ABSTRACT: A short review of high frequency collisionless methods for heating plasma to
thermonuclear temperatures is given and a comparison with ohmic heating is made; an ex-'
haustive bibliography of theoretical and experimental works is included. The methods
reviewed in detail are: 1) Cherenkov heating of ions, 2) Cherenkov heating of elec-
trons by magnetoacoustic waves, 3) cyclotron absorption of magnetoacoustic waves, 4)
ion cyclotron resonance and Alfven's wave absorption. Heating rates for these proces-1
ses are given and compared with the containment times needed to achieve sufficiently
high temperature of the ions (50 kev) for the thermonuclear reactions to occur. it is!
shown that Cherenkov and cyclotron heating with weak fields is the same as ohmic heat-
ing if the distribution function for equilibrium is reached through collisions. Fur-

by a beam of oscillators (i. e., a beam consisting of particles with an identical gyro-,
iradius) in a longitudinal magnetic field is investigated. The plasma is assumed to
!have Maxwellian distribution while the beam has a similar distribution for its longi-
tudinal velocity. The transverse velocity of the beam is taken to be a delta function.
iThe dispersion relation for the longitudinal wave is used to investigate the damping co~i_
;efficients of various waves. A detailed analysis of the "hot" beam and "cold" bean is
Made. The criteria specifying the point at wbich the beam satisfies the above desig-

problem under consideration Is limited to short wavelength excitations (much shorter
than the Larmor, radius). Growth rate and frequency of the wave am taken to be much
greater than the gyrofrequency of the Ions. This permits one to view the Ions as
Ing effectively in a direction perpendicular to the external field. The contribution
of the beam to the dielectric tensor of the plasm, is described and the sms of each
of the elements Is rewritten In terms of suitable integrals. This leads to a simpli-
fi*d expression for the elesients In terms of wavelengths, which In turn yields the dis-
persion relations. The latter we characterized by the presence of a resonance factor.

ABSTRACT: The stability of two identical plasma streams moving along a static magneti
field in opposite directions is investigated in the region intersected by the streams.
It is assumed that the streams are characterized by an electron temperature higher tha
that of the ions. The dispersion relation for the magnetosonic waves is written and
immediately simplified by the elimination of small anti-hermitian factors, using, in
effect, hydrodynamic approximation. The equations hold for low-frequency oscillations
with the phase velocity of the waves being much smaller than the thermal electron velo
city but greater than the thermal ion velocity. When beam velocity exceeds the Alfven
velocity, transverse Alfven waves are excited; however, when acoustic velocity exceeds
beam velocity, acoustic waves are generated. An expression relating these velocities
is derived giving the region in which beam instability also develops. It to also show

interpenetra-ting plasma streams moving in opposite directions parallel to a magne-
tic field is discussed theoretically. The temperatures of the two streams are as-
sumed to be the same, and the electron temperature is assumed greatly to exceed the

quency is low compared with the ion Larmor frequency, the wavelength is consider-
ably greater than the electron and ion Lamor radii, and the component of the phase
velocity parallel to the magnetic field is low compared with the electron and high
compared with the ion thermal velocity. The antihermitian part of the dielectric
tensor, describing Cerenkov absorption and radiation, is neglected. The roots of

ABSTRACT: The authors discuss the stability of two plasma streamsof equal density
band temperatures moving, through each other in opposite directions parallel to an
Vxternal magnetic field. The following cases are treated separately: 1) low-fre-
quency longitudinal oscillations when the magnetic pressure is large compared with
the kinetic, the electron thermal velocity is large compared with the stream velo-
C~ty, and the ion thermal velocity Is negligible; 2) high-frequency longitudinal
oscillations when the thermal velocities of both the electrons and ions cre small
compared with the stream velocity; and 3) oFicillations that occur when the ion tem-,
pe rature is high. In each case the requisite dispersion equation is either quoted
from earlier work (A.B.Kitsenko and K.N.Stepanov, ZhTF 32,303,1962) or written

without derivation or reference. The behavior of the dispersion equation is illus-'
trated graphically in each case, the stability conditions are derived, and equa-
tions are derived for the growth corLstants (logarithmic increments) near the sta-
bility boundaries. The instability found in case 1) when the stream velocity Is
large compared with the velocity of sound could be employed to heat the ton compo-
nent of a plasma, the electron component of which had been previously raised to a
high temperature. The growth constant of the oscillations in case 3) is small, but if
these oscillations may still be Important in interacting plasma streams because
the ions carry the major portion of the stream energy. "In conclusion, the authors
express their gratitude to A.I.Akhilezer for discussing the.results and for valu-
able advice." Orig.art.has% 21 formulas and 3 figures.

ABSTRACT: The authors discuss the excitation in a plasma of oscillatIM3 propagat-~
ing nearly perpendicularly to an external magnetic field by a stream of ions, all
of which have the same Larmor radius. These ions are the "oscillators" of the title.

of the present problem, and the roots of the dispersion equation are discussed for
ordinary, extraordinary and longitudinal waves. The dispersina equation has root3
not only at frequencies near harmonics of the electron Larmor frequency and the hy-
brid frequency, but also at a frequency close to the ratio of the ion beam velocity
to the wavelength. The logarithmic increment of the longitudinal waves is much grea-
ter than that of the tranbverse waves; it is proportional to (n/n)2/*5, where n'aid
n are the particle densities of the ion beam and the plasma, respectively. If the
plasma contains no ions except those of the beam, It is unstable under all condi-
tions. Instability of this type may be expected to arise In high density adiabatic
magnetic mirror systems in which the ion velocity distr:.bution -is highly anisotro-
pic. "In conclusion, the authors express their gratitude to VLEL&Ighlia for valuable :1

A13STRACT: The authors discuss the excitation of low frequency longitudinal oscil-
lations of a plasma in the presence of an external magnetic field by a stream of
charged particles having a delta-function distribution of velocity components per-
pendicular to the magnetic field and a MaxwellIan distribution of the velocity can-
i ponent parallel to the field. The dispersion equation Is written without derivation
or reference, and its solutions are discussed at considerable length. Long wave-
length oscillations occur with phase velocities much greater than the thermal velo_,___
cities of the plasma particles and, in the case of a highly anInothermal plasma, I
with phase velocity Intermediate between the Ion and electron thermal velocities.

ABSTRACT: The authors calculate the focusing effect In a traveling wave linear
-accelerator of a reflected wave propagating in the opposite direction to the
electron motion. The reflected wave Is found to improve the focus both with re-
spect to phase and with respect to radial motion. The improvement in phase stabil-
Ity is shown,,to be negligible in the relativistic case and to be significant in the
nonrelativistic case only when the equilibrium phase is close to g/2. The radial
focusing is improved at all energies. The radial focusing effect of the backward
traveling wave Is equivalent to that of a uniform longitudinal magnett6 field of
which the strength in of the order of the wave amplitude. The radial focusing
effect was verified experimentally by directing a divergent beam (divergence angle

region does not greatly affect the propagation of surface waves with frequencies

Lnrmor frequency, however, the wave reeonates with the 1,nngmuir frequency at some
point within the transition layor and the wave amplitude becomes Inrge. In this

low. The dielectric tensor in the presence of space dispersion is quoted from

to calculate the wave amplitude in the resonance region. In conclusion, the

ABSTRACT: It is shown on the basis of the equations of qua8ilinear
theory that the time variation of the background velocity distribution
function of plasma particles is such that the system reaches an equi-
librium state at infinite time, manifest by the formation of a plateau
on the distribution function of the resonant particles under the In-
fluence of three-dimensional longitudinal oscillations. The authors
consider the relaxation of the distribution function of electrons
moving relative to the ions under the influence of unstable ion-sound

oscillations. It is shown that if the electron velocity approaches a
critical value, above which the oscillations are unstable, then the
resonant electrons are decelerated during the initial stage of relax-
ation to velocities on the order of that of sound, after which a .
plateau Is produced along the beam direction. The oscillation spectn
then becomes one-dimensional. Whether a one-dimensional or three-
dimensional spectrum is produced depends on the volume occupied in
velocity space by the electrons at the initial and final instants of
time. The variation of the distribution function under the influence
of longitudinal oscillations In a magnetic field is also considered.
The equations derived are used to investigate the deformation of the
distribution function in the case of narrqi,,0M:_dimensiona1 wave

ABSTRACT: Coupled electromagnetic, plasma, and spin waves in 4ntiferromagnetic
4ezrdconductors and metals are investigated. Since there are two spin waves in anti-
~erromagnetics (unlike lerromagnetics, which have one), the spin and electromagnetic'
(plasma) wave interaction pattern in the former is more complex than in the latter._~
However, in anti ferromagneti cs the magnetic susceptibility is proportional to a sm*
parameter X0 (static susceptibility) , and the spin and electromagnetic oscillation
coupling is therefore weak. In the region in which the frequencies of the noninter-,
acting spin and electromagnetic (plasma) braches intersect, the frequency corrections
due to wave coupling is of the order of ~' -X_ , and far away from the intersection
0
region they are of the order of xo. Orig. ;rt. has: 32 formulas.

ITOPIC TAGS: plasma diagnostics, plasma density, plasma decay, microwave, electro-

ABSTRACT: Format's principle is employed to calculate the path of a microwave bean
in a cylindrical plasma in which the density decreases monotonically with imcreasing
distance from the axis for the two cases in which the beam lies in a plane containing
the axis of the plasma cylinder or in a plane perpendicular to the axis. For each case
there is derived an equation that gives the plasma density as a function of the dist-
ance from the axis implicitely in terms of the position at which the microwave be=
leaves the plasma as a function of the angle of Incidence. It is proposed that these
equations be used to determine plasma density distributions from microwave refraction
measurements. The proposed techniques were tested by measuring density distributions
in decaying hydrogen plasmas at-5 x 10-2 am Hg in a 2 a long 10 cm diameter quartz tub

and O.Pavlichenko (Atomnaya energiya, 16, No. 2, 99, 1964). Microwaves of 8 ms wave-
length were employed, and the radiating and receiving horns were provided with dielec-
tric lenses that rendered the beam nearly parallel. For each run the antennas were
held in fixed positions and the time after excitation of the plasma at which the re-
;fracted wave was received by the receiving antenna was recorded with an oscilloscope.
Many such runs were made with the antennas in different positions and inclined at
different angles, and from the accumulated data curves were constructed giving the
position of the antenna as a function of the incidence angle for different t:Lmes.*
From these curves the electron density lof the plasma was calculated as a furustion of
time and distance from the axis. Measurements were made both with the beam in a plane
containing the axis of the plasma cylinder and with the beau in a plans perpendicular
to the axis. Good agreement was obtained between the different measurements, and It
is concluded that the proposed techniques are satisfactory. The techniques can be
improved by employing narrower microwave beaus and shorter wavelengths. It Is also
possible to vary the'wavelength instead of the incidence angle. Orig.-art. has: 14

ABSTRACT: A quasilinear approximation has been studied for Cherenkov and cyclotron
attenuation of electromagnetic waves in a homogeneous magnetoactive plasna by taking!
illLo account coilisions between resonance particles responsible for the -.bsorption i
of waves and the remaining plasma particles. The velocity of resonance particles
along the magnetic field may be of the order of or less than the theri,,ial velocity.
For three-dimensional wave packets in the absence of collisions, the systern finally
reaches a steady state in which either the oscillation energy vanishes or the
distribution function has a plateau. In the case of Cherenkov resonance, diffusion
of particles on the waves in the velocity space occurs only along the magnetic field,'

of the field amplitude of Alfven waves and fast magnetoacoustic waves, propagating
almost parallel to the external magnetic field, possess different damping decre-
ments. The decrement difference is of the order of the inverse ion-diffusion time
on waves in a velocity space. It is also shown that the appearance of a "plateau"
in the ion distribution function may lead to a strong increase of the Cerenkov
absorption of Alfven waves (in comparison with the linear theory). In a plasma
with a low gas-kinctic pressure, the appearance of a "plateau" would always result
in a decrease of the damping constant. The cyclotron decrements of a fast
magnetoacoustic wave and of the ordinary and extraordinary waves may also
increase with increased field amplitude due to the "plateau" formation. The
authors thank A. I. Ahhiezer for his attention to the work and valuable remarks.

ABSTRACT: Propagation of a microwave beam through a nonhomogeneous plasma Is considet.-
ed as a diagnostic method for determination of the density distribution and electron
temperature in the plasma. Fermat's principle is employed to obtain a general expres-

'and angle of incidence. Detailed computation for the case of semi-infinite plasma is
!considered and the distance between points of beam entry and exit is found, as well as
tho inverse relationship for the density coordinates. This approach is extended to a
Ilaboratory plasma of cylindrical geometry. The temperature of the plasma electrons is
shown to be obtainable by observing the beam attenuation. The coefficient of attenva-

TOPIC TAGS: ferrite, spin wave, electromagnetic wave, plasma wave
ABSTRACT: In ferrites, as in ferromagnetics, there exist two spin-wa;ve branches, by con--
trast with fcrroma6-neties, which have only one branch. Hence it is toThe expected that the
picture of the interaction between spin waves and electromagnetic and plasma waves in fer-
rites must be more complex than in ferromagnetics. In this connection, the article investigates
the propagation of bound spin, electromagnetic and plasma waves in conducting ferrites with a
sufficiently large number of conduction electrons. If its frequency greatly exceeds the gyro-
frequency of electrons, the spin wave feebly interacts with electromagnetic waves: in the
neighborhood of the point of intersection between n~ninteracting spin and el6ctromagnotic
waves the interaction parameter is of the order of I/ V6, while at a distance f rom this point

it is of the order of 1/6, where 6_103 is the exchange constant. The spin wave of a frequency
of the order of clec~ron, gyr6frequency, -.on the other hand, strongly interacts with plasma
and electromagnetic waves (the coupling parameter is greater than or of the order of unity) so
that separation of the waves into spin and electromagnetic (or plasma) waves is possible only
in limiting cases.'In conclusion, the authors are deeply indebted to V. G. Barlyakhtar for

TITLE: Thermionic emission of some metal-like compounds in barium vapor,6'
SOURCE: Radlotekhnika i elektronika, v. 10, no. 12, 1965, 2200-2204
TOPIC TAGS: thermionic emission, electron tube cathode, ft-fc
71 ,
ABSTRACT: Results are reported of an experimental investigation of ther nia -i si=
and adsorption, In a barium flowof the following metals and their compounds: Ti, Zr, .40
Mo, C, TiSi2, ZrSi2, MoS:6, TiC, ZrC, MoC, TJ13~, ZrN , Mo2Br,. A special 6-cathode,
Mo-anode, JO-7-torr electron tube was used for testing the above materials; the anodes
had ports through which Ba, sunplied bya special source, flowed to the cathodes. Curves
of emission-current density vs. temperature are presented. It was found that the
carbides, borides, and silicides of the above metals have a lower emission than Mo
but higher than Ti and Zr. Although carbides have a higher melt point than borides,
the latter are more chemically stable. Carbides (melt point 3140-3530C),borides
(2980-3040C), and silicides (1540-1700C) have low emission in the Ba flow and,
therefore, can be recommended as anti-emission coatings. "The authors wish to thank
0. V. SamBonov for his interest in the work and practical help." Orig. art. has: 4

.rowth conditions based on most effective use of land and resources and creating
,ooiimal environmental conditions. Results of initial studies on the application of
'Cybernetics to plant growth were reported at an All Union Conference hold at the
'k:rophysical Scientific Research Institute in Leningrad (date not given). Thirty-seven
:papers were presented on the following four basic subjects: 1) general approach to the

:solution of problems and to the principles of applying cybernetics to plant growth;
'2) methods of obtaining data on plant conditions; 3) electrophysiological problems of
I
