Abstract

Abstract

The polystyrene (CH)/carbonized resorcinol formaldehyde (CRF), CRF/SiO2, CH/Al dual-layer perturbation targets for ICF resolved experiment were investigated. The CRF aerogel sheets with a density of 250 and 800 mg/cm3 were synthesized by sol-gel process. As the seed of the growth of hydrodynamic instability, the perturbation patterns were introduced onto the surface of CRF aerogel sheets and Al foil by laser micro-machining process. The CH films were directly coated on the patterned surface of CRF aerogel sheets(250 mg/cm3) and Al foil by spin-coating process while the SiO2 aerogel sheet was prepared on the CRF aerogel sheets(800 mg/cm3) by sol-gel process. The target parameters of CH/CRF, CRF/SiO2 and CH/Al dual-layer perturbation target were characterized by electro-balance, scanning electron microscope, tool microscope and surface profiler etc. The results indicated that the dual-layer perturbation target had good combination with clear interfaces, the perturbation patterns in the interfaces were sine, while the parameters were precisely measured.
