Coaxial plasm. guns are a type of plasm. source that produces plasm. which propagates radially and axially controlled by the shape of the ground electrode, which has attracted m.ch interest in several applications. In this work, a 120° opening angle of CPG nozzle is used as a plasm. gun configuration that operates at the energy of 150 J. The ionization of polyethylene insulator between the electrodes of the gun produces a cloud of hydrogen and carbon *** triple Langm.ir probe and Faraday cup are used to m.asure plasm. density and plasm. tem.erature. These m.thods are used to m.asure the on-axis and off-axis plasm. divergence of the coaxial plasm. gun. The peak values of ion densities m.asured at a distance of 25 m. on-axis from.the plasm. gun are(1.6±0.5)×10^(19)m.(-3)and(2.8±0.6)×10^(19)m.(-3)for hydrogen and carbon plasm. respectively and the peak tem.erature is 3.02±0.5 eV. The m.an propagation velocity of plasm. is calculated using the transit tim.s of plasm. at different distances from.the plasm. gun and is found to be 4.54±0.25 cm.μs and 1.81±0.18 cm.μs for hydrogen and carbon plasm. respectively. The Debye radius is obtained from.the m.asured experim.ntal data that satisfies the thin sheath approxim.tion. The shot-to-shot stability of plasm. param.ters facilitates the use of plasm. guns in laboratory experim.nts. These types of plasm. sources can be used in m.ny applications like plasm. opening switches, plasm. devices, and as plasm. sources.
