INFLUENCE OF THE METASTABLE ATOMS LIFETIME ON THE RUNNING STRIATION EXCITATION

Abstract
It is known that in the noble gas discharges inside a region of the running striation excitation there can be a relatively small region of currents and pressures in which there are no striation /1/. The boundaries of this region depend on the gas composition and discharge tube dimensions /2,3/. The investigation of a non-striation region is of great practical interest because the operating ranges of pressures and currents in helium-neon lasers usually overlap it /3/. In this work the presence of a non-striation region is explained by the finite lifetime of the metastable atoms.
