Abstract

Phantom experiments to evaluate thermal neutron flux distribution were performed using the Scintillator with Optical Fiber (SOF) detector, which was developed as a thermal neutron monitor during boron neutron capture therapy (BNCT) irradiation. Compared with the gold wire activation method and Monte Carlo N-particle (MCNP) calculations, it was confirmed that the SOF detector is capable of measuring thermal neutron flux as low as 10(5) n/cm(2)/s with sufficient accuracy. The SOF detector will be useful for phantom experiments with BNCT neutron fields from low-current accelerator-based neutron sources.

摘要

使用带有光纤的闪烁体（SOF）探测器进行了评估热中子通量分布的模体实验，该探测器是作为硼中子俘获疗法（BNCT）照射期间的热中子监测器而开发的。与金线活化法和蒙特卡罗N粒子（MCNP）计算相比，证实了SOF探测器能够以足够的精度测量低至10(5) n/cm(2)/s的热中子通量。SOF探测器将有助于使用基于低电流加速器的中子源进行BNCT中子场的模体实验。
