作为上海同步辐射装置(SSRF)光电子实验系统(Dreamline)的一个分支，设计了一种新的角度分辨光电子能谱(ARPES)光束线。其目的是为来自世界各地的用户提供进行ARPES实验的强大工具。在光束线的设计和建造过程中，由于其高能量分辨率、高光子通量和高聚焦质量，需要解决许多技术难题，包括单色器的设计、Kirkpatrick-Baez(KB)反射镜系统的设计和光学元件的制造。本文介绍了知识库镜像系统的工作原理和设计方案。讨论了位移函数的实际意义。对于垂直直线驱动机构，分析了其轴向变形和径向变形对分辨率和重复性的影响。结果表明，该方法在误差允许范围内。线性分辨率和重复性、角度分辨率和重复性分别为0.56xμm、1.6xμm、0.6“和1.08”，保证了KB反射镜的高精度运动，进一步提高了光束线的性能。光束线的模拟和光线跟踪结果表明，该光束线在1000EV能量分辨率优于11.2兆电子伏特，光子通量大于1011phs/S/0.01%BW，样品上的光斑尺寸约为15μm×47.7mμm(半高宽)，性能超出预期。
A new angle resolved photoelectron energy spectrum (ARPES) beamline is designed as a branch of the photoelectron experimental system (dreamline) at Shanghai Synchrotron Radiation Facility (SSRF). Its purpose is to provide a powerful instrument to conduct ARPES experiments for users from all over the world. During the design and construction of the beamline, many technical difficulties needed to be solved because of its high energy resolution, high photon flux and high focusing quality, including the design of monochromator, the design of Kirkpatrick–Baez (KB) mirror system and the manufacture of the optics. In this paper, the KB mirror system is described, including its principle and design scheme. The practical significance of displacement function is discussed. For vertical linear driving mechanism, the variation of resolution and repeatability induced by its axial deformation and radial deformation is analyzed. The results show that it is within the scope of permissible error. Linear resolution and repeatability, and angle resolution and repeatability are tested as 0.56 μm, 1.6 μm, 0.6″ and 1.08″, which guarantee the high accurate motion of KB mirrors and further improve the performance of the beamline. The simulation and ray tracing results of the beamline show that the energy resolution is better than 11.2 meV at 1000 eV, the photon flux is higher than 1011phs/s/0.01%BW and the spot size on sample is about 15 μm × 4.7 μm (FWHM), demonstrating that the performance is beyond prediction.
