Diagnosis of indirectly driven double shell targets with point-projection hard x-ray radiography
We present an application of short-pulse laser-generated hard x rays for the diagnosis of indirectly driven double shell targets.Cone-inserted double shell targets were imploded through an indirect drive approach on the upgraded SG-Ⅱ laser facility.Then,based on the point-projection hard x-ray radiography technique,time-resolved radiography of the double shell targets,including that of their near-peak compression,were obtained.The backlighter source was created by the interactions of a high-intensity short pulsed laser with a metal microwire target.Images of the target near peak compression were obtained with an Au microwire.In addition,radiation hydrodynamic simulations were performed,and the target evolution obtained agrees well with the experimental results.Using the radiographic images,areal densities of the targets were evaluated.
