Abstract
Walter Greiner was one of the first physicists using Relativistic Fluid Dynamics for High Energy Nuclear Reactions. The present Inertial Confinement Fusion research and development is hindered by hydrodynamic instabilities, occurring at the intense compression of the target fuel by energetic laser beams. The suggested method combines recent advances in two fields: detonations in relativistic fluid dynamics and radiative energy deposition by plasmonic nano-shells. The compression of the target can be negligible and a laser pulse achieves rapid volume ignition, which is as short as the penetration time of the light across the pellet. The reflectivity of the target can be made negligible, and the absorptivity can be increased by one or two orders of magnitude using plasmonic nanoshells embedded in the target fuel. Thus, higher ignition temperature can be achieved with modest compression. The short light pulse can heat most of the interior of the target to the ignition temperature simultaneously. This prevents the development of any kind of instability, which would prevent complete ignition or transition of the target.
Highlights
Fusion energy production is a long-term goal of human society, which provides massive energy production with limited use of space, smallest amount of fuel and negligible waste! We address one of the two major directions of this research and development the Inertial Confinement Fusion (ICF)
This research reached a stage where the energy production is verified at the National Ignition Facility (NIF) in the Lawrence Livermore National Lab (LLNL) in USA, but the progress is slow and not satisfactory
We envisage a major change in the direction of this research with a fundamentally different approach. These are based on two novel discoveries in fundamental research: (1) Relativistic Fluid Dynamics is well studied in Relativistic Heavy Ion Reactions, including the burning of Quark Gluon Plasma (QGP), and in (2) Nano plasmonics, where light absorption is increased by one or two orders of magnitude with embedding resonant golden nano-shells into the target material
Summary
The primary objective is to develop the theoretical foundation for achieving ignition of the Deuterium-Tritium (DT) ignition fuel in Inertial Confinement Fusion, using a linear configuration, through implementation of concepts from Relativistic Fluid Dynamics (RFD) and Nano-Technology. These methods will be extended to heavy ion induced fusion. In the field of ICF research and all standard fluid dynamical applications, these are not known Up to now, this methodology is only used in ultra-relativistic heavy ion physics. We are going to use this methodology, Relativistic Fluid Dynamics, to develop a new technology This interdisciplinary approach is a spin-off of the high-energy fundamental research on the Earth. The present project plan is to study and improve the present ICF technology using the presented methodology and results of fundamental research
