我们在广岛大学广岛同步辐射中心的HSRC研制了一台自旋分辨光电子谱仪。用Ni（1 1 0）的二次电子作为自旋极化电子源对极化计进行了性能测试，得到有效谢尔曼函数的最佳优值为1.8 × 10 ~（-4），散射强度分别为-0.16和7.1 × 10 ~（-4）。我们的结果表明，自校准的这种类型的偏振计与散射电子的大收集角是可能的。(c)2005 Elsevier B. V.保留所有权利。
We have developed a spin-resolved photoelectron spectrometer with a compact retarding-type Mott spin polarimeter at HSRC, Hiroshima Synchrotron Radiation Center, Hiroshima University. Secondary electrons from Ni(1 1 0) were used as the spin-polarized electron source to do performance test of the polarimeter and the best figure of merit was found as 1.8 x 10(-4) for the effective Sherman function and the scattering intensity as -0.16 and 7.1 x 10(-4), respectively. Our results show that the self-calibration is possible for this type polarimeter with a large collection angle for scattered electrons. (c) 2005 Elsevier B.V. All rights reserved.
