Abstract:

We have performed short-pulse x-ray scattering measurements on laser-driven shock-compressed plastic samples in the warm dense matter regime, providing instantaneous snapshots of the system evolution. Time-resolved and angularly resolved scattered spectra sensitive to the correlation effects in the plasma show the appearance of short-range order within a few interionic separations. Comparison with radiation-hydrodynamic simulations indicates that the shocked plastic is compressed with a temperature of a few electron volts. These results are important for the understanding of the thermodynamic behavior of strongly correlated matter for conditions relevant to both laboratory astrophysics and inertial confinement fusion research. © 2009 The American Physical Society.

Design of a sub 100-femtosecond X-ray streak camera

Optics InfoBase Conference Papers (2009)

Authors:

B Li, PP Rajeev, G Gregori, M Benetou, B Dobson, A Cavalleri, L Pickworth, P Lau, P Jaanimagi, F Read, J Lynn, D Neely

Abstract:

The temporal resolution of existing streak cameras are limited by electron transit time dispersion. Here we present a state-of-art design compensating this to achieve a breakthrough of 100fs time resolution. © 2009 OSA/CLEO/IQEC 2009.
