Ablation Stability of Laser-Driven Implosions

Structure and Scaling Laws of Laser-Driven Ablative implosions

A stationary, spherical flow model gives the form of laserdriven ablation fronts and scaling laws for the dependence of Implosion parameters on laser wavelength, pusher atomic number, and other input quantities. One of the major deficiencies of the theory of laser-driven implosions has been the lack of even approximate analytic relationships between the specified parameters, material descriptio...

Fusion yield enhancement in magnetized laser-driven implosions.

Enhancement of the ion temperature and fusion yield has been observed in magnetized laser-driven inertial confinement fusion implosions on the OMEGA Laser Facility. A spherical CH target with a 10 atm D2 gas fill was imploded in a polar-drive configuration. A magnetic field of 80 kG was embedded in the target and was subsequently trapped and compressed by the imploding conductive plasma. As a r...

Study of laser ablation using nano-second laser pulses

 In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...

In-Flight Measurements of Capsule Adiabats in Laser Driven Spherical Implosions

Simulations of Diagnostic Emission due to Fuel-Pusher Mixing in Laser-Driven Implosions

It is important to develop diagnostics of the Rayleigh-Taylor instability that occurs during the deceleration phase of inertialconfinement-fusion capsule implosions because this instability is a crucial factor limiting the capsule performance.1 To simulate the effects of this instability and to assess possible diagnostic techniques, a mix model has been added to the one-dimensional (1-D) hydroc...
