Magnetized Target Fusion


MTF 2001 Photos



LANL is working on a new experimental program in Magnetized Target Fusion (MTF).  Our embodiment of MTF involves compressing a few-centimeter scale magnetized (~ 50-100 kilogauss) target plasma with a fast-moving metal wall. We believe it has the potential to create a burning fusion plasma in the laboratory for a very low capital cost.  In FY00-03 experiments are aimed at demonstrating production of a suitable target plasma. In FY04-05 we will conduct translation tests, and in follow-on experiments, not yet funded, the plasma target will be imploded on the Shiva-Star pulsed power facility at the Air Force Research Laboratory in Albuquerque, NM, using deuterium fuel for the plasma. We are aiming at achieving a 10:1 cylindrical compression of the plasma, using liner compression technology at a few megajoules of energy to provide the power to adiabatically heat the plasma to fusion-relevant conditions. 

The new plasma injector experiment for MTF at LANL, named FRX-L (field reversed experiment - liner) is operational (9/2001), and makes static (non-translated) high energy FRC plasmas.
