study of Equation of State (EOS) at high pressures is of interest for several fields of
Physics, in particular astrophysics, material science and inertial confinement fusion. The Laser
driven shock studies on various targets have been done with the 10 J/ 500 ps laser system. The
focused intensity at the target was 1013 to 1014
W/cm2. The shock velocity was measured by using an optical streak camera. We have used various thicknesses of Al foil and 10 μm gold foil targets.
Scaling of target velocity, with laser intensity has been done. The scaling of shock transit time
with the foil thickness has been done. It is observed that at laser intensity > 1
x1014 W/cm2 the
shock pressure measured from various target material are more than 10 Mbar. The scaling of
shock transit time with target thickness has been measure. Also the scaling of shock velocity with
laser intensity has been done for Aluminium and gold targets. The experimental observations are
seen to match well with the simulations. |
