Magnetized Target Fusion at General Fusion – SOFE 2017

Presentation Abstract

Speaker: Dr. Michel Laberge (General Fusion): Magnetized Target Fusion (MTF) involves rapidly compressing an initial magnetically confined plasma by >300X volume compression. If near adiabatic compression is achieved, the final plasma can be heated to > 10 keV, and confined inertially to produce interesting fusion energy gain. General Fusion is developing a compression system using pneumatic pistons to collapse a cavity formed in liquid lead-lithium, heating a plasma target such as a spheromak or spherical toroid trapped in the cavity.  With a low-cost driver, straightforward heat extraction, good tritium breeding ratio and excellent neutron protection, the concept is promising as a practical power plant. We will review the plasma formation and compression results achieved so far and our plans moving forwards. Work on the compression system will also be described.
