Ultrafast compression of graphite observed with sub-100 fs time resolution diffraction at LCLS
ORAL
Abstract
We will present sub-100 fs time resolution pulsed x-ray diffraction measurements of rapidly compressed highly oriented pyrolytic graphite along its basal plane at the Materials under Extreme Conditions (MEC) sector of the Linac Coherent Light Source (LCLS). These experiments explore the possibility of rapid (100 ps scale) material transformations occurring in materials under very highly anisotropic compression conditions. Under such conditions, non-equilibrium mechanisms may play a role in the transformation process. We will present experimental results and simulations which explore this possibility.
