Heat transport measurement in ablation plasms with background corrected OTS
ORAL
Abstract
Particle transport in laser ablated plasmas can be strongly influenced by non-Maxwellian features of the
electron distribution function. These features are strongest in high Z plasmas (1) , but these plasmas also
have the highest self emission, making detailed Thomson Scattering measurements difficult. Using a
Wollaston prism to make a novel background subtraction system based on light polarization (2) , we measure
the effects on electron landau damping and Langmuir waves of non-thermal Au plasmas with non-local
heat transport.
