New paradigm : Controlling Initiation Phase is Necessary for Optimization of Wire-Array z-Pinch Performance

摘要

The initiation phase of a wire-array is of paramount importance for achieving an axially homogeneous z-pinch and reproducible, high x-ray power. The significance of wire-array initiation during current prepulse for z-pinch performance has not been widely acknowledged. To achieve new levels of progress in wire-array z-pinch physics it is necessary to accept the importance of initiation physics, and to implement diagnostics of array initiation. This communication provides a brief review pointing out the need to control the initiation phase of a wire array for optimum z-pinch performance, and suggesting why multi-MA wire-array z-pinch experiments fail to meet MHD expectations.
