Eighty years have passed since Langmuir's first use of the word 'plasma' for describing ionized media. On this occasion we would like to present selected recent results on application Langmuir probes diagnose plasma jet systems. To demonstrate versatility probe method give examples measurements spatial distribution parameters as well their temporal dependence in cases when system operates a pulsed regime. A part paper is devoted introducing technique, especially with regard its under...
Abstract The paper presents systematic Langmuir probe diagnostic of a dc discharge in Ar/O 2 mixture with low fraction O , burning sputtering planar magnetron. Electron density, electron temperature and plasma potential are investigated dependence upon experimental conditions like pressure, rate oxygen, incoming power, on balanced or unbalanced mode A new method determining negative‐ion density from the current‐voltage characteristic is proposed. This based comparison measured...
A method for time-resolved tunable diode laser absorption spectroscopy (LAS) has been developed. In this Letter, we describe in detail a developed electronic module that controls the time resolution of LAS system. The transistor-transistor logic signal triggering plasma pulse is used generation two signals: first one triggers fine tuning wavelength and second time-defined sampling from detector. described system enable investigation temporal evolution density temperature selected particles...
This paper will present a novel genetic-algorithm-based code (GASPED), developed for the analysis of fine features (e.g., satellite structure and line shifts) in X-ray spectra emitted by hot dense plasmas. The problem dependent modification standard genetic-algorithm concepts allows efficient decomposition concrete physical terms, such as resonance intercombination lines, dielectronic satellites, or prospective nuclear transitions. Two examples application demonstrate proposed approach. High...
Abstract The method of azoisobutyronitrile (AIBN)‐initiated bulk copolymerization styrene (S) and methacrolein (M) was employed to determine the monomer reactivity ratios r S = 0.15 M 0.55 (Q 1.50, e 0.78). Quantitative IR spectroscopy in region 4000–450 cm −1 used elucidate structure copolymers. In addition units containing aldehyde groups, copolymers may also contain cyclic hemiacetal structures formed by reaction carbonyls neighboring units. carbonyl absorption at 1722 showed that, up 30...
A modified Katsumata probe has been developed for measurement of ion velocity distribution function (IVDF) in technological non-magnetized plasmas. simple construction the consists adding a pair permanent Sm-Co magnets front probe. comparative study regarding IVDF high power impulse magnetron sputtering system operating pure argon atmosphere by means and commercially available gridded retarding field analyzer (RFA) carried out. time-resolved two different pressures whilst other plasma...
