PRODUCTION SYSTEM AND PRODUCTION METHOD OF CARBON NANOTUBE

摘要

A production system and a production method for synthesizing high-purity carbon nanotube industrially with high efficiency. The production system comprises two electrodes having foremost end parts facing each other, a power supply for applying a voltage between the electrodes, and a plurality magnets forming a magnetic field in a discharge plasma generating region, characterized in that the pole faces of the plurality magnets are arranged to face one virtual axis in the space, at least a part of one of two electrodes is located in a region surrounded by a virtual plane formed by connecting one end parts of the pole faces of the plurality of magnets in the direction of the virtual axis, a virtual plane formed by connecting the other end parts thereof, and the pole faces of the plurality magnets, and the foremost end part of the other electrode is located in the other region; and the production method using the system is provided.
