Abstract

The invention discloses a cylindrical cathode nonequilibrium magnetron plasma gas aggregation cluster source and a use method thereof. The cluster source includes a cylindrical sputtering target assembly and a condensation chamber which communicate with each other. According to the invention, the cylindrical sputtering target and an annular magnet group are used to make magnetron sputtering have alarge sputtering area and generate high yield of atoms and ions. A sputtering gas filled cylinder coaxial with the sputtering target is used to form an inert gas flow to guide sputtering products toa condensation zone, the sputtering products is further constrained by inert gas flowed out of the side wall of a buffer gas filled cylinder in the condensation zone, and so a condensation growth region of a cluster is defined in a certain space to achieve efficient and uniform growth of the cluster. A nonequilibrium magnetic field is formed by a constraint magnet of the condensation zone, and electrons are constrained to form high plasma density to obtain a high cluster iron ratio. The cylindrical cathode nonequilibrium magnetron plasma gas aggregation cluster source and the use method thereof can realize the generation of high-strength and high-ionization clusters and nanoparticle beams.
