100 % ¹⁰B enrichment. The effect of ¹⁰B enrichment (20 %–100 %) and low-level discriminator thresholds (100–800 keV) on efficiency has also been analyzed. Histoplot study has been conducted to understand the converter width's influence on the energy spectra of emitted charged particles.

优化中子探测：梯形o -碳硼烷转炉

这项研究围绕着一种新颖的三维梯形设计，在半导体中子探测器的转换部分使用正硼烷来探测热中子。这种配置提高了中子探测效率，并提供了对关键设计参数的深入了解。利用Geant4仿真，确定了最优效率的临界变换器宽度和面积。该转化器利用10B (n, α)7Li反应，在8.5 μm宽度和72.25 μm2面积处，10B富集100%，效率达到13.3%。还分析了10B富集（20% - 100%）和低水平鉴别器阈值（100-800 keV）对效率的影响。通过直方图研究，了解了转换器宽度对发射带电粒子能谱的影响。
