The non-uniform argon d. glow d.s.harge plas.a s.s.em has.been cons.ructed.in a very s.ecial d.s.gn to inves.igate the effects.of variable tube rad.us.on plas.a parameters. By us.ng is.lated.computer controlled.three couples.of a d.uble probe （TCd.） s.s.em, the electron temperature, electron d.ns.ty, the red.ced.electric field. and.electron d.ift velocity are meas.red.at low and.intermed.ate pres.ures. It is.s.own that the electron temperature and.red.ced.electric field.（d.ns.ty） d.creas.s.（increas.s. as.the rad.us.d.creas.s. at low d.s.harge current and.pres.ures.
