We propose to install a state-of-the-art tender X-ray emission spectrometer (XES) in the energy region of 2-2.5 keV with additional capabilities at energies up to 7 keV at the Soft X-ray Micro-characterization Beamline of the Canadian Light Source. This is a Rowland circle based custom design driven by research activities of the Soochow-Western Centre for Synchrotron Radiation Research at Western as well as demand for high energy resolution tender X-ray emission spectroscopy by CLS users. The spectrometer provides an energy resolution of 1 eV for the detection of K alpha, beta X-rays from P and S and is equipped with a glove box. The design has gone through several iterations between the SXRMB team and the "easyXAFS" company, and is optimized for beam line optics, sampling environment and hutch space. The glove box enclosure for atmosphere control is an innovation for tender X-ray XES.

我们建议安装一个国家的最先进的招标X射线发射光谱仪（XES）在2-2.5千电子伏的能量区域，在加拿大光源的软X射线微表征光束线的能量高达7千电子伏的额外能力。这是一个基于罗兰圆的定制设计，由Soochow-Western同步辐射研究中心的研究活动以及CLS用户对高能量分辨率招标X射线发射光谱的需求驱动。光谱仪提供了1 eV的能量分辨率，用于检测P和S的K α，β X射线，并配备了手套箱。该设计在SXRMB团队和“easyXAFS”公司之间经历了多次迭代，并针对光束线光学、采样环境和箱空间进行了优化。 用于气氛控制的手套箱外壳是软X射线XES的创新。
