In this work, we carried out an experimental study of thedustyplasma by taking the dust material Fe3O4 with radius of the any grain0.1μm - 0.5μm. In experiment we use air in the vacuum chambersystem under different low pressure (0.1-1) Torr. The resultsillustrated that the present of dust particles in the air plasma did noteffect on Paschen minimum which is 0.5 without dust and with Fe3O4dusty grains.The effect of Fe3O4 dust particles on plasma parameters can benotice in direct current system in glow discharge region. The plasmaparameters which were studied in this work represent plasmapotential, floating potential,electron saturation current, temperatureof the electron, the density of the (electron, ion), and Debye length.The measurements of parameters are taken by four cylindrical probeswhich diagnosed at distance 4cm from the diameter of the cathode inPaschen minimum at pressure 0.5 Torr. The diameter profiles ofplasma parameters in the present of dust are non- uniform. Plasmapotential and the floating potential of probe becomes more negativelywhen the dust immersed into plasma region. The electron densityincreases in the present of dust particle which lead to decrease theelectron temperature and Debye length. The behavior of thoseparameters shows the discharge current and discharge voltageincreases without dust while the discharge current and voltagedecreases when Fe3O4 dust particles embedded.
