Experimental verification of Boltzmann equilibrium for negative ions in weakly collisional electronegative plasmas
Weakly collisional Ar- O2 electronegative plasmas are investigated in a dc multidipole chamber. An electronegative core and an electropositive halo are observed. The density ratio of negative ions to electrons (α) in the nondrifting bulk is found to be 0.43. The profile of α is found using both the...
