S"imple Waves in the Chew, Goldberger, and scv/56-37-3-25/62
Low Approximation
interesting case in which hydrostatic pressure is considerably
lower than magnetic pressure. In the ranges with expansion the
density gradient decreases, and in the ranges of compression it
insreases. In the ranges with expansion (f'>0) and in the
self-simulating waves (f - 0) density decreases. In the ranges
of the compression (fl---O) density increases until a certain
expression written doym by the authors becomes negative.
As soon as this expression equals zero, a compression shock
wave is formed. In a fast magnetic sound waveg the quantities
po 9 pj. 9 H 9 p.L/pjj change in the same way as in the magnetic
sound wave. The authors then investigate a slow magnetic sound
wave. There are two possibilities: (1) In the normal case,
density changes in the same way as in a fast magnetic sound
wave. Shock waves are formed especially in the ranges of
compression, and the self-simulating waves are expansion waves.

(2) In the abnormal case the density gradient decreases in the
ranges of compression and increases in the ranges of thinning
In the ranges of expansion a shook wave is formed. In contrast
to magnetohydrodynamics with scalar pressure, expansion shook
waves may form in this case. The authors thank A.I. Akhiyezer

TEXT: The author studies the energy loss of a charged particle and of a
cluster of particles exhibiting the shape of a disk with uniformly
distributed charge density, on its moving at constant velocity along the
axis of a relativistic electron-ion beam. The problem is solved in hydro-
dynamic approximation. The author proceeds from the linearized
differential equation system (1) which describes the interaction of a
charged particle or of a charged disk with the beam. The following cases
are studiedt 1) the passage of a charged particle moving along the z-axis
at the constant velocity u', through a relativistic electron-ion beam
enclosed in a cylindrical waveguide; 2) the same for a waveguide with a
radius tending to infinity; 3) the passage of a charged infinitely thin

disk with a radius equaling the diameter of the waveguide, at a constant
velocity along the z-axis; 4) the same for a disk with the finite thick-
ness h. Condition (24) is given for the appearance of Cherenkov radiation,
moreover an expression is obtained for the intensity of Cherenkov
radiation, and the frequency spectrum is examined. Maximum Cherenkov
radiation appears at a given frequency if the waveguide radius obeys to
formula (16). The author finally thanks Professor A. 1. Akhiyezer'and

TITLEs Production of Hyd
romagnetic and Magnetic Cherenkov Waves in
a Dilute Anisotropic Plasma
PERIODICALt Zhurnal tekhnicheskoy fiziki, 1960, Vol~ 30, No~ 10,
Pp. 1178-1185
TEXTs The authors determined formulas for the power of Cherenkov
radiation from mobile sources. A charged filament and several circuits
moving with a high velocity served for the production of waves, Equations
by Chew, Goldberger, and Low (Ref. 1) were used to derive the above-
mentioned formulas. These equations, which are similar to the set of
equations of magnetohydrodynamics, are, however, only valid for a plasma
moving across the magnetic field. In the present work, they were used to
study the production of waves in an anisotropic plasma by means of
circuits and a charged filament moving both across and along the magnetic
field. It is noted that the results obtained possibly do not hold for the
case in which the circuits in the plasma move in the direction of the

magnetic field. The greatest difference between an isotropic and an
anisotropic plasma is that hydromagnetic waves are strongly excited in
the latter plasma. This phenomenon is caused by the appearance of aniso-
tropic Alfvgn waves in the medium under consideration. A similar problem
was studied by A. I. Morozov (Ref. 4) for an isotropic plasma the circuit
of which moves along the external magnetic field, The data obtained by
the authors are in qualitative agreement with Morozov's results~ The
authors thank N. M. Poliyevktov-Nikoladze, Ya. B. Feynber , A,G. Sitenko,
and D. G. Lominadze for discussions. There are 1 figure and 4 Soviet
