Paper Abstract

A new target design has been proposed which displays a high gain at 1.3 MJ laser energy and improved Rayleigh-Taylor stability with a KrF laser system. The laser contrast ratio in this case is around 250 and the laser pulse lengths is around 28 ns. For a system like NIF, where the contrast ratio is limited to about 100, where no zooming is planned, where the laser pulse length is limited to less than 20 ns and 1/3 micrometers is the laser light wavelength, we have looked at targets using radiation preheat. We have designed targets for this application and investigated more fully the trade- off between gain and stability.
