Abstract
In inertial confinement fusion (ICF) experiments, the growth of hydrodynamic instability occurred at the layer-to-layer interface of multilayer capsule is of the main importance to obtain ignition and high gain. In order to investigate and simulate the growth of hydrodynamic instability at “SG II”laser facility, we designed and fabricated a multi-layered shock wave tube (MSWT) in this article. The MSWT consisted of four functional units: planar polystyrene (CH) film, Al film with perturbation patterns, polyimide (PI) plastic and cylindrical carbonized-resorcinol–formaldehyde (CRF) aerogel, which were assembled into a cylindrical CH tube. The design, preparation process and assembly process of MSWT were detailed described. The assembly deviations and packaging material were discussed.
