    Magneto-Inertial Fusion

    Magneto‐Inertial Fusion LA‐UR‐14‐23844 G. Wurden, S. Hsu, T. Intrator (LANL), C. Grabowski, J. Degnan, M. Domonkos, P. Turchi (AFRL), M. Herrmann, D. Sinars, M. Campbell (Sandia), R. Betti (U Rochester), D. Ryutov (LLNL), B. Bauer, I. Lindemuth, R. Siemon (UNV, Reno), R. Miller (Decysive Systems), M. Laberge, M. Delage (General Fusion) Description Magneto-inertial fusion (MIF) (aka, magnetized target fusion, or MagLIF) is an approach to fusion that combines the compressional heating of ICF with the magnetically reduced thermal transport and magnetically enhanced alpha heating of MCF [1]. From an MCF perspective, the higher density, shorter confinement times, and compressional heating as the dominant heating mechanism reduce the impact of instabilities. From an ICF perspective, the primary benefits are potentially orders of magnitude reduction in the difficult to achieve ρr parameter (areal density), and potentially significant reduction in velocity requirements and hydrodynamic instabilities for compression drivers. In fact, ignition becomes theoretically possible from ρr≤0.01 g/cm2 up to conventional ICF values of ρr~1.0 g/cm2, and as in MCF, Br rather than ρr becomes the key figure-of-merit for ignition because of the enhanced alpha deposition. Within the lower-ρr parameter space, MIF exploits lower required implosion velocities (2–100 km/s, compared to the ICF minimum of 350-400 km/s) allowing the use of much more efficient (η~0.3) pulsed power drivers, while at the highest (i.e., ICF) end of the ρr range, both higher gain G at a given implosion velocity as well as lower implosion velocity and reduced hydrodynamic instabilities are theoretically possible.

This article is published with open access at Springerlink.com Abstract In this community white paper, we describe an fusion (MCF). From an MCF perspective, the higher density, approach to achieving fusion which employs a hybrid of shorter confinement times, and compressional heating as the elements from the traditional magnetic and inertial fusion dominant heating mechanism reduce the impact of instabil- concepts, called magneto-inertial fusion (MIF).
