Target area for Nova upgrade: Containing ignition and beyond
- Lawrence Livermore National Lab., CA (United States)
- Los Alamos National Lab., NM (United States)
The Lawrence Livermore National Laboratory (LLNL) is developing a conceptual design for upgrading the Nova laser from {approximately} 50 kJ to {approximately} 1.8 MJ of laser energy at a wavelength of 351 nm. Anticipated target performance includes achieving ignition and possibly fusion yields to 20 MJ. The target area design represents a unique challenge since it will be operating in a regime where first wall ablation and optics damage are major issues for the first time in an ICF facility. Here we describe potential performance criteria for the facility and anticipated yield-dependent x-ray, neutron, shrapnel, and debris environments. We also briefly describe the different systems that make up the target area and discuss some of the design issues. The insignificant environmental impact Nova Upgrade (NU) operations is anticipated to have on the laboratory and surrounding area is discussed. Finally, alternate design options are described along with their potential benefits.
