Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

Abstract: Electrodes that produce a uniform electric field across their surfaces are desired for a variety of high-voltage systems, including spark-gap switches and transversely excited atmospheric ...

Using the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical ...
