Abstract
The first infrared microspectroscopy beamline at the Louisiana State University, Center for Advanced Microstructures and Devices (LSU-CAMD) has been constructed and dedicated to investigation of samples from various disciplines including chemistry, geology, biology, and material sciences. The beamline comprises a simple optical configuration. A planar and toroidal mirror pair collects 50 and 15 mrad synchrotron radiation in horizontal and vertical directions, respectively, and focuses the beam through a diamond window located outside of the shielding wall. This focus acts as a new source point for the rest of the optical systems. The synchrotron beam spot size of 35 μm and 12 μm is measured in the x and y direction of the sample stage position of the microscope. This small beam spot has a superior brightness compared to conventional IR sources and allows spatially resolved measurements with very good signal/noise ratio. Compared to a conventional thermal source, synchrotron radiation provides 30 times better intensity and a two orders of magnitude greater signal/noise ratio when measuring with microscope aperture size of 15 × 15 μm . The results of the studies on the fungus-plant interaction with its resultant effects on the healthy leaves, and bacterial growth process in the crystallization of gordaite, a mineral, are presented. © 2007 American Institute of Physics. 2
