| Abstract In this work, we have successfully designed and constructed argon D.C glow discharge plasma. A planer D.C diode system consisted of two aluminum electrodes which were designed and constructed to study Paschen's curves at two different interelectrode distances (3cm and 4.5cm). The breakdown voltage (Vb) was experimentally measured as a function of the pressure product of inter-electrode distance (Pd) for argon discharges gas. The behaviour of breakdown voltages as a function of (pd) coincide with Paschen’s law at the two different interelectrode distances. The minimum breakdown voltages were (Vb) min =(232, 244)volt for d=(3, 4.5)cm respectively and the minimum pressure product by the inter-electrode distance namely pdmin=. (1.1,1.5) mbar.cm at the two above distances. | ||
