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.
