Experience of micro-heterogeneous target fabrication to study energy transport in plasma near critical density
The influence of underdense polymer target with/without high-Z nanoparticles on laser radiation absorption and energy transport
Fabrication methods for low-density fine-structure (cell
size 1 m) 3-D networks of cellulose triacetate (TAC) are developed.
Target densities ranged 4-20 mg/cc, similar polymer structures were produced
both with no load and with high-Z cluster dopant with concentration up to
30%. Foams of varying density down to 0.25 plasma critical density at the
third harmonic of iodine laser wavelength are supplied for laser shots.
Experiments with underdense foam targets with and without clusters
irradiated on the PALS laser facility are analyzed preliminary, showing
strong influence of target structure on process of laser light absorption.
Heat and radiation transport in such targets are considered
