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
