Abstract
A magnetized plasmoid injection device including a cylindrical external electrode, a cylindrical internal electrode coaxially disposed inside the external electrode, a plasma generating gas supply unit that supplies plasma generating gas in a pulse shape between the external electrode and the internal electrode, a magnetic field generation unit that applies a magnetic field that generates magnetized plasmoid between the external electrode and the internal electrode, a power supply control unit that applies a discharge voltage between the external electrode and the internal electrode, and an impurity generation unit that contains an impurity in the magnetized plasmoid, the impurity generation unit having a cover electrode that opens to the external electrode, a thin-rod electrode that is located inside the cover electrode and is formed of an impurity, and an impurity generation power supply that applies a voltage to the cover electrode and the thin-rod electrode.
