Absorption gratings can be fabricated by filling the grooves of a one-dimensional lattice structure with a high aspect ratio with X-ray absorbers, and the ultracentrifugal deposition method has been proposed as a low-cost and quick method for fabricating such gratings. In this method, a suspension of X-ray absorber particles is subjected to an ultracentrifuge to sediment the particles, which are then deposited in the grooves of a structure placed at the bottom of the suspension. In this experiment, we fabricated X-ray absorption gratings by the ultracentrifugal deposition method and attempted to melt the particles using an electric furnace in order to further improve the filling ratio.
