Characteristics of an argon glow-discharge in presence of small O(2) and H(2) admixtures
Glow discharges are widely used in modern technology. Nevertheless the basic physical processes in these discharges are not yet fully understood. Characteristic parameters of comparable experiments often show a strong deviation. The present work considers the influence of oxygen and hydrogen admixtures on the voltage-current characteristics and on the thickness of the sheath in a dc argon glow-discharge with titanium cathode. The cathode fall length was measured with a Langmuir probe and compared with values obtained from the axial distribution of emission light from neutral and single ionised argon atoms.
