摘要
大型惯性约束聚变(ICF)装置靶场将从主放大系统输出的平行激光阵列转换为靶室附近的球形阵列,并以特定的角度进入终端光学系统。靶场传输光路排布作为靶场光传输系统总体结构设计的依据,在满足物理和光学等要求的基础上,还应重点考虑工程建设成本和系统维护性能。随着ICF装置规模的增大,打靶激光光束数量增加,靶场传输光路排布难度增加。结合目前国内外大型ICF装置,分析了靶场传输光路排布的特点,讨论了传输光路排布与光传输系统布局、光机结构设计和系统维护性能的关系,为我国更多束激光打靶的ICF装置的靶场传输光路排布提出建议。
Abstract
In the target area of large inertial confinement fusion (ICF) facility, the rectangular beams arrangement at the main amplifier output is mapped to the spherical-geometry beams configuration near the target chamber. The beams are imported into the final optical assemblies with special angles. The beam transport system is designed based on the beams arrangement. The beams arrangement should meet physical and optical requirements. At the same time, the construction cost and the maintenance performance of the beam transport system should be seriously considered. In larger ICF facility, the beams arrangement is much more complex with the increase of beam number. The beams arrangements of the large facilities in the world are analyzed. The relationships between the beams arrangement and the layout of beam transport system, the opto-mechanical design and the maintenance performance are discussed. Some advices of the beams arrangement are given for the ICF facility with much more multiple beams.
