Anshul Kogar

Anshul has been a frequent visitor to CHESS for almost a decade, where he has used both the A2 and C1 beamlines. As a graduate student user, he was trained in the usage of synchrotron facilities at CHESS. He has since also performed X-ray experiments at several different end stations at the APS at Argonne National Lab, where he has pursued, among other things, high-resolution inelastic X-ray scattering. To complement his synchrotron work, he has also developed an in-house lab-based experimental technique called momentum-resolved electron energy loss spectroscopy (M-EELS). This technique borrows ideas from X-ray facilities but instead uses electron beams to probe condensed phases of matter. Anshul sees the future of CHESS as a facility where graduate students and postdocs can gain valuable research experience in performing cutting-edge synchrotron experiments. These include diffuse scattering measurements, diffraction measurements, and spectroscopy measurements where the use of a beam with high flux but intermediate brightness is needed. For these kinds of experiments, a high brightness beam (as planned for the APS upgrade) is neither necessary nor warranted. CHESS will serve the needs of the scientific community that require novel instrumentation using beams in the intermediate brightness range.
