As part of the advancements in the characterization of the irradiation field for boron neutron capture therapy, we are developing a Bonner-sphere neutron energy spectrometer for which the liquid moderator is changed remotely. Simulations were performed to find the best combination of liquid moderators and composition of the Bonner spheres. The combination finally adopted was five-layered concentric acrylic spheres with two different liquid moderators and six optimal patterns for moderator injection.

用于硼中子俘获治疗辐照场表征的 Bonner 球谱仪中远程可变慢化剂的研究。

作为硼中子俘获疗法辐照场表征进展的一部分，我们正在开发一种 Bonner-sphere 中子能谱仪，可远程更换液体慢化剂。进行模拟以找到液体慢化剂和邦纳球组成的最佳组合。最终采用的组合是具有两种不同液体慢化剂和六种慢化剂注入最佳模式的五层同心丙烯酸球。
