Fabrication of patterned film-foam composite planar target

The Br doped polystyrene film with the sine wave modulated pattern was fabricated and the composite planar target comprising patterned film and foam was also explored by casting the foam solution on the patterned film. Attempts to make composite planar target with sine wave pattern were be discussed and the profile was characterized by the Form Talysurf Series 2 and microscope. The target was intended for Rayleigh-Taylor instabilities.The study indicates that it is easy to controll the film thickness and foam density of the target and to fabricate and assemble the target．
