Experimental observation of ion correlation in a strongly coupled laser produced plasma

Experimental observation of ion correlation in a strongly coupled laser produced plasma
Experimental observation of ion correlation in a strongly coupled laser produced plasma
We present what we believe are the first experimental observations of ion correlation effects in a dense plasma. The plasma is produced in aluminum by colliding shocks driven by high-power laser beams. Computer simulations suggest that a peak temperature of over 1 eV and densities of several times that of solid are produced. Short-range order within the plasma is observed by means of the extended x-ray-absorption fine-structure (EXAFS) spectrum of the aluminum K absorption edge. Densities measured from the EXAFS spectrum are in reasonable agreement with the computer predictions.

Abstract

We present what we believe are the first experimental observations of ion correlation effects in a dense plasma. The plasma is produced in aluminum by colliding shocks driven by high-power laser beams. Computer simulations suggest that a peak temperature of over 1 eV and densities of several times that of solid are produced. Short-range order within the plasma is observed by means of the extended x-ray-absorption fine-structure (EXAFS) spectrum of the aluminum K absorption edge. Densities measured from the EXAFS spectrum are in reasonable agreement with the computer predictions.
