Chris Jacobsen's work is aimed at the development and applications of high resolution X-ray imaging modalities. He, in collaboration with Professor Kirz and their students, built several scanning transmission X-ray microscopes which make use of two beamlines at the National Synchrotron Light Source at nearby Brookhaven National Laboratory. These microscopes use microfabricated diffracted optics (zone plates) to focus the bright beam of X-rays to a 50 nm spot which is used to explore the specimen. Chemical and elemental information is gained using absorption spectroscopy at any desired location. Wet specimens up to 10 microns thick may be examined at room temperature or in a frozen hydrated form at liquid nitrogen temperature to reduce radiation damage. Jacobsen was a Presidential Faculty Fellow (NSF/White House, 1992-1997), and received the International Dennis Gabor Award in 1996.
