【 摘 要 】

Glow discharge studies are produced in a atmosphere of CO2/He mixture at a pressure of 1.5 Torr . The experiment was conducted to observe the optical emission spectroscopy of the plasma, and determined the electron temperature and ion density by the use of a double Langmuir probe. The electron temperature of the mixture was found in the range of 4.54 to 5.37 eV, and the ion density values between 2.15 and 12.00 × 109particles/cm3. The principal species observed were: CO2+CO+, CO, C2, O2+O∗, and He∗.
