Electron transport in cone targets in high intensity laser-plasma interaction

POSTER

Abstract

Copper cones targets of different roughnesses were irradiated with the Thor laser (0.5J, 40fs, 800nm, 7 micron focal spot, 3.10$^{19}$W/cm$^{2}$) at UT Austin. Hot electron transport in the tip has been diagnosed with Coherent Transition of Radiation (CTR). Progress at the NTF has been made and a new diagnostic is being designed to provide a CTR at both $\omega$ and 2 $\omega$. Results supported by simulations will present the current knowledge and trace a path to future progress.
