Abstract
Ultrafast two-dimensional (2D) x-ray imaging with a temporal resolution bet ter than 10 ps is of great importance in diagnosing the final stages of the imploded core plasmas of inertial confinement fusion (ICF) targets. The mu lti-imaging x-ray streak camera (MIXS) has been one of such imaging techniq ues. Recently, we have proposed another scheme, a 2D sampling-image x-ray s treak camera method (2D-SIXS). In this scheme, a 2D image is sampled two di mensionally with a set of sampling points distributed regularly over the wh ole image on a cathode plate of an x-ray streak camera. The sampled image i s streaked, and then, reconstructed to form the time-resolved 2D images lik e movie pictures. In this article, we report results of our proof-of-princi ple experiments of 2D-SIXS scheme performed at Gekko-XII glass laser system . A gold-coated spherical target was irradiated by three beams (0.53 mu m) of Gekko-XII laser. Streaked data of 2D-SIXS were obtained and a series of time-resolved 2D x-ray images were successfully reconstructed. 2D-SIXS is s uitable for very fast, short-lived, and small x-ray sources such as a hot s park in the ICF plasma as well as short-pulse-laser-produced plasmas.
