| 摘 要： | 北京同步辐射实验室3B1B光束线为VUV真空紫外光束线,由于原束线存在接收度过小(光强弱)、光学元件易污染(真空差)、实验条件较差等问题,因此该束线一直未能很好满足实验站的要求。2001年起开始对原束线进行改建设计,改进束线能量范围为120-350 nm。束线在2003年3月完成调试并投入使用。本文介绍了改建束线的光学设计以及建成后的束线性能测试结果。

| Abstract: | Beamline 3B1B, a VUV beamline in Beijing Synchrotron Radiation Laboratory, was designed for the studies on VUV fluorescence spectroscopy and VUV circular dichroism spectroscopy of biological macromolecules. Due to the very small acceptance and bad vacuum, the beamline didn't fulfill the experiments well in past years. A new VUV beamline was designed since 2001, the photon wavelength range is from 120nm to 350nm. The beamline's construction was finished and it was put into use in March 2003. The test result shows its photon flux and resolution are greatly improved. In the paper, design and performance of the beamline is introduced. |
