Equation of State Data for Iron at Pressures beyond 10 Mbar

Abstract: We present equation of state points for iron, in the pressure range 10 -45 Mbar, the first obtained with laser-driven shock waves. The experiment has been performed with the high energy laser Phebus, optically smoothed with Kinoform phase plates. Our results double the set of existing experimental data at very high pressures showing good agreement with the predictions of the quotidian equation of state model and with previous results.

“…National Ignition Facilities (NIF) being constructed in LLNL is going to introduce KPP to smooth 192 laser beams [1,3] . The smoothing methods for other lasers include: LULI laser in France and HELEN laser in UK adopted PZP [24] , Gekko XII laser of Osaka University in Japan used SSD for triple-frequency main beams and RPP for double-frequency backlighting beams, Phebus laser in France applied KPP [26] , and Pharos laser in Naval Research Laboratory (NRL) usually put to use ISI. The effects of ISI on Filament instability, SRS and SBS were experimentally investigated in NRL, and it has been confirmed that ISI can restrain the nonlinear instabilities [27,28] .…”

“…Equation of state (EOS) study at high pressure is physically important in laser inertial confinement fusion (ICF) [1][2][3][4][5]. The typical method for determining EOS points is based on the impedance-matching technique by measuring the shock velocity simultaneously using a double-step target.…”

“…It has been introduced by researchers from Los Alamos [33], and later, it has been mainly used for experiments relative to laser-driven shock and studies of materials at extreme pressures [34,35]. In this context, it has found recent applications for shock-timing in the context of implosion experiments on the National Ignition Facility [36].…”
