A spectroscopic endstation with magnetic field, voltage, and low temperature control has been installed and commissioned at the soft X-ray beamline 08U1A of Shanghai Synchrotron Radiation Facility, which can obtain a magnetic field up to ±0.53 T, applied current and bias voltage, and cryogenic temperatures down to 14 K with a Gifford-McMahon cycle cryocooler. The endstation can perform soft X-ray absorption spectroscopy methods including total electron yield, fluorescence yield, and X-ray excited optical luminance. Combined with an elliptically polarized undulator and the in situ conditions, the endstation can effectively perform X-ray magnetic circular and linear dichroism experiments in the soft X-ray range between photon energies of 250 and 2000 eV.
一个具备磁场、电压和低温控制功能的光谱终端站已在上海同步辐射装置的软X射线光束线08U1A上安装并调试完成。该终端站可通过吉福德-麦克马洪循环低温制冷机获得高达±0.53 T的磁场、施加电流和偏置电压，并将温度降至14 K。该终端站能够执行软X射线吸收光谱方法，包括总电子产额、荧光产额和X射线激发光致发光。结合椭圆偏振波荡器和原位条件，该终端站能够在250至2000 eV光子能量的软X射线范围内有效地进行X射线磁圆二色性和线性二色性实验。
