The characteristics of the non-uniform glow discharge with the effect of the hollow cathode (EHC), on which the chosen regimes of nitriding the surface of titanium alloy VT6 are considered. Experimental results of the influence of inhomogeneous plasma in a pulsed regime of processing on the structure and microhardness of the treated surface are resulted.

The surface topography developed on copper-based and ferrous alloys after being sputtered in a glow discharge lamp and in an ion microprobe was studied by means of a scanning electron microscope and an ion microprobe mass analyser. The observed surface topography, though obtained under completely different conditions, was found to be similar to that predicted by the theory of Stewart and Thompson.

The Lamb dip of the CO(2) saturation signal in an extracavity low-pressure CO(2)-N(2) rf glow discharge is detected optogalvanically and used to stabilize the frequency of a CO(2) laser. The frequency stability is estimated to be better than 100 kHz.

Two–dimensional capacitively coupled radio frequency discharge in methane is simulated by PIC-MCC method. The results were obtained in pressure range 50-300 mTorr and voltage range 40-180 V for discharge frequency 13.56 MHz. The electron energy and electron– methane reaction rates spatial distributions show existence of two regimes of discharge glow: a) with active sheaths, when electrons are h...

The most important features of microcrystalline silicon (Fc-Si:H) and microcrystalline silicon based p-i-n solar cells (specially those deposited by VHF-Glow Discharge) are reviewed. Since such material has been recognized to be a photovoltaically active material, stabilized cell efficiencies have steadily risen and have now reached 12% in the so called “micromorph” (microcrystalline/amorphous)...

It is shown that inhomogeneous heating of the dust grain by ion flow in a glow discharge results in a photophoresislike force. According to our estimations, this radiometric force can be comparably-valued with the ion-drag force under the conditions of microgravity dusty plasma experiments.

Uranium foils were attached to the cathode of a glow discharge apparatus. A plasma of either hydrogen or deuterium ions was used to bombard the uranium. The rates of alpha, beta, and gamma radiation emissions were significantly greater for the bombarded uranium than for the original material.

The density of the metastable He atoms in the positive column of a glow discharge is determined using two techniques involving a Fourier Transform spectrometer. The techniques are the traditional self-absorption method and the newly reported Doppler shift technique. The two results agree well within the experimental errors.

2014 The pure-hydrogen discharges in surface-plasma sources with a semiplanotron electrode configuration are described. In short pulse (10-3 s) mode the extracted Hemission density was up to 1.1 A/cm2 at cathode discharge current density 60 A/cm2. The multi-slit short pulse extraction delivered the Houtput with current of up to 1 A. In the long pulse (0.6 s) mode the Hyield was 0.15 A at discha...
