Engineering Physics Annotation << Back BASIC STAGES IN FUNDAMENTAL PHYSICS OF COLLISIONLESS PLASMA A.A. RUKHADZE The short review of developing of fundamental plasma physics is given. Enumerate under the title of this paper physicists set up the basic stages in this region of science. 1. I. Langmuir fi rst experimentally investigated the properties of plasma, found the main characteristics of the plasma conditions and determined implementation of the plasma state. 2. L.D. Landau realized the reason for the inapplicability of the fi rst gas approximation for describing the plasma, but ignored the self-consistent fi eld and has not reached the goal. 3. A.A. Vlasov showed the important role of the self-consistent fi eld and fi rst received the correct equation describing the plasma, as well as theoretically grounded experiments I. Langmuir observation of plasma waves and their dispersion. 4. N.N. Bogolubov developed a general method for deriving the dynamic equations for the plasma and showed that in the fi rst approximation in the parameter Landau rightly Vlasov equation, and three times the approach leads to Landau amendment to the Vlasov equation. 5. G.V. Gordeev fi rst showed that the sound vibration branch different from the sound in gases, ion- sound vibration in a plasma is isothermal and exists only in nonisothermal plasma in there. 6. B.B. Kadomtsev and V.P. Silin showed that exist in the plasma undamped fashion ion-acoustic oscillations(Vlasov’s modes), and for the fi rst time developed a theory of plasma turbulence on the undraped Vlasov modes. Key words: Lengmuir frequency, Boltzmann’s equation, Valov’s equation, Self consistent fi eld, Landau collision integral, collisionless Vlasov damping, isothermal ion-acoustic wave.
