ON THE FEATURES OF ELECTRIC FIELDS CHARACTERIZATION IN DC ATMOSPHERIC PRESSURE HELIUM DISCHARGES USING POLARIZEDSTARK SPECTROSCOPY

The effect of fluctuations in the discharge current on the Starks broadening components of helium and hydrogen lines in the cathode fall layer of the potential is investigated. The oscillations are analyzed with the use of elements of chaos theory.56-5

APPLICATION OF DC ATMOSPHERIC PRESSURE PLASMA JETS FOR INACTIVATION OF MICROORGANISMS CONSORTIUMS

Experimental results for inactivation of microorganism test strains of S. aureus, E. coli, P. aeruginosa separately and in such consortium by air plasma jet are presented. For monocultures of S. aureus, E. coli, P. aeruginosa the characteristic D-times are practically the same and are around 1.5 min, while for the consortium these is 3 min.57-5

Small-Size Resonant Photoacoustic Cell of Inclined Geometry for Gas Detection

A photoacoustic cell intended for laser detection of trace gases is represented. The cell is adapted so as to enhance the gas-detection performance and, simultaneously, to reduce the cell size. The cell design provides an efficient cancellation of the window background (a parasite response due to absorption of laser beam in the cell windows) and acoustic isolation from the environment for an acoustic resonance of the cell. The useful photoacoustic response from a detected gas, window background and noise are analyzed in demonstration experiments as functions of the modulation frequency for a prototype cell with the internal volume ~ 0.5 cm^3. The minimal detectable absorption for the prototype is estimated to be ~ 1.2 10^{-8} cm^{-1} W Hz^{-1/2}.Comment: 11 pages, 5 figure
