The Tehran Research Reactor is the only appropriate and available neutron source in Iran for clinical boron neutron capture therapy (BNCT). One of the requirements for BNCT is to carefully evaluate and measure the therapeutic neutron beam (epithermal neutrons) as well as the fast and thermal neutron components for successful treatment. In this research, a multi-moderator neutron spectrometer (MMNS) with LiI(Eu) scintillator as neutron counter was proposed for these measurements in the range of 10−11 eV to 15 MeV. The results confirmed promising precision of the designed MMNS for the epithermal spectrum; however, the angular dependency of the therapeutic beam due to any probable change in the beam-shaping assembly should be considered.

用于德黑兰研究堆的 BNCT 研究的多慢化剂中子能谱仪

德黑兰研究堆是伊朗唯一适用于临床硼中子俘获疗法 (BNCT) 的可用中子源。BNCT 的要求之一是仔细评估和测量治疗性中子束(超热中子)以及快中子和热中子成分,以实现成功治疗。在这项研究中,提出了一种以 LiI(Eu) 闪烁体作为中子计数器的多慢化中子能谱仪 (MMNS),用于在 10 -11  eV 至 15 MeV范围内进行这些测量。结果证实了为超热光谱设计的 MMNS 的有希望的精度;然而,应考虑由于光束整形组件的任何可能变化而导致的治疗光束的角度依赖性。
