Quantum Cascade Laser-Sourced IR Spectrometer for Time Resolved Spectroscopy and Advanced Imaging at the Canadian Light Source

NSERC研究工具和仪器的资金将用于帮助获得一个先进的红外光谱仪，该光谱仪将被安置在加拿大唯一的同步加速器设施——加拿大光源（CLS）上并运行。CLS现有的中红外光束线是一个成熟的红外专业技术中心，为加拿大科学界提供了10多年的高亮度红外光源。波束线目前支持来自加拿大各地的一百多名用户的多学科研究项目，但需要对其核心基础设施进行新的投资，以保持其目前的卓越水平。该提案旨在为光束线配备量子级联激光源光谱仪，该光谱仪将利用红外光谱和成像技术推动新的科学进步。该仪器将提供方便的微秒分辨率光谱能力，并成为宽视场红外成像的来源。该仪器位于国家科学设施内，将提供给来自加拿大和世界各地的用户，他们希望使用传统化学、物理和生物实验室无法使用的独特工具研究广泛的材料和生物系统。与CLS中红外光束线的现有基础设施相比，该光谱仪具有两个关键优势；1)比同步加速器红外辐射亮4个数量级的光源；2)快速获取高质量时间分辨光谱的手段。所要求的基础设施与宽带同步加速器红外源高度互补，将有助于将光束线转向一个位置，从而为更大范围的应用提供科学解决方案。所要求的仪器允许访问一个科学工具，旨在研究高功率激光器优于同步加速器光的问题。波束线功能的多样化将促进波束线、CLS和加拿大红外用户社区的进一步基础设施投资。

NSERC Research Tools and Instruments funding will be used to help acquire an advanced infrared spectrometer that will be housed and operated at Canada’s only synchrotron facility, the Canadian Light Source (CLS). The existing mid-infrared beamline at the CLS is an established centre of infrared expertise and has provided the Canadian scientific community with a source of high brightness infrared light for more than 10 years. The beamline presently supports the multidisciplinary research programs of more than one hundred users from across Canada but requires renewed investment in its core infrastructure to maintain its current level of excellence. This proposal aims to equip the beamline with a quantum cascade laser sourced spectrometer that will drive new scientific advances using infrared spectroscopy and imaging. The instrument will provide facile, microsecond resolved spectroscopy capabilities and be a source for wide field of view infrared imaging. Housed at a national science facility, the instrument will be available to users from across Canada and the world who wish to study a broad range of materials and biological systems using unique tools that are not available in conventional chemistry, physics and biology laboratories. The spectrometer provides two critical advantages over existing infrastructure at the CLS mid-infrared beamline; 1) a source that is four orders of magnitude brighter than synchrotron infrared radiation and 2) the means to rapidly acquire high quality time resolved spectra. The requested infrastructure is highly complementary with a broad-band synchrotron infrared source and will help pivot the beamline to a position where it can offer scientific solutions for a greater range of applications. The requested instrument allows access to a scientific tool designed to study problems where high powered lasers outperform synchrotron light. Diversifying the beamline capabilities will catalyze further infrastructure investment in the beamline, the CLS, and the Canadian infrared user community.
