2016 IEEE International Conference on Plasma Science (ICOPS)
Year: 2016 | Conference Paper |
The Near Vacuum Campaign on the National Ignition Facility has sparked an interest on the nature of the gold/carbon interface at high velocity (400 km/s), high electron temperature (2 keV), low-electron density (1e21). Indeed radiation-hydrodynamic simulations using the code HYDRA have been unable to accurately reproduce the experimental shape of the hot spot resulting from implosion driven in Nea...Show More

The HED 2-Shock implosion campaign was developed on the National Ignition Facility as a relatively robust and well-beha ved nearly one-dimensional, low convergence, symmetric platform by employing a very high foot temperature and a large case-to-capsule (hohlraum-to-capsule) ratio. The results of these experiments investigating capsule implosion phenomena such as interface hydrodynamic mixing, con...Show More

Laser facilities for fast ignition will require in excess of 50 kJ of short pulse laser energy. Based on the current contrast estimate for the NIF ARC laser system at LLNL, ignition scale systems will have pre-pulses at the ~J level. This will produce a large scale-length plasma inside the reentrant fast ignition cone that could significantly influence the generation and transport of hot electrons...Show More

We have developed a hybrid Ti:sapphire-Nd:glass laser system that produces more than 1.5 PW of peak power. The system has produced up to 680 J of energy on target at 1054 nm in a compressed 440/spl plusmn/20-fs pulse by use of 94-cm diffraction gratings. A focused irradiance of up to 6/spl times/10/sup 20/ W/cm/sup 2/ was achieved using an on-axis parabolic mirror and adaptive optic wavefront cont...Show More
