Abstract

Summary form only given. We focus on the radiative characteristics and cooling rate as a function of the initial gas puff mass profile distribution. A benchmark test of the code will be made by comparisons with experimental results obtained on the DQ pulsed power generator. The experiments employed 8 cm and 12 cm diameter nozzles. One of the goals of this effort is to identify the gas puff load that minimize the development of RT instabilities during its implosion phase and optimize the corresponding emission characteristics and spectrum.
