TL;DR: Fusion power has been increased by a factor of 3 in DIII-D by tailoring the pressure profile to avoid the kink instability in H-mode plasmas by controlling the plasma pressure profile width.
Journal ArticleDOI

TL;DR: In this article, a low-density CH foam that is wicked with solid DT and over-coated with a thin high-Z layer is used to achieve repetitive first light.
Journal ArticleDOI
The investigation of high intensity laser driven micro neutron sources for fusion materials research at high fluence
L.J. Perkins,B. G. Logan,M. D. Rosen,Michael D. Perry,T. Diaz de la Rubia,Nasr M. Ghoniem,Todd Ditmire,P. T. Springer,Scott Wilks +8 more
TL;DR: In this paper, the authors investigated the application of fast pulse, high intensity laser to drive low cost DT point neutron sources for fusion materials testing at high ux/uence. But the authors focused on the laser-plasma interaction physics and resulting neutron production, and the materials science required to validate computational damage models utilizing 100 dpa irradiation of such specimens.
Journal ArticleDOI
Shock ignition of thermonuclear fuel: principles and modelling
Stefano Atzeni,Xavier Ribeyre,Guy Schurtz,Andrew J. Schmitt,B. Canaud,Riccardo Betti,L.J. Perkins +6 more
TL;DR: In this article, the authors present an approach to direct-drive inertial confinement fusion (ICF) in which the stages of compression and hot spot formation are partly separated, and show potentials for high gain at laser energies below 1?MJ, and could be tested on the National Ignition Facility or Laser MegaJoule.
Journal ArticleDOI

TL;DR: The scientific justification for this work is a family of target designs (simulations) that show that direct drive has the potential to provide the high gains needed for a pure-fusion power plant.
