This is the Power Point presentation given by Dr. Scott C. Hsu of the Los Alamos National Laboratories, NM at the ARPA-E Fusion Workshop in Berkeley, CA, in 2013. It explains what a Standoff Magneto-Inertial Fusion Reactor is, how it would work, what are the advantages of that design, what the design and maintenance challenges are, and what the cost and timeline is expected to be for this type of fusion reactor to be ready for commercial use.
Summary
Standoff embodiment of MIF avoids destroying significant mass per shot
– Allows for higher repetition rate, cheaper and faster R&D development path, simpler reactor engineering, and better power-plant economics
– More attractive & plausible to potential sponsors/investors
Plasma liner driven MIF has many attractive features:
– Higher implosion velocity than most liner-driven approaches
– Potential for liner profile shaping and multi-layered structure
– Magnetized target could be formed separately or in situ (more options for risk mitigation)
– Many possible sources could potentially be used to form imploding plasma liners (can benefit from transformative new technologies)
– Potential compatibility with thick liquid wall or presently available plasma-facingcomponent (PFC) materials (avoids multi-$B, multi-decadal material development effort ßserious Achilles heel of fusion energy development)
– Plasma guns are economic candidate sources with many possible technological
spinoffs
