Helium-Hydrogen filled targets on Nova
Abstract
Over the last several years, many experiments have been performed on Nova to evaluate backscattering instabilities for plasma conditions similar to those expected on the Laser MegaJoule (LMJ) or the National Ignition Facility (NIF). In particular, the appropriate electron densities and temperatures have been accessed using Carbon-Hydrogen plasmas^1. However, in order to achieve the LMJ/NIF like ion damping on Nova, targets with helium-hydrogen gas fills must be employed. We will present helium-hydrogen targets designed to achieve the appropriate conditions for emulating LMJ/NIF conditions. Designs for both confined systems, such as hohlraums, as well as unconfined systems, such as gasbags, will be presented. ^1B.J. MacGowan et al , Phys. Plasmas. 3, 2029 (1996)
