Using magnetic levitation to produce cryogenic targets for inertial fusion energy: experiment and theory
We present experimental and theoretical studies of magnetic levitation of hydrogen gas bubble surrounded by liquid hydrogen confined in a semi-transparent spherical shell of 3 mm internal diameter. Such shells are used as targets for the Inertial Confinement Fusion (ICF), for which a homogeneous (within a few per-cent) layer of a hydrogen isotope should be deposited on the internal walls of the...
متن کاملModeling Laser Imprint for Inertial Confinement Fusion Targets
LLE Review, Volume 80 185 In inertial confinement fusion (ICF), a spherical shell filled with a DT-gas mixture is compressed to high densities and temperatures to achieve ignition condition.1 Degradation from spherical symmetry during the implosion, however, limits the achievable compression ratios and could quench the ignition. The main source of such asymmetry is hydrodynamic instabilities (s...
متن کاملHot-spot mix in ignition-scale inertial confinement fusion targets.
Mixing of plastic ablator material, doped with Cu and Ge dopants, deep into the hot spot of ignition-scale inertial confinement fusion implosions by hydrodynamic instabilities is diagnosed with x-ray spectroscopy on the National Ignition Facility. The amount of hot-spot mix mass is determined from the absolute brightness of the emergent Cu and Ge K-shell emission. The Cu and Ge dopants placed a...
متن کاملLongitudinal Tracking of Direct Drive Inertial Fusion Targets
Successful ignition of direct drive targets in an IFE power plant requires a reliable system for tracking the location of the target in flight and illuminating it by many separate laser beams with a high degree of precision. As part of a coordinated effort in the High Average Power Laser (HAPL) program, we have developed and tested an interferometric technique for measuring the position and vel...
متن کاملHeavy ion driven reactor-size double shell inertial fusion targets
Inertial Confinement Fusion (ICF) is considered as an alternative to Magnetic Confinement Fusion to achieve controlled thermonuclear fusion. The main goal is to exploit the energy released from thermonuclear fusion reactions to produce electric energy. Heavy ion beams were proposed in 1976 as one of the possible drivers in ICF. The method consists in igniting few milligrams of deuterium-tritium...
