A Step Forward for Fusion

A Step Forward for Fusion: Sandia's MagLIF technique is similar to NIF's in that it rapidly crushes its fuel—a process known as inertial confinement fusion. But to do it, MagLIF uses a magnetic pulse rather than lasers. The target in MagLIF is a tiny cylinder about 7 millimeters in diameter; it's made of beryllium and filled with deuterium and tritium. The cylinder, known as a liner, is connected to Sandia's vast electrical pulse generator (called the Z machine), which can deliver 26 million amps in a pulse lasting milliseconds or less...
 Sandia researcher Steve Slutz led a team that investigated various enhancements through computer simulations of the process. In a paper published in Physics of Plasmas in 2010, the team predicted that break-even could be reached with three enhancements...
