Shock ignition target design for inertial fusion energy
Continuing work in the design of shock ignition targets is described. Because of reduced implosion velocity requirements, low target adiabats, and efficient drive by short wavelength lasers, these targets produce high gain (> 100) at laser energies well below 1 megajoule. Effects of hydrodynamic instabilities like Rayleigh-Taylor or RichtmyerMeshkov are greatly reduced in these low-aspect ratio...
متن کاملSpherical Strong-Shock generation for Shock-ignition inertial fuSion
LLE Review, Volume 141 48 Introduction Shock ignition (SI)1–5 is an advanced concept in inertial confinement fusion (ICF)6 that is very promising and has the potential to provide significantly higher gains than conventional hot-spot ignition.7 SI is a two-step process where the fuel compression and ignition phases are separated by applying a highly shaped laser pulse with a duration of several ...
متن کاملBasic Principles of Direct-Drive Ignition Target Design
LLE Review, Volume 106 83 Introduction Inertial confinement fusion (ICF) is an approach to fusion that relies on the inertia of the fuel mass to provide confinement. The confined fuel must reach a high temperature and density to produce enough D + T $ a(3.5 MeV) + n(14.1 MeV) reactions so that the total energy released is much larger than the driver energy required to compress the fuel. The cap...
متن کاملDirect-Drive Target Designs for the National Ignition Facility
LLE Review, Volume 79 121 The National Ignition Facility (NIF) is currently under construction at Lawrence Livermore National Laboratory (LLNL). One of the primary missions of the NIF is to achieve fusion ignition by means of inertial confinement fusion (ICF). Two main approaches have been considered for achieving thermonuclear yield in ICF. The first approach, known as indirectdrive ICF,1 encl...
متن کاملLocal Ignition in Carbon/Oxygen White Dwarfs – I: One-zone Ignition and Spherical Shock Ignition of Detonations
The details of ignition of Type Ia supernovae remain fuzzy, despite the importance of this input for any large-scale model of the final explosion. Here, we begin a process of understanding the ignition of these hotspots by examining the burning of one zone of material, and then investigate the ignition of a detonation due to rapid heating at single point. We numerically measure the ignition del...
