Title: Increasing plasma parameters using sheared flow stabilization of a Z-pinch

Journal Article · · Physics of Plasmas
DOI:https://doi.org/10.1063/1.4977468· OSTI ID:1465207

The ZaP and ZaP-HD Flow Z-pinch experiments at the University of Washington have successfully demonstrated that sheared plasma flows can be used as a stabilization mechanism over a range of parameters that has not previously been accessible to long-lived Z-pinch configurations.
