“…During the clusters explosion, the electric current is conducted by negative ions, but not free electrons. The magnitude of the pulse current during every separate cluster explosion corresponds to experimental data, found by (Mesyats, 2000), (Mesyats, 1993) and (Mesyats, 1995).…”

“…Then the current density, caused by the negative ions discharge from the cathode spots is ~ 4.6•10 12 A/m 2 for the titanium cathode spot, ~ 1.37•10 13 A/m 2 for iron and ~ 1.3•10 13 A/m 2 for copper. Exactly the same current densities were experimentally found during the ecton explosion (cluster) (Mesyats, 2000), (Mesyats, 1993) and (Mesyats, 1995).…”

“…The explosive processes investigations in the cathode flames were carried out by Mesyats with colleagues and it was found that micro explosions can be generated inside the cathode spots on separated low-sized particles, called ectons, (Mesyats, 2000), (Mesyats, 1993), (Mesyats, 1995).…”

The paper describes a new phenomenon of the generation of the double electrical layer above the cathode spot surface. The neutralization of this layer leads to the reverse current of free electrons, generated due to negative ions ionization. The negatively charged flame of the cathode spot periodically ignites and attenuates, so the duration of the cathode spot existence is defined by this oscillating process. The reverse motion of the cathode spot in the longitudinal magnetic field takes place owing to the generation of the reverse high-power neutralization current of the double electrical layer by the electrons appearing during the negative ions ionization in the cathode flame.

“…As for the discharge between copper electrodes, the intensity of this group of spectral lines decreased with decreasing nitrogen pressure from 202 to 101 kPa. An essential role in introducing the material of electrodes, both metal and semiconductor, into the interelectrode gap is played by the ectonic mechanism of their sputtering in a strong electric field of a nanosecond discharge [16].…”

The electrical and optical characteristics of the overstressed nanosecond discharge in nitrogen at a pressure of 202 kPa, which was ignited between electrodes from chalcopyrite (CuInSe2 ), are presented. Upon sputtering of chalcopyrite electrodes, CuInSe2 compound vapors have been introduced into the discharge plasma. Chalcopyrite molecules were partially destroyed in the plasma and partially deposited in the form of thin films on a quartz substrate, which was placed near the system of discharge electrodes. The main decomposition products of a chalcopyrite molecule in an overstressed nanosecond discharge were found, which were in excited and ionized states and which, in the plasma emission spectra, were mainly represented by atoms and singly charged copper and indium ions. The spectral lines of copper and indium are proposed, which can be used to control the deposition of thin films of chalcopyrite in real time. On quartz substrates, gas-discharge method was used to synthesize thin films based on the CuInSe2 compound, which effectively absorbed light in a wide spectral range (200-800 nm), which opens up prospects for their use in photovoltaic devices.

“…Наносекундний і субнаносекундний сильнострумові розряді в повітрі атмосферного тиску між металевими електродами є джерелом УФ випромінювання на переходах атомів та іонів матеріалу електродів (Мідь, Цинк, Залізо, Вольфрам тощо) у вузькому спектральному інтервалі 200-300 нм [1][2][3]. Внесення парів матеріалу електродів в плазму в сильному електричному полі відбувається за рахунок мікровибухів неоднорідностей на поверхні металевих електродів, що призводило до внесення пари матеріалу електродів в плазму і утворенню ектонів [4]. На відміну від УФ-ВУФ ламп з накачуванням тліючим [5] або бар'єрним розрядом [6], «точкові» УФлампи можуть мати дуже малі об'єми плазми на рівні 1-5 мм 3 В плазмі наносекундного розряду у Гелії високого тиску (р = 1-5 Атм) між нержавіючими електродами при перенапруженні в 100-300 % теж були виявлені в спектрах випромінювання спектральні лінії атомів Заліза (у діапазонах довжин хвиль 360-400 нм; 700-730 нм) [10].…”

atoms and iron and copper ions in the spectral range 200-300 nm. The peak value of the electric power of the discharge is ~ 4 MW, and the energy contribution to the plasma per pulse was ~ 0.1 J. The developed point source of UV radiation based on the discharge between the copper and stainless electrode is promising for applications in medicine and sanitation. It has been established that under the assistantance by UVradiation the developed "point" source in the nanostructures of iron oxides, enlightenment bands appear in the visible region of the spectrum. Conclusion: Experiments revealed the suitability of this discharge for use in a selective "point" UV lamp on iron and copper vapor and deposition of nanostructured films based on iron oxides while assisting the process of deposition by UV radiation.
