Always nice to get the paper in just under the wire before the new year...

This technique just does not appeal to me. Too big, too complex.

Fusion instabilities lessened by unexpected effect

[D Tibbets]

I wonder if this magnetic field applied to the Z- pinch is similar to the mild magnetic field that apparently helps the DPF .

The initial motivation for adding the axial B-field was to inhibit energy losses from electron and ion transport out of the fuel. They preheat the fuel with a laser fired at the ends of the cylinder, MHD-freeze the axial B-field into the fuel plasma, then zap the whole thing with the big Z-pinch, which crushes the liner around the fuel.

Per Axil's cite above, the inhibition of Rayleigh-Taylor instabilities is a bit of a happy accident.

Sandia has published new MagLIF results. They have achieved 10E12 neutrons/pulse from a deuterium plasma. If they would have used a deuterium-tritium plasma then the expected neutron flux would have been 10E14. Break even would require reaching 10E16 neutrons/pulse. The Sandia press release is here https://share.sandia.gov/news/resources ... ag_fusion/.
