“…Одним из методов повышения устойчивости газоразрядных детекторов к пробою является нанесение на электроды резистивных покрытий [5][6][7][8][9][10][11], которые препятствуют развитию дуговой стадии пробоя путем локального снижения напряжения в области газового усиления. В качестве таких покрытий различными научными группами исследованы углеродные резистивные пленки [5,7,10], DLC-покрытия [6][7][8][9]11], покрытия CuO и CrO [12].…”

The relationship between sp^2/sp^3 hybridizations ratio of atomic bonds in diamond-like carbon (DLC) and its electrical resistivity for coatings with a thickness in the range 22-70 nm prepared by vacuum arc deposition on silicon substrate of the SHB-8 brand has been established. It is established, that an increase in the coating thickness from 22 to 70 nm is accompanied by a decrease in the specific transverse electrical resistance of samples from 17 to 2 GOhm·m. This effect is explained by an increase in the proportion of carbon atoms with sp^2 hybridization of electronic orbitals from 86 to 91%, which leads to the appearance of an additional number of π-bonds. A mathematical model, describing the spatial distribution of current when measuring transverse I-V characteristic, has been developed. The results obtained will be useful in creating resistive layers on the electrodes of gas-discharge detectors of charged particle to limit the amount of current in the event of rare spark discharges inside them caused by the registration of random highly ionizing particles.

“…One of the methods of increasing the resistance of gasdischarge detectors to breakdown is the application of resistive coatings [5][6][7][8][9][10][11] to the electrodes, which prevent the development of the arc stage of breakdown by locally reducing the voltage in the gas gain region. As such coatings, various scientific groups have studied carbon resistive films [5,7,10], DLC-coatings [6][7][8][9]11], coatings CuO and CrO [12].…”
