Volume Ignition in Pellet Fusion

Awarded: NOK 0.10 mill.

We propose a novel method for reaching ignition conditions in ICF without the build-up of any instabilities, by implementing relativistic concepts not previously used in this field. Instead of the usual adiabtic compression and heating of a spherical fuel pellet using an array of lasers, our project proposal is to use a linear configuration with a flat target and only two lasers. In this way, using RFD, we can heat the target by rapid light absorption through rapid ignition. The detonation front will then become "time-like", which makes simultaneous, whole volume ignition possible. Then there is no time for instabilities to occur. This method is based on the fundamental theories of Taub (1948), with the correction by Csernai in 1987. New relativistic fluid dynamics methods, developed in the field of ultra-relativistic heavy ion reactions at CERN provide spin-offs for Inertial Confinement Fusion. The time-like behavior of the detonation front is only possible using relativistic energies, and this behavior is well known in Relativistic Heavy Ion Collisions, but never before used in ICF. In order to have uniform heating throughout the whole fuel volume, we "dope" the fuel target with golden nano-shells. The use of such Nano-Technology is also a completely novel concept in ICF. We will also study heavy ion induced fusion, which is relevant for FAIR in Darmstadt and FIAS in Frankfurt. The same rapid ignition and the uniform burning can be achieved by short accelerator bunch length focusing.
