Generation of ultra-high acceleration field for new extreme condition science

Strong acceleration field is expected to realize the sedimentation of even atoms, or to create a chemically nonequilibrium state in condensed matter(metals, semiconductors, etc.). An ultracentrifuge apparatus was developed to generate an ultra-high acceleration field at high temperature in condensed matter. Generation of the acceleration field of over 1 million (1 x 10(6)) g at several 100s degrees C in condensed matter was achieved by using the apparatus. In this report, the realization and possibility of the ultra-high acceleration field to materials science are discussed in the light of the analytical results and the generation experiments.
