S-, P- and R-striations as attractors for electron phase trajectories in spatially periodic resonance fields

A new point of view on the appearance of S-, P- and R-striations in a positive column of inert gases is proposed, based on a dynamic analysis of the resonance properties of electron phase trajectories in spatially periodic fields. The positive column may be considered as a resonator containing a set of resonant modes. Like a tuning fork, being disturbed, it responds with one of the modes, in particular with of S-, P-, or R-modes or striations, depending on the discharge conditions. The dynamic approach eliminates the difficulties of the kinetic theory associated with the long length of the solution of Boltzmann equation, which is much greater than the length of the positive column.

Analysis of the system of current stabilization of the radiation power of glow-discharge lasers

The article analyzes the transfer function of the discharge gaps of glow discharge lasers. The transfer function in this case shows how a change in the discharge current leads to a change in the concentration of electrons in the positive column, which are an energy source for the excitation of laser levels. Based on the analysis, the characteristic time constants of the transfer function were calculated for the main types of glow discharge lasers.

Distribution of the charged particles of a gas-discharge laser plasma in a transverse magnetic field. II. Experimental study

The paper presents an experimental verification of the adequacy of a physical and mathematical model describing the influence of an external transverse magnetic field on the distribution of the charged particles in a positive column of a gas discharge. A gas-discharge laser located in a transverse magnetic field was used to conduct the study. The vacuum installation allows pumping out the system and feeding the gas mixture into it under a certain pressure. The data obtained during the experiments differ from the calculated ones by no more than 4–5 %.
