Preliminary Cryogenic Layering by the Infrared Heating Method Modified with Cone Temperature Control for the Polystyrene Shell FIREX Target

The infrared (IR) heating method for a central ignition target with spherical symmetry is modified the axisymmetric Fast Ignition Realization EXperiment (FIREX) target. challenge that FIREX pretends to be thermally shell. Our previous simulation studies (A. Iwamoto et al., Fusion Sci. Technol. 56, 427 (2009), A. J. Phys.: Conf. Ser. 244, 032039 (2010)) have shown combination of volumetric in fuel and cone temperature control has potential finish uniform layer. We developed IR system, dedicated target, exclusive control. ability solid layering was examined by using an 826 µm polystyrene (PS) shell gold 1.2 mm length instead 500 easy observation. system could profile layer PS Eventually, best sphericity 92% formed, RMS roughness inner surface 44 - 49 modes 1 100 14 26 5 100.
