Z Machine

Eight years ago, the Z machine startled the world when a technical advance enabled the machine?s power output to rise the way investors want their stock graphs to move: nearly straight up. Output for Sandia?s pulsed power projects, which had increased only slowly for more than a decade, rose dramatically. For Z, just coming on line, an expected usable output of 50 terawatts rose over the next two years to 230 terawatts. This made the machine not only more valuable as a data provider for nuclear weapons simulations but also showed that z-pinches were a possible candidate for peacetime fusion.
