The author study a nonself-sustained gas discharge in N2-CO2 mixtures at atmospheric pressure. An electron beam was used as the external ionizer. In the experiment stable burning of such a discharge in a steady-state regime was realized. This analysis shows promise in the use of such discharges a combined pumping of CO2 lasers.

An examination is made of the statement and numerical solution of the problem of the development of ionization instability in a low-temperature magnetized plasma. Basic attention is devoted to the dynamics of the development of instability and a qualitative analysis of the phenomenon. The effectiveness of the physical model used as the basis of the examination is shown. As a result of the numerical calculations, the association between the average parameters of the plasma at process stages close to turbulence is refined., Edited trans. of mono.

A nuclear reactor has already been employed as a source of ionization of gas in a considerable volume (approximately 750 cc) at a pressure close to atmospheric in experiments on immediate excitation of generation in a Hg + He3 mixture. This paper reports about experiments on combined excitation of a CO2 laser conducted on the same reactor (flow density of thermal neutrons in the central channel D approximately 5 x 10 to the 16th power neutrons/sq cm-sec, pulse length about 1 msec)., Trans. of Zhurnal Experimentalnoi i Teoreticheskoi Fiziki.

The authors discuss the possibility of using certain conduction and induction MHD generators schemes for converting the energy of pulsed thermonuclear reactors (PTR), in which energy release occurs in a blanket which absorbs the basic fraction of hard radiation. The physical limitations on the achievable efficiency of conversion and the plasma parameters obtainable in the reactor (pressure about 1 kb, temperature about 2-3 eV), and the selection of working substance are explained. Sample parameters for a Faraday supersonic plasma MHD generator having solid electrodes (about 0.4 efficiency) and an induction piston MHD-generator (about 0.7 efficiency) which generate d.c. current and voltage are presented.
