Abstract

This work proposes a novel method of Thomson microwave scattering for electron number density measurements of miniature plasmas at pressures <10 Torr. This method is applied to determine electron number density in a positive column of glow discharge initiated at 5 Torr in air with a plasma column diameter of 3.4 mm. The Thomson Microwave Scattering (TMS) system measured the electron number density to be 3.36∙1010 cm-3. The result obtained using the TMS system was validated against the measurements made using the well-known technique of microwave quarter-wave hairpin resonator. Measurements with the hairpin resonator yielded an electron number density of 2.07∙1010 cm-3 providing adequate agreement with the TMS system.
