Descripción
We present results from an experimental characterization of fast electron transport in high density plasmas created by 1D shock wave compression.TheK fluorescence from a Culayer embedded in Alor CHfoiltargets is measured. Weuselonglaser pulses (LP) with 180 J, 1.5ns, 0.53 µm to compress the foils by shock wave propagationto2-3 times their solid density and heat themto¿4eV (close to the Fermi temperature). Acounter - propagatinghigh-intensity short laser pulse(SP), with40J,1ps,5×1019Wcm¿2, generates intense current so ffastelectrons which propagate throught hedeep regions of the target just before shock break through. The results are compared to the uncompressed, solid density case (with out the LP beam). The complete set of measurements is compared to numerical results, including 2D hydrodynamic description of the compression and pre-pulsee ects, 2DPIC simulations of the SP beam interactionand both hybrid and PIC simulations of the electron transport in the target dept hands heaths. In the case of then on-compressed targets we need to take fast electron reflux in into account to reproduce the experimental results. By exploring the domain of warm temperatures, we identify a regime for the incident fast electron current density, 1010
