Summary:The plasma stream presented by our coaxial plasma gun includes various impurity components of which copper and carbon are very serious. Emission lines from these impurities are measured by a 3. 4M Fastie-Ebert type polychrometor. In order to reduce copper ions, a longitudinal magnetic field is applied along, the passage of the plasma stream. For example, relative intensity of CuII 2247A to HeII 4686A is redu ced to 1/30 after passing through a magnetic field of 1000 gauss. Also, this relative intensity varies with operation conditions of the gun.
