TEXT. The a
uthors deal with the interaction between a.compensated
beam

of charged p
articles and the low-frequency oscillations of a plasma

(mainly with
the magneto-acoustic waves and the Alfven waves) in A

constant fie
ld in parallel direction to the beam and in the absence of

collisions.
If the plasma is rarefied to such an-extent that the

frequency Q
of the oscillations is much higher tha~.the frequency I ft
of

the collisio

ABSTRACT: The mechanism of the stopping of the growth of initial
fluctuations of Mac-
roscopic quantities in nonequilibrium plasma is investigated for
the case of an unbound
ed plasma. Following Landau's theory METF, 1945, 16, 574) a
general Fourier compo-
nent time development is obtained. The undisturbed equilibrium
distribution functions
which can be analytically continued into complex domain are
chosen for this study. Two
examples, where frequencies and damping coefficients are given by
the initial excita-
tion and do not depend on plasma property are closely examined.
It is shown that Dirac
6-singulari:~ies lead to undamped excitations, in
contradistinction to Landau's results.
This result is generalized to singularities in higher derivatives
and the asymptotic
form of the potential components is derived. The behavior of
t1,.! fluctuations is simi-

ABSTRACT: The author investigates an adjusted turnstile-junction,
to
arms I and 3 of which(there are altogether 4 arms) reflect-
ing pistons are connected. In the waveguides I to 4 waves of
the type TE10, and in the cylindrical waveguide, waves of
the type TE 11 are propagated. Also the two basis-polarizations
are shown in the drawing. The scattering matrix for such
a system may easily be determined from the scattering matrix
of a turnstile-junction by introducing additional relations
between the amplitudes a i of the inciding waves and the
amplitudes b. of the reflected waves in arms 1 and 3:

ai..'Mbi-ri, i - 1-3. Here _P. - e'Yi denotes the
reflection
coefficient of the piston in the corresponding arm; a 1 and
a2 - the eigenvalues of the scattering matrix, and it holds
that 11311 ' 1821 - 11. After several steps 4 equations are
obtained which may be written down also in matrix form.
The two special cases 7 = 1 and 7 = j correspond to the
application of turnstile-junctions described in
publications
(Ref 2) for the emission and for the reception of waves
with linear and circular polarization. Next, th- case:.is
investigated in which reflecting pistons with the
reflection
coefficients T 2 . eiT2 and P4 = eJT4
are connected also to arms 2 and 4 of the
turnstile-junction.
As before, the position of the pistons 1 and 3 is to
satisfy
the condition T 1 + 'r 3 '0. Also for this case a matrix
Card 2/4 equation is written down. This connection has no
losses,

and therefore the scattering matrix is unitary, The polari-
zations p and q of the inciding and of the reflected waves
respectively are connected by means of a broken-linear con-
nection. Because of the unitarity of the scattering matrix,
this transformation may be represented by the rotation of
a Riemann sphere round an axis passing through its center.
The points of the equator of this sphere correspond to pure-
ly linear polarizations, whereas the north- and the south-
poles correspond to the right-circular and left-circular
polarization respectively. By the difference in phase of the
waves reflected on the pistons 2 and 4 it is possible to
influence jqj . In conclusion, it is shown that in the case
of an arbitrary polarization p 1 of the inciding wave it is
possible to obtain an arbitrary given polarization q 1 of the
reflected wave. There are 4 figures and 3 references? 1 of
which is Soviet.

TEXT: - Most widely used methods are considered for measur-
ing small attenuations in waveguides, with modifications and
supp-
lements introduced as a result of experimental work in KhGIMIP.
An
analytical expression for attenuating an element-of waveguide
line
is considered. Methods described are: Substitution of a
calibrated
attenuator by the use of balance method, thermistor bridge,
circle
diagram, double three-port junction. Resonance methods
are,consid-
ered which are based on measurement of resonance resistance,
Q-fac-
tor and propagation coefficient of the investigated waveguide

as a resonator: 1) Method of equivalent transformer, 2) method
of
Q-measurement of waveguide resonator, 3) measurement of the
trans-
fer coefficient of waveguide resonator. Results are shown of
atten
uation measurements in waveguides by applying the first four of
the
above methods. The errors of the method of circle diagr&n and of
the method of equivalent transformer are considered in the
appendix;
also, the influence is considered of lumped losses inside the
meW
sured waveguide when methods involving standing waves are used;
fundamental data are given of the apparatus used for measuring
attenuation. 25 references. fAbstracter's note: Complete trans-
