TITLE: Excitation of magnetohydrodynamic waves in an anisotropic

PERIODICAL: Zhurnal tekhn:Lcheskoy fiziki, v. 32, no. is 1962, 44-47
TEXT: The study was carriod out by applying external alternating currents
The anisotropic plasma was assumed to be in a constant external magnetic
field ito long the z-axis in the presence of external currents Jos
Provided is sufficiently small, the plasma equations of G. Chew at al..
(Proo. Roy& Soc*t 236t M, 1956) can be linearized, and a Fourier
transformation applied. The dispersion equation thus obtained from the
determinant of the resulting system enables one to study the various
types of waves which might be propagated in anisotropic plasmas. The
following relation is derived for the emission intensity of magnetohydro-
dynamic and magnetoacoustic waves:

TITLE: Amplification of ion-cyclotron waves by an electron beam
SOURCS:_-Zhurnal tekhnict-eskoy fiziki,_v. 34, no. 10, 1964, 1803-1806
~TOPIC TAGS:- ohmic-plasma he~j ~n plasma.heating, ion cyclotron wave,

ABSTRACT% Ion-cyclotron waves can be amplified by an electron beam.
The energy of the directed motion of an electron beam can be trans-
ferred to the ions in the following way: The electron beam amplifies
the oscillations of plasma at a frequency close to ion-cyclotron fre-
queacy. As a result, part of tlie kinetic energy of the beam tran3-
forms into the ene-.:gy of the ion-cyclotron oscillations In plasma,
i.e., ions are heated loy an electron bean. In investigating tile con-
ditions for the most effective transfer of the energy of an electron
beam to the ions, it was found that amplification of the ion-cyclotron
waves.by the electron beam takes place when the beam velocity is suf-
ficiently high. With an increase of the Itnear plasma density N. the

ABSTRACT: The stability against low-frequency long -wave long th o5cillations of two
interpenetrating plasma streams moving in opposite directions parallel to a magne-
tic field is discussed theoretically. The temperatures of the two stream's are as-
sumed to he the same, -and the electron temperature is assumed greatly to exceed the
ion temperature. The dispersion equation is written for waves for which the fre-
quency is low compared with the ion Larmor frequency, the wavelength is consider-
ably groater than the electron and ion Larmor radii, and the component of the phase
------velocity Varq-11ol to the maf:notic field ie- low compared with the clectran anif high

ABSTRACT: The excitation of low-frequency electron-ion longitudinal waves i a Plasma I
by a beam of oscillators (i. e., a beam consisting of particles with an identical gi~ro_l
radius) 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 zh-in to be a delta function.~
The dispersion relation for the longitudinal wave is used to Investigate the damping co_~__
officients of various waves. A detailed analycis of the 11hct" beam and "cold" beam is
made. The criteria specifying the point at which the beam satisfies the above desig-
nations are established. In the case of the hot beam, only a emall fraction of the

~boam particles contribute both to the excitation and absorption coefficients. The lat-i
I
ter are explicitly derived. In the case of the cold beam, a similar analysis in which'
tlie.problem was broken down into several subca3es was made. At very low temperature
a1l particles were found to contribute to excitation; maximum increase in excitations
joccurred at particle resonance. Orig. art. has: 64 formulas.

ABSTRACT: The oscMations in electrZ6 beams with an uncompensated space charge in a
Brillouin regime is investigated in order to establish energy losses by Cerenkov radia-
tion. The beams considered here are infinitely thin rings, Idealizing system3 which
can be considered for accelerators and focusing schemes; the electrons move along the
waveguide surface. The equations of motion for a static case of a Brillouin cloud are
extended to include the high-frequency effects of the excitations, which are applied as
an impulse. The homogeneous 3ystem of equations is a Fourier system analyzed subject
-to the appropriate boundary conditions. It is noted that E-waves are excited. These
have identical dispersion relations with those of the electromagnetic oscillations in a
plasma column without the magnetic field allowing the author to apply the results of

ABSTRACT: The stability of two identical plasma streams moving along a static magnetic
field in opposite directions is investigated in the region interse--ted by the streams.
It is assumed that the streams are characterized by an electron temperature higher thar
that of the ions. The disipersion relation for the magnetosonic waves is written and
immediately simplified by ~he 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 Alf-ven
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 Is also showr

ACC NRi AT6020448
that more complete treatment of the pmblem predicts wave growth in the region where
there is no instability. However, the rate of wave growth is slight. Orig. art. has:

ABSTRACT: Excitation of elas waves moving normally to an external magnetic field by
a beam-of with identical Larmor radius (beam of oscillators) Is investigated. The
problem under consideration is limited to short wavelength excitations (much shorter
than the Larmor radius). Growth rate and frequency of the wave are taken to be much
gxv.ster than the gyrofrequency of the ions. This permits one to view the Ions as mov-
ing effectively1n a direction perpendicular to the external field. The contribution
of -the beam to the dielectric tensor of the plasma is described and the sums of each
of the elements in rewritten In terns of suitable integrals. This leads to a simpli-
fled expression for the elements in terms of wavelengths, which In turn yields the dis-
pervion relations. The latter am characterized by the presence of a resonance factor.
The presence of ordinary and wctraordinary waves is f-twther derived and the special

cases of propagation parallel and perpendicular to the field ar4i analyzed and the di-
electric coefficients obtained. The rate of growth of both wayes is shown to be com-
parable when the longitudinal and transverse ion velocities are the same and the plas-
ma density is high. It is also shovn that in dense -:)Iasma, instabilities foru when -the

ABSTRACT: A description is given of methods and equipment for
measuring air turbulence over Moscow, Sukhumi (Caucasus), and
Tashkent (Kazakhstan). One of the noozeworehy features of the
method is the synchronization of measurements of air turbulence with
Card

such parameters as air temperature, humidity, pressure, wind velocity
and wind direction. Turbulence was meisured mostly by balloon-borne
radiosondes with an A-22-III accelerometer attached. Sufficient
data have been collected (457 radiosonde ascents in 1961-62)
to determine a turbulence pastern over the aforementioned localities,
Turbulence occurs with the highest frequency in the 1-2 km ground
layer, it then decreases reaching a minimum at 6-7 km and then
reaches a maximum again at 10-12 km. Data were analyzed to deter-
mine other turbulence characteristics depending on location, season,
altitude, etc. It was roted that turbulence generally depends on
thermal and dynamic stri.tification in the atmosphere.and frequently
occurs during pronounced vertical *ind and temperature gradients. i
Two turbulent layers are frequently observed: one above the let
stream and one below It* Turbulence is minimal on the jet stream
levels It wav also observed that over Moscow and Sukhumi the
turbulent layer seldom exceeds 200-400 m and only over Tashkent at
5-7 km is it ever.. more than 1000 m thick& The experimental work
was carried out by the Central Asrological Observatory, Moscow. Also'

and the peculiarities of the capture and propagation of the plasma bursts have been
previously described by four of the present authors (ZhTF *34,1183,1964). In the pre-
sent experiments the plasma bursts passed through a 1.5 cm diameter circular aper-
ture In a screen located 30 cm from the point of capture and were observed at vari-
ous distances from the screen.with a "plasmascope". When the screen was of dielec-

ABSTRACT: The authors have previously t-Ound (ZhTF, 34, 43,'1964; DAN SSR, 157,
13350 i'964) that a portion of the plasma injected into a transverse magnetic feeld
is captured by the field and moves parallel to it'. They have continued their in-
,cstigatibn of this phenomenon (which is not understood) with an apparatus
simii,r*to that previously employed, but larger. In the present apparatus tho
longitudinal magnetic field Is maintained in a 12 cm diameter, 300 cm long dr7ft
tube; with the plasma transversely injected at the center of the drift tube, tho
motion of the captured plasma could be followed for 120 cm. The polarization of
t.-,,q captured plasma was obseried with probes. Alter a decrease of 20 to 50% in

froia the injection point. The expected.drift of the captured plasma in the
crossed fields (the electric field dud to polarization and,the applied magnetic
field) was obsarved with the aid'of a i;otted plastic diaphragm and a "plasmanscope"
(L.ItYelizarav and A.V.Zharinov, Nucl. Fos., Suppl., 2, 699, 1962). The effect of
shorting out the plasma polarization with P- copper disk was investigated; this was
found, in accord with the findings of D.A.Balcor. and J.F.Hammal (Phys. Rev. Letters,
1962), to Inhibit the transverse motion of the captured plasma. Orig. art.

ABSTRACT: This is a continua-tion of earlier inveGtigations of plasma captured Iby a
transverse magnetic field (ZhTF, 1964, v. 34, 1183 and elsewhere). Although the con-
ditions in the earlier invest igations wi.7;re such that no -instabilities could develop
in the plasma, the authors show that such instabilities can develop after the plas-
moid passes through a diaphragm -ahich in installed at a sufficJently large Iliatance
from the point of injection of the plasma in the ma~-rnetic field. At the large din-
tance from the injection point, the -olasmoid hao a -sufficiently large ratio of longi-
tudinal enerCV to transverse energy, and an appreciable density gradient. The in-
stability begins to develop in the region of raawimum plasma density, and the inhomo-
geneity of the density over the cross section of the plasmoid stimulates 'the develop-
ment of the instability. Arguments are presented in favor of classifying this as a

ABSTRACT: The authors 1nvesti[-,,-.terj Llie entrapment of hydrogen plasma bursts from a
17.5 cm long 7.2 cm diameter coaxial plasma gun powered by the 15 kV discharge of a
IS microfarad capacitor by a transverse magnetic field of strength up to 0.2 tosla.
The plasmas travelled from the gun to the transverse magnetic field through an 80 cm
long tube of glass or metal. The behavior of the plasmas was observed with both
electric and magnetic probes and with 4 mm microwaves, and the composition of the
plasma that traversed the magnetic field woo recorded with a parabola typo (Thompson)
mass spectrometer. The plasmas frog the coaxial gun had two components: a fast
component with a velocity of 7 x 10 rVsec and a relatively low density, and a slow
componenf with a velocity of 1.5 x 105 m/sec and a density exceeding 7 x 1013 cm-3.
The fast component was entrapped by very weak fields (0.01-0.02 tesla), and it is

concluded that it would be very difficult to inject these fast plasmas transversely
into a magnetic trap because they would become entrapped In the fringe field. Klen
the drift tube was of glass the slow plasmas were also rather rapidly entrapped and
did not reach the r,3gion of strong nagnetic field. Mhen the drift tube was of metal,
however, the slow plasma component tended to penetrate tho transverse magnetic field
and could be entrapped in a region of high field strength. The difference betwea.
the behaviors of the plasmas in the gliss and metal drift tubes is ascribed to short
circuiting of the plasma polarization by the walls of tho motal drift tube and conse-
quent deceleration of the plasma. It is concluded that --*or transverse injection of
plasma into a magnetic trap one should select an injector that produces slow dense
plasmas. The authors thank K.D.Sineltnikov and B.G.Safronov for vAluable disclissiono.

TOPIC TAGS: hydrogen plasma, plasma magnetic field, transverse magnetic field,

ABSTRACT: *This paperbegins with a brief theoretical discussion in the drift approxi-
mation of the adiabatic motion of a plasma in a nonuniform transverse magnetic field.
It is shown that the plasma is decelerated on entering a region of high transverse
0
magnetic field strength and accelerated on leaving such n region, owing to the trans-
formation of kinetic energy of forward motion into kinetic energy of rotation and vicel
versa. If the magnetic'field becomes strong enough the plasma can be reflected. The it
authors tested their theoretical conclusions by firing plasmas from a conical plasma
gun through an 80 cm long 7 cm diameter drift tube across a transverse magnotic field
Of up to 0.2Tproduced by a solenoid in a 12 cm diameter transverse tube. The magnetic
field gradient was adjusted with the aid of soft iron shields within the plasma drift
tube; these shields were covered with glass tubes to prevent the plasma from coming

in contact with them. The plasma gun war, powerud by tht-, 15 W dischnrge of a 15
microfarad capacitor and produced plasmas containing 7(ri. hydrogen ions with densities
of about 1014 cm-3 and velocities of about 2,5 x 10 ;" ,/see. The theoretical linear
relation between the square of the plasma velocity and the strength of the transverse
magnetic field was confirmed by the experiments. Plasmas with densities as low as
1012 cm-3 were obtained with the aid of an iris mounted in the drift tube. These
plasmas did not conform to the adiabatic theory, but were to a considerable f~ctent
entrapped in the transverse magnetic field, particularly when the field gradient was
high. It is concluded that low density hydrogen plasmas can be entrapped by a trans-
verse magnetic field of considorablo strength. The outhGra thank B,G.Safronov and
