This paper documents the effects on confinement of introducing discrete limiters into the edge plasma of the ZT‐40M reversed‐field pinch (RFP) [Fusion Technol. 8, 1571 (1985)]. RFP confinement is not significantly degraded by appropriately design

The edge plasma of the ZT‐40M [Fusion Technol. 8, 1571 (1985)] reversed‐field pinch has been studied using a combination of three different plasma probes: a double‐swept Langmuir probe, an electrostatic energy analyzer, and a calorimeter–Lang

Eighth IEEE International Conference on Pulsed Power.
The Dual-Axis Radiographic HydroTest (DARHT) Facility is being designed to produce high-resolution flash radiographs of hydrodynamics experiments. Two 16- to 20-MeV linear induction accelerators (LIA), with an included angle of 900, are used to produ

Three limiter configurations were evaluated in the reversed-field pinch, ZT-40M. A bare graphite mushroom-shaped probe located in a pump port measured changes in the energy flux profiles resulting from three different limiter configurations. The firs

The present status of research on the ZT-40M Reversed-Field Pinch (RFP) will be described. RFP discharges have been sustained for times (27 ms) >> the classical resistive diffusion time, implying the existence of a flux-sustainment mechanism (''dynam
