将单晶金刚石探测器暴露于由EC-JRC-IRMM的货车de Graaff中子发生器产生的能量范围为7 MeV至20.5 MeV的准单能中子场。记录了中子与金刚石（碳）相互作用的脉冲高度谱（PHS），以导出该探测器作为紧凑型快中子谱仪使用时对中子的实验响应函数。中子与碳相互作用时产生的传出带电粒子产生的几个峰使用反应Q值进行了识别。在PHS中识别了不同激发态下的（n，α），（n，p），（n，d）等核反应。峰的分析允许导出碳中的一些中子反应截面。本文的结果连同相关的不确定性。
A single crystal diamond detector was exposed to the quasi mono‐energetic neutron fields in the energy range from 7 MeV to 20.5 MeV produced by the Van de Graaff neutron generator of the EC‐JRC‐IRMM. Pulse Height Spectra (PHS) of the neutron interaction with the diamond (carbon) were recorded in order to derive the experimental response function of this detector to neutrons in view of its use as a compact fast neutron spectrometer. Several peaks produced by outgoing charged particles produced when neutrons interact with carbon were identified using the reaction Q‐values. The corresponding nuclear reactions, such as (n,α), (n,p), (n,d) for different excitation states were identified in the PHS. The analysis of the peaks allows the derivation of some neutron reaction cross sections in carbon. The results are presented in this paper together with the associated uncertainties.
