| Abstract: | A magnetic DC plasma torch is introduced. The magnetic field distributions of solenoid coils have been calculated. The effects of magnetic field on the discharge characteristics and voltage current curve of the torch are investigated. Argon and hydrogen plasma parameters, such as electron temperature and density, are measured with Langmuir probes at 80mm from the nozzle. It shows that magnetic DC plasma torch can work in a wide range of operation parameters, which seems to be applicable to large area and high rate film deposition. |
