HELIOS Benchmark Calculation: Radiation-Driven Capsule Implosion in Z-Pinch Dynamic Hohlraum
In this HELIOS benchmark simulation, a spherical capsule embedded in a low-density CH2 foam is imploded by an external radiation field. The parameters utilized in this benchmark simulation are taken from z-pinch-driven dynamic hohlraum experiments performed at the Z facility at Sandia National Laboratories [1]. The time-dependent hohlraum radiation field is constrained by on-axis XRD and bolome...
متن کاملIntegrated two-dimensional simulations of dynamic hohlraum driven inertial fusion capsule implosions
Simulations have been useful for improving the design of dynamic hohlraums for the purpose of imploding inertial fusion capsules S. A. Slutz, J. E. Bailey, G. A. Chandler et al., Phys. Plasmas 10, 1875 2003 . These design changes, which have resulted in capsule implosions with hot dense cores J. E. Bailey, G. A. Chandler, S. A. Slutz et al., Phys. Rev. Lett. 92, 085002 2004 and the production o...
متن کاملRadiating shock measurements in the Z-pinch dynamic hohlraum.
The Z-pinch dynamic hohlraum is an x-ray source for high energy-density physics studies that is heated by a radiating shock to radiation temperatures >200 eV. The time-dependent 300-400 eV electron temperature and 15-35 mg/cc density of this shock have been measured for the first time using space-resolved Si tracer spectroscopy. The shock x-ray emission is inferred from these measurements to ex...
متن کاملTarget design for high fusion yield with the double Z-pinch-driven hohlrauma..
A key demonstration on the path to inertial fusion energy is the achievement of high fusion yield !hundreds of MJ" and high target gain. Toward this goal, an indirect-drive high-yield inertial confinement fusion !ICF" target involving two Z-pinch x-ray sources heating a central secondary hohlraum is described by Hammer et al. #Phys. Plasmas 6, 2129 !1999"$. In subsequent research at Sandia Nati...
متن کاملHigh-Yield Z-Pinch Thermonuclear Neutron Source
Introduction: Neutron beams are useful for many applications, from noninvasive imaging and characterization of materials to producing medical isotopes and detecting hidden explosive devices. Some applications require high-energy neutrons created in fusion nuclear reactions between deuterium (D) and tritium (T). To achieve thermal fusion, deuterium or DT plasma must be heated to about 10 8 K, wh...
