METHOD FOR DETERMINING CONCENTRATION OF ELECTRIC-NEGATIVE ADMIXTURES IN NON ELECTRIC-NEGATIVE GASES

FIELD: measuring technologies. ^ SUBSTANCE: method includes ionizing controlled gas by beta or alpha particles with periodical collection of ionization charges from gas volume. Using charge-sensitive amplifier, only charge of gathered electrons is registered from each alpha and beta particle, or in even time intervals, of adjustable length. To abolish ambiguousness of measurements in noble gases, ultra-pure molecular gas is added to them, effectively thermalizing electrons, drifting in gas under effect from electric collecting field. ^ EFFECT: broader functional capabilities, higher precision. ^ 2 cl, 3 dwg
