The dc glow discharge can be subdivided into several zones between the cathode and the anode; only three zones (the cathode fall, negative glow, positive column) are the most important regions. The negative glow, the most luminous region due to many excitation and ionization collisions, was probed by a double of tungsten cylindrical Langmuir Cited by: 3. Abstract. Electron detachment from negative ions may considerably influence the spatial charge distribution and the temporal development of discharges, as all unstable negative ions generated become potential electron by: 3. In this paper, emission spectra of both positive column (PC) and negative glow (NG) regions of the dc glow discharge have been measured at different pressures and currents.

  A dc plane glow discharge in a nitrogen-hydrogen (N2-H2) gas mixture has been operated at discharge currents of 10 and 20 mA. The electron energy distribution function (EEDF) at different hydrogen concentrations is measured. A Maxwellian EEDF is found in the positive column region, while in both cathode fall and negative glow regions, a non-Maxwellian one is Cited by: 2.   William Boyd Montgomery has written: 'Electron and positive ion analyses in the negative regions of the glow discharge' Asked in Grammar What are the examples of denotations and connotations? The ion and electron populations of a glow discharge that uses an electrolytic solution as the cathode (an electrolyte-cathode discharge or ELCAD) were investigated.

The process occurs in a rectangular duct with convective cooling [23,24] and is described by the 2D model of current contraction. If the contraction develops in a tube, [2,5,8] a cylindrical model with axial symmetry is more accurate. For experiments [9,16]. A glow discharge is self-sustaining because positive ions that are accelerated to the cathode impact on it, producing more electrons in a process called secondary emission. This is why the voltage at which a discharge goes out is lower than the voltage at which it initiates.
