| 摘 要： | 国内基于串列加速器建立了144keV~15MeV的单能中子参考辐射场，解决了20MeV以下能区中子探测器注量、剂量等参数的量值溯源，但尚未建立20MeV以上能区准单能中子参考辐射场。随着航天空间中子探测任务的需要以及地面高能质子加速器的发展，20MeV以上能区准单能中子参考辐射场需求越来越突出。发展20MeV以上能区高能中子参考辐射场对于满足国防需求、推动中子计量学科发展具有重要意义。

| Abstract: | 144keV~15MeV mono-energetic reference fields based on tandem accelerator have been established in China.The calibration of neutron detector and traceability of neutron fluence and dosimetry have been realized below 20MeV.But there are no quasi mono-energetic reference fields above 20MeV in China.With the developments of neutron detector for space radiation and the developments of high energy proton accelerators,the needs for neutron reference fields above 20MeV are more and more intense.Being established of quasi mono-energetic neutron reference fields above 20MeV is very important for resolving defense industry needs and pushing development of neutron metrology. |
