Apparatuses for trapping and accelerating neutral particles

摘要: There is disclosed a variety of apparatuses for controlling by radiation pressure the motion particle free to move with respect its environment, based on discovery that one or more beams coherent optical can overpower gravity and thermally induced reaction (photophoresis) forces small particle. The results effect include controllably heating provide black-body point light source, bombardment sample target particles, very high-energy acceleration, strong-focusing acceleration neutral particle, vacuum deposition thin films from ultrapure particles vaporized while held pressure, tensile-strength testing materials radiation-pressure circularly polarized light, measurement inertial guidance low gas pressures.
