Electrical properties of the µs pulsed glow discharge in a Grimm-type source: comparison of dc and rf modes

Abstract: The electrical properties, in particular the U-I characteristics, current and voltage signal shapes within the pulse, are important parameters for the understanding of the processes taking place in the pulsed glow discharge (PGD). The electrical properties are also closely related to the analytical performance of the PGD such as sputtering rates, crater shapes and emission yields. Moreover, the dependence of the U-I plots on the density of the discharge gas can be used to estimate the gas temperature. This res… Show more

“…To simplify the optimization work, it was assumed that p and f have a smaller effect on the shape of the sputtered crater as compared with the other parameters. 25,27,28 However, in the case of rf discharge, it is hard to measure the current reliably. Therefore, in the present work the pressure is measured instead.…”

“…Нагрев нейтрального газа. Большой цикл работ (см., например, [2][3][4][5][6]) посвящен формированию униполярного импульсного разряда в аргоне и азоте. При этом в качестве одного из ключевых факторов, оказывающих влияние на формирование параметров импульсного разряда, рассматривается изменение температуры нейтрального газа в разрядном промежутке под воздействием энергии, вкладываемой в плазму импульсного разряда.…”

“…Как показывают результаты работ [1][2][3][4][5][6][7][8][9], импульсные разряды обладают рядом специфических особенностей, которые могут быть полезны в разнообразных приложениях. Например, в работе [3] микросекундный импульсный тлеющий разряд применялся к источнику плазмы типа Грима, который используется для ионизации анализируемых веществ в масс-спектрометрии.…”
