已知硼中子俘获疗法（BNCT）是需要中子照射的有效放射癌症疗法。基于加速器的中子源产生的中子场具有各种能谱，并且有必要评估治疗场中的中子谱。然而，用于测量治疗领域的中子谱的方法还没有很好地建立，许多研究人员正在努力改进所使用的谱仪。在本研究中，我们开发了一种新的中子谱仪的原型，可以更准确和精确地测量中子谱。光谱仪基于与邦纳球光谱仪相同的理论，并且它使用液体减速剂和吸收剂。通过对所研制的光谱仪进行实验测试，最终揭示了原型探测器存在的问题和必要条件。
Boron neutron capture therapy (BNCT) is known to be an effective radiation cancer therapy that requires neutron irradiation. A neutron field generated by an accelerator-based neutron source has various energy spectra, and it is necessary to evaluate the neutron spectrum in the treatment field. However, the method used to measure the neutron spectrum in the treatment field is not well established, and many researchers are making efforts to improve the spectrometers used. In the present study, we developed a prototype of a new neutron spectrometer that can measure the neutron spectra more accurately and precisely. The spectrometer is based on the same theory as that of the Bonner sphere spectrometer, and it uses a liquid moderator and an absorber. By carrying out an experimental test of the developed spectrometer, we finally revealed the problems and necessary conditions of the prototype detector.
