Schematic setup of large cone-target simulation. (a) HYDRA simulation of low-intensity interaction after 1 ns; length scales indicated by white lines, subregion selected for PIC simulation schematically indicated by dotted black line. (b) Image of aberrated spot used for reconstruction of main pulse in 2D.
PIC simulations of cone interaction with preplasma; shown are Poynting flux along , density of “cold” electrons , and “hot” electrons . (a) Intrinsic preplasma case with 7.5 mJ and (b) 100 mJ preplasma case. The laser is incident from below.
Fully resolved collisional PIC simulation result, demonstrating that resistive MHD can be used to describe the fields generated by fast electrons. Shown are laser-cycle averages of electron density , electron temperature , and longitudinal electric field (thin black line, in background), and the value of the Ohmic field (thick red line, in foreground) computed from the current and Spitzer resistivity , see text, at time .
PIC vs PIC/hybrid simulation results for the case discussed in Fig. 3 at the same and reduced resolution. The interface between PIC and hybrid region is indicated by a dashed line.
Hybrid simulation of cone-wire target. Shown are cold electron density and Poynting flux along , electron temperature, and line-outs along at . The dotted line in (c) indicates the initial electron density before ionization.
Hybrid simulation of cone-wire target, (a) hot-electron density, (b) static electric fields, and (c) electron density distribution in wire, as indicated by dashed box in (a), with three slope temperatures fitted as labeled.
Hybrid simulation of cone-wire targets with different levels of preplasma. The left case corresponds to 10 mJ of prepulse energy, the right one to 100 mJ. Shown are hot-electron density, [(a) and (c)] Poynting flux, and [(b) and (d)] temperature.
