Evolution of spectrally discriminated spatial uniformity of linehyphen;shaped plasmas

摘要

A spacehyphen;resolved soft xhyphen;ray (SXR) transmission grating spectrometer and a SXR streak camera are used to investigate the evolution of spectrally discriminated spatial uniformity of linehyphen;shaped plasmas produced by uniform laser illumination in line focus. It is found that the spatial nonuniformity of SXR emissions and ion turbulence occur during optical laserrsquo;s heating. Various instabilities can be excited due to the long scale length in linehyphen;shaped plasmas to produce the phenomenon.
