MRI: Development of a frequency-comb nearfield infrared spectrometer

eccs - 0723055吗。该计划的目标是通过开发散射扫描近场红外显微镜（S-SNIM）来推进用于纳米级实验的红外近场光谱显微镜。由于物质的许多基本性质都具有落在近红外和中红外“指纹”能量范围内的特征能量尺度，红外光谱显微镜是最广泛的分析技术之一，通常应用于国家安全、法医学、大多数自然科学、艺术史、材料科学和工程等不同领域。因此，一种能够在纳米尺度上进行精确的中红外光谱和微观测量的仪器将为分子物质的检测提供几乎通用的手段，并为固体中的基本激发提供独特的见解。所提出的S-SNIM将在低温下实现近/中红外区域的光谱和成像，空间分辨率低至10纳米。更广泛的影响：提议的仪器将显著影响地方、区域和国家层面的研究基础设施。在当地，超过25名研究生和研究人员隶属于加州大学圣地亚哥分校的9个研究小组，将加强他们的培训和研究。在区域内，一些工业合作伙伴将获得使用微光谱学仪器的机会。在全国范围内，拟议的仪器将减轻国家实验室超额订购的同步加速器光束线的负担，而与安捷伦和工业合作伙伴合作的这些仪器的商业化将有助于保持美国在制造纳米级探测物质的最先进仪器方面的领先地位。教育活动包括开设新的专题课程、提供跨学科教育的机会和培训代表性不足的群体。后者涉及到加州大学圣地亚哥分校普鲁斯学院的初高中学生，研究生和博士后学者的招募和指导，以及与CAMP（加州少数民族参与联盟）一起的本科生。

ECCS-0723055S. Mookherjea, University of California, San Diego Intellectual meritThe goal of the proposed program is to advance IR near-field spectro-microscopy for experiments at the nanoscale through the development of a Scattering Scanning Nearfield Infrared Microscope (S-SNIM). Since many fundamental properties of matter have characteristic energy scales falling in the near and mid-infrared "fingerprint" energy range, infrared spectro-microscopy is one of the most widespread analytical techniques and is routinely employed in such diverse areas as national security, forensics, most of the natural sciences, art history, materials science and engineering. Therefore, an instrument that permits accurate mid-IR spectroscopic and microscopic measurements at the nanoscale will offer nearly universal means for detection of molecular substances and provide unique insights into elementary excitations in solids. The proposed S-SNIM will enable spectroscopy and imaging in the near/mid-IR region at cryogenic temperatures with spatial resolution down to 10 nanometers. Broader impact: The proposed instrumentation will significantly impact the research infrastructures at the local, regional, and national levels. Locally, more than 25 grad students and researchers affiliated with 9 research groups at UCSD will enhance their training and research. Regionally, a number of industrial partners will gain access to the micro-spectroscopy instrument. Nationally, the proposed instrumentation will reduce burden on oversubscribed synchrotron beamlines at national laboratories, whereas the commercialization of these instruments in collaboration with Agilent and industrial partners will help to maintain the US leadership in manufacturing state-of-the-art instrumentation for probing matter at the nanoscale. Educational activities include development of a new special-topics course, opportunities for interdisciplinary education and training of underrepresented groups. This latter involves outreach to middle and high school students at the UCSD Preuss School, recruitment and mentoring of graduate students and post-doctoral scholars, as well as of undergraduates in conjunction with CAMP: California Alliance for Minority Participation.
