Direct-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 کاملThe saturn target for polar direct drive on the national ignition facility.
A new target design concept is proposed for direct-drive implosions while the National Ignition Facility is in its initial, indirect-drive configuration. It differs from earlier "polar-direct-drive" designs by adding a low-Z ring around the capsule equator. Refraction in the plasma formed around this ring permits time-dependent tuning of the capsule drive uniformity. An optimized simulation sho...
متن کاملHigh-Gain Direct-Drive Target Designs for the National Ignition Facility
LLE Review, Volume 88 183 Introduction Direct drive1 offers the potential of higher target gain for the National Ignition Facility (NIF)2 than indirect drive.3 Directdrive targets have been designed that reach a gain of 45 in onedimensional (1-D) simulations using primarily a pure cryogenic DT shell driven on an isentrope where the pressure is three times the Fermi-degenerate pressure (α = 3). ...
متن کاملTarget diagnostic control system implementation for the National Ignition Facility (invited).
The extreme physics of targets shocked by NIF's 192-beam laser is observed by a diverse suite of diagnostics. Many diagnostics are being developed by collaborators at other sites, but ad hoc controls could lead to unreliable and costly operations. A diagnostic control system (DCS) framework for both hardware and software facilitates development and eases integration. Each complex diagnostic typ...
متن کاملPolar Direct Drive on the National Ignition Facility
212 LLE Review, Volume 96 Introduction Recent advances in direct-drive target design have enhanced target performance beyond that achieved in the original baseline ignition design.1 This substantially increases the probability of achieving moderate to high direct-drive target gain on the National Ignition Facility (NIF). The baseline direct-drive design for the NIF is itself very attractive. It...
