| 摘 要： |  长期以来，惯性约束聚变（ICF）研究软X射线诊断科学仪器设备的元器件标定工作主要依赖同步辐射光源X射线辐射计量站进行。该类装置通常与用于开展ICF研究的大型激光装置分处两地，难以满足ICF研究软X射线元器件实时实地的标定应用需求。另外，由于同步辐射和ICF激光等离子体产生的X射线辐射特性存在较大差异，同步辐射计量站的标定结果事实上也不能完全反映元器件在ICF实验应用中的计量响应特性。本文首先介绍一种基于单光学元件的软X射线紧凑型无谐波光源单色化技术，以此为基础提出研制基于ICF激光等离子体X射线源的同源、同几何位形、双束比较校准的多能量通道光源单色化系统，用于ICF应用软X射线元器件的在线标定。新系统一方面可望满足ICF软X射线元器件实时实地的标定应用需求；另一方面，其提供的标定光束的技术特征将最大可能地接近ICF激光等离子体X射线辐射本身。配备相应的X射线二极管（XRD）和标准探测器之后，该系统将形成一套具有在线自校准功能的新型多通道δ能量响应软X射线能谱仪。 |

| Abstract: | For a long time, the calibration of soft X-ray diagnostic equipment components of ICF research mainly depends on the synchrotron radiation source X-ray metrology station. This kind of device is usually located in a different place from the large laser facility for ICF research, thus it is difficult to meet the real-time field calibration application requirements of ICF’s research soft X-ray components research. In addition, in view of the great difference between the radiation characteristics of synchrotron radiation X-ray and ICF laser plasma X-ray, the calibration results of synchrotron radiation measurement station can not completely measure the response characteristics of components in ICF experiments. In this paper, a kind of monochromatic technology for compact non-harmonic soft X-ray source is introduced. Based on this technology, a monochromatic system of multi energy channel source based on ICF laser plasma X-ray source with homologous, geometric configuration and double beam comparison calibration is developed for on-line calibration of soft X-ray components in ICF applications. The new system is expected to meet the requirements of real-time calibration application of ICF’s soft X-ray components, while the technical characteristics of its calibration beam will be as close as possible to that of the ICF laser plasma X-ray radiation. |
