Stabilization and Confinement of Hot, Dense, High-Beta Plasma.

摘要

A calibrated, high-repetition rate 2-terawatt z-pinch (Zebra) was developed, and new z-pinch physics was investigated. Investigation of axial- shear-flow z-pinch stabilization was initiated, with experiments, computer modeling, and theory. An experiment on single wires driven by current prepulses similar to, and faster than, those at Z (SNL) found that faster rising pulses are much more effective at exploding single tungsten wires than Z-like pulses. Experiments on x-pinches driven at 900 kA characterized x-pinches in an almost unexplored regime.
