Neutron Imaging with Bubble Chambers for Inertial Confinement Fusion
One of the main methods to obtain energy from controlled thermonuclear fusion is inertial confinement fusion (ICF), a process where nuclear fusion reactions are initiated by heating and compressing a fuel target, typically in the form of a pellet that contains deuterium and tritium, relying on the inertia of the fuel mass to provide confinement. In inertial confinement fusion experiments, it is...
متن کاملAperture tolerances for neutron-imaging systems in inertial confinement fusion.
Neutron-imaging systems are being considered as an ignition diagnostic for the National Ignition Facility (NIF) [Hogan et al., Nucl. Fusion 41, 567 (2001)]. Given the importance of these systems, a neutron-imaging design tool is being used to quantify the effects of aperture fabrication and alignment tolerances on reconstructed neutron images for inertial confinement fusion. The simulations ind...
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 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 کاملInverse Braking Radiation and Resonance Absorption in Corona Plasmas of Inertial Confinement Fusion
Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...
