Time-resolved measurement of coronal temperature and line-intensity profiles in laser-produced plasmas
Abstract
Time-resolved electron temperature and line-intensity profiles in laser-produced plasmas have been measured for the first time with an x-ray framing camera. Temperature profiles measured from the slope of the free-bound recombination continuum in AlXIII ions are significantly lower than hydrodynamic model calculations. Simultaneous interferometric density measurements are in much closer agreement with computer simulations. Spectral line-intensity profiles have also been measured and cannot be described by standard collisional radiative equilibrium models.
