Abstract
Gases (CO Xe and H) are freezed into a column, 0.4mm in diameter and about 0.7mm long, which is moved in a vacuum chamber by a pipe and remains hanging down. The column is thined at the root as a result of gradual evaporation and is cut by a low power laser pulse or by a edge driven mechanically. The light signal scattered from the falling column triggers a Q-switched laser (100 MW). The laser light pulse is focused on a particle isolated at the center of a vacuum chamber to produce high-temperature and high-density plasma. Such plasma will contribute to the fundamental research of plasma physics.
