UVSOR‐II的BL 5 U于2004年重建，用于固体和表面的三维角分辨光电发射（3D‐ARPES）研究。光束线配备了螺旋/线偏振波荡器、1995年设计的名为SGM-TRAIN的老式单色仪和一个新的光电发射终端站。由于近年来它们的性能不足以研究材料的异常电/磁特性，我们重建了用于高分辨率研究的光束线，如下所示：（1）预聚焦镜的操作更新为由脉冲电机控制的高精度系统。(2)为了避免波荡器辐射带来的热负荷，采用了带水冷系统的入射狭缝。(3)SGM-TRAIN被重新安排到最佳条件，以适应波荡器光。(4)介绍了波荡器间隙和单色器控制系统的自由调谐程序。由于重建，我们成功地提高了吞吐量强度和能量分辨率…
BL5U at UVSOR‐II has been reconstructed in 2004’s for three‐dimensional angle‐resolved photoemission (3D‐ARPES) study on solids and surfaces. The beamline is equipped with a helically/linearly polarized undulator, an old‐type monochromator named as SGM‐TRAIN designed in 1995’s, and a new photoemission end‐station. Since their performances are insufficient to study anomalous electronic/magnetic properties on materials in recent years, we reconstructed the beamline for a high‐resolution study as follows; (1) The manipulation of the pre‐focusing mirror was updated to a high‐precision system controlled by pulse‐motors. (2) The entrance slit with water cooling system was adopted for avoiding the heat load from undulator radiation. (3) The SGM‐TRAIN was re‐arranged to the optimum condition to the undulator light. (4) The free tuning program of the undulator gap and monochromator‐control systems was introduced. Due to the reconstructions, we successfully improved the throughput intensity and energy resolution of...
