High density, high magnetic field concepts for compact fusion reactors

PDF Version Also Available for Download.

Description

During the past year, several concepts concerned with dense plasma fusion systems have been theoretically/numerically re-examined at LLNL, with a conclusion that they may become strong candidates for future alternatives research programs. A common feature of these schemes is that they employ (a) plasmas with densities ranging from {approximately}10{sup 16} cm{sup {minus}3} up to ICF-like densities ({approximately} 10{sup 26} cm{sup {minus}3}) and (b) magnetic fields. Their salient feature is also that, if successful, they would give rise to a compact and inexpensive reactor. Their compactness means also that the proof-of-principle experiment will be relatively inexpensive; the same is true for ... continued below

Description

During the past year, several concepts concerned with dense plasma fusion systems have been theoretically/numerically re-examined at LLNL, with a conclusion that they may become strong candidates for future alternatives research programs. A common feature of these schemes is that they employ (a) plasmas with densities ranging from {approximately}10{sup 16} cm{sup {minus}3} up to ICF-like densities ({approximately} 10{sup 26} cm{sup {minus}3}) and (b) magnetic fields. Their salient feature is also that, if successful, they would give rise to a compact and inexpensive reactor. Their compactness means also that the proof-of-principle experiment will be relatively inexpensive; the same is true for the developmental cost. Specifically, the authors consider the following concepts: (1) liner implosion of the closed-field-line configurations; (2) flow-through pinch; (3) magnetic ignition of inertial fusion. Although the first two concepts have been known in some form for a decade or so, new developments in fusion-related science and technology (e.g., direct experimental demonstration of a high-convergence 3D liner implosion and theoretical identification of a strong favorable effect of the shear flows on the stability of the pinches) certainly make them much more attractive than before. The third concept that emerged during last one or two years, also relies on a great progress in the understanding of the properties of high-density magnetized plasma. A brief description of each concept is given here.
