本研究探讨了使用GEANT4工具包对新型嵌入式球形构型设计的热中子探测效率进行估算。首先，在GEANT4工具包的几何类别类中，设计单层和多层嵌入式球形构型，采用硼（B-10）转换材料，随后估算不同半径下（范围在0.05 μm至5 μm）单层和多层嵌入式球形探测器的模拟热中子探测效率。单层嵌入式球形探测器构型在最佳（临界）半径约为4.55 μm时获得的最大热中子探测效率为5.1%。观察到随着嵌入式球形探测器构型层数的增加，热中子探测效率也随之提高。此外，还研究了低电平鉴别器（Low Level Discriminator）变化水平及不同B-10富集度对效率的影响。最后，对典型的10层嵌入式球形探测器构型在典型低半径（200 nm）和高半径（3 μm）下的histoplot进行了研究。
