First phase commissioning of high pressure XAFS setup at ED-XAFS beamline, Indus-2 synchrotron radiation source, India

摘要

In this work, we report the first-phase commissioning of High Pressure setup at XAFS beamline (Bl-08) of Indus-2. This involved installation of vertically focusing bendable elliptical mirror to obtain～50 μm spot size, as required for Diamond Anvil Cell-based High Pressure XAFS experiment. We present details of the mirror alignment procedure, observed deviations from design goals and suggestions for improvement. We provide realistic estimate of the kind of experiments that can be performed in the current setup.
