The Z-machine at Sandia National Laboratory, a former dark horse among accelerators meant to produce conditions required for nuclear fusion, is doing much better now, thank you. Researchers increased the machine's X-ray power output by nearly 10 times in the last two years. The most recent advance resulted in an output X-ray power of 290 trillion watts--about 80 times the entire world's output of electricity. The increased power will be a major contribution to the Department of Energy's (DOE) science-based approach to stockpile stewardship. This program dictates that DOE must use giant computing and laboratory experimentsto sustain the nation's nuclear stockpile without above- or below-ground tests. FAX (505) 844-6367.
