In fast ignition, the role of corn is very important to guide hot electrons to imploded core plasma for heating. It is concerned that hot electrons are scattered by high-Z plasma generated from gold cone target. This may cause the drop of the energy coupling of the heating laser to hot electrons. Therefore, low-Z materials are drawing attention as cone materials. Moreover, some simulation studies suggest the possibility for the hot electron beam guiding by the self-generated magnetic field by using pointed type cone (Tongari cone). In this study, we develop the method to fabricate an aluminum cone tip to attach the conventional gold cone in order to confirm above mentioned interesting characteristics of the low Z cone.
