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 the beamline to be able to investigate three-dimensional electronic-structures using 3D-ARPES.
