在NTT同步辐射装置的正导加速环（NAR）上建立了实时光电子能谱的VUV束线（ABL-3B）。为了接收水平发散角为20 mrad的同步辐射入射光束，设计了一个长1.38 m的圆柱弯曲前镜。该镜子由四个平面镜块连接在一起，安装在具有c形截面的钢架梁上。该镜架可通过新型弯曲装置进行弯曲，弯曲动量为1388 kg cm，达到最佳曲率半径63.9 m。通过弯曲前镜，在样品位置上初步得到3.5 mm (H)×1.8 mm (V)的聚焦光斑。当存储电子束电流为50 mA，将“蚱蜢”单色仪调至130 eV时，光子通量为1.5×1010photons/s，能量分辨率为0.5 eV。
A VUV beamline (ABL-3B) for real-time photoelectron spectroscopy has been developed at the normal-conducting accelerating ring (NAR) of the NTT synchrotron radiation facility. To accept the incident synchrotron radiation beam with the wide horizontal divergence angle of 20 mrad, a 1.38-m-long cylindrically bent front mirror was devised. This mirror was composed of four plane mirror blocks connected together and mounted on a steel holder beam having a C-shaped cross section. The mirror holder can be bent by a novel bending device with a momentum of 1388 kg cm to achieve the optimum radius of the curvature of 63.9 m. The focused spot of 3.5 mm (H)×1.8 mm (V) was preliminarily obtained on the sample position by bending the front mirror. When the stored electron beam current was 50 mA and the “grasshopper” monochromator was tuned at 130 eV, a photon flux of 1.5×1010photons/s was obtained with the energy resolution of 0.5 eV.
