    • The present invention discloses a microwave plasma applicator. The micro plasma applicator includes: a vertical cylinder type housing in which a microwave waveguide horizontally extended in the center is engaged; a gas inlet pipe connected to an upper end of the housing for inhaling gas into a cavity of the housing; an outlet formed in a lower end of the housing for discharging plasma to the outside; a plasma tube arranged in the cavity of the housing, of which the upper end is connected to the gas inlet pipe and the lower end is connected to the outlet; a solenoid copper pipe for maintaining a gap in which microwave come into the microwave waveguide pass through, wound up to the outer surface of the plasma tube having coolant inside; a first electrode connected to an upper end of the solenoid copper pipe; and a second electrode connected to a lower end of the solenoid copper pipe. Therefore, damage to a plasma tube is prevented by forming a magnetic field in the plasma tube using a solenoid coil.
    • 本发明公开了一种微波等离子体涂敷器。 微型等离子体施加器包括:垂直圆筒型壳体,其中在中心水平延伸的微波波导接合; 气体入口管,其连接到所述壳体的上端,用于将气体吸入所述壳体的空腔中; 出口形成在壳体的下端,用于将等离子体排放到外部; 布置在壳体的空腔中的等离子体管,其上端连接到气体入口管,下端连接到出口; 用于保持微波进入微波波导的间隙的螺线管铜管通过,卷绕到具有冷却剂的等离子体管的外表面; 连接到电磁铜管的上端的第一电极; 以及连接到电磁铜管的下端的第二电极。 因此,通过使用电磁线圈在等离子体管中形成磁场来防止等离子体管的损坏。
