A highly-ordered

hexagonally arranged alumina nanopore template was prepared by self-organized two-step anodization process of aluminium in oxalic acid solution. Highly parallel pores were obtained within domains of a few micrometers. Highly-ordered

parallel carbon nanotube arrays were successfully grown in the alumina template nanopores by chemical vapor deposition catalyzed by alumina itself. The nanotube arrays are suitable for channeling of particle beams. The structures of aluminium

alumina template and carbon nanotubes were characterized by scanning electron microscopy(SEM) and electron back scattered diffraction(EBSD). The growth mechanism and formation condition of both alumina template and carbon nanotube were discussed.
