国家同步辐射实验室拥有中国的第一个专用同步辐射设施--合肥光源。HLS于2016年全面升级为HLS II。在机器升级后，红外光束线进行了改造，以匹配新的存储环，并提高了其性能。红外辐射是从接收角度为65(H)×55(V)mrad(2)的弯曲磁体(1度端口)提取的，包括边缘辐射和恒定电场辐射。重建了两个终点站。一个用于远红外到近红外的光谱学实验，另一个用于中红外显微光谱学和成像实验。在本文中，我们详细介绍了新的红外光束线和终端站，包括光学和在两个终端站上开发的实验技术。
National Synchrotron Radiation Laboratory (NSRL) owns the first dedicated synchrotron radiation facility in China, Hefei Light Source (HLS). The HLS was fully upgraded to HLS II in 2016. Following the machine upgrade, the infrared beamline was reconstructed to match the new storage ring and improved its performance. The infrared radiation is extracted from a bending magnet (1 degree port) with an acceptance angle of 65(H) x 55(V) mrad(2), which including edge radiation and constant field radiaton. Two endstations were reconstructed. One is for spectroscopy experiment covering from far to near infrared, the other one is for mid-infrared microspectroscopy and imaging experiment. In this paper, we introduce the new infrared beamline and endstations in detail, including optics, experimental techniques developed at two endstations.
