Abstract

The characteristics of the magnetic confined discharges under high gas pressure (> 10⁴ Pa) are investigated, e.g. electron motion equation under electromagnetic fields, electron transport coefficients, the influences of magnetic field and gas pressure on the discharge behavior. The electron mobility (mu) and conductivity (sigma) in the discharge space may change under the influences of magnetic field. Other side, as the increase of gas pressure, the impact frequency between electron and gas molecule will increase, this will increase the electron mobility (mu) and conductivity (sigma) . In the high gas pressure the stable discharge can be obtained only with the high magnetic flux density. This conclusions are proved from the experiments of TEA---CO₂ laser and excimer laser.
