Abstract
This paper presents design calculations for experiments that measure electron densities of laser heated hohlraums with soft-x-ray moiré deflectometry. Hydrodynamical simulations of the hohlraums are analyzed to obtain deflection angles of the probing beam and x-ray emission from the hohlraum. The deflection angles and resulting moiré fringe shifts and fringe contrast are predicted to be sufficient to infer electron-density gradients from measurements. In addition, the self-emission is found to be much lower than that of the probing laser beam, giving a good signal-to-noise ratio. In conclusion, moiré deflectometry with soft-x-ray lasers has the potential to give valuable information about the electron density in laser driven hohlraums.
