我们报告了在MAX-LAB同步辐射实验室的MAX-II存储环上新的I1011光束线的特性，并给出了第一个结果的例子。这条光束线使用椭圆偏振波动光源，产生偏振态可变的软X射线。它在0.2keV到1.7keV的能量范围内提供高通量和高亮度的圆偏振X射线，覆盖了晚期3D元素的L边缘。新的光束线将使用一个八极磁铁终端站运行。它是专门为解决通常与磁场和同步辐射终端站相关的有限光学接入问题而设计的。八个水冷磁铁允许在任何方向上施加高达1T的磁场。在外加磁场下，X射线吸收光谱、X射线共振反射率和相应的磁变量，即XMCD、XMLD和XRMS实验也是可能的。高通量允许使用稀磁系统，如超薄膜和纳米结构。
We report on the characterization of the new I1011 beamline at the MAX-II storage ring, in the MAX-lab synchrotron radiation laboratory and give examples of first results. This beamline is using an Elliptically Polarizing Undulator source, producing soft x-rays of a variable polarization state. It delivers high flux and high brightness circularly polarized x-rays in the energy range 0.2 to 1.7 keV, covering the L-edges of the late 3d elements. The new beamline will operate with an octupole magnet endstation. It is specially engineered to solve the problem of the limited optical access typically associated with magnetic fields and synchrotron radiation endstations. Eight water-cooled magnets allow the application of the magnetic field of up to 1 T in any direction. X-ray absorption spectroscopy, X-ray resonant reflectivity and the corresponding magnetic variants, i.e., XMCD, XMLD and XRMS experiments are possible also under an applied magnetic field. The high flux allows working with dilute magnetic systems such as ultra-thin films and nano structures.
