Abstract
Two X-ray backlighting techniques have been developed to diagnose the laser-imploded fusion targets. One is the multi-color backlighting for the targets consisting of various materials. The implosion dynamics of a double shell target, which consisted of a parylene outer shell and a glass inner shell, was investigated by using 1.2 keV and 2.6 keV X-ray source and a couple of pinhole cameras. The other is the application of a point X-ray source to the plasma diagnostics. It has many advantages in comparison with the usual back-lighting with a extended source. The new backlighting methods were tested through (1) a simple backlighting without any X-ray optics, (2) the measurement of X-ray refraction due to steep-gradient, high-density plasma, and (3) the spectrally resolved backlighting of planar targets combining with a flat crystal spectrometer.
