| 英文摘要 | An arc discharge with channel diameters of 3 mm and 6 mm and lengths between 30 mm and 60 mm was experimentally investigated for its potential to function as plasma window, i.e., interface vacuum regions of different pressures. Electron temperature of the plasma channel measured spectroscopically varied in the range of 7000 K to 15 000 K, increasing with discharge current while decreasing with gas flow rate. That plasma window had a slightly positive I-V characteristics over the whole range of investigated current 30 A-70 A. Measurements of pressure separation capability, which were determined by input current, gas flow rate, discharge channel diameter, and length, were well explained by viscosity effect and "thermal-block" effect. The experimental results of global parameters including temperature, gas flow rate, and voltage had a good agreement with the simulation results calculated by an axis-symmetry Fluent-based magneto-hydrodynamic model.
