Title : Cascade grouping of electrons in application to the theory of the mu-Itire-
sonator magnetron
Periodical: Zhur. tekh. fiz.., 25., No 8 (August), 1955, 1462-1470
Abstract : The author states that in earlier works on this subject the methods of cal-
culation adopted by the authors yielded only the boundaries of the self-ex-
citation regions of a generator, and in addition only theoretical magnetrons
with infinitely thin cathodes we *re considered, making the complete applica-
tion of these results to magnetron construction impossible. In this article
the author considers a magnetron with "thick" cathode. He analyzes forms of
oscillations different from the pi-form, finds self-excitation and stationary
oscillation conditions, and derives an expression for complex electronic con-
ductivity.

ABSTRACT: The process of phase focusing in a reflex klystron with a finite transit
time of electrons in the cavity is considered. In actual tubes, this time is
within 1/4 - 1/2 m, where m is the period of oscillations. The moment tj of
electron arrival in the cavity is selected as an independent variable for transit
angles and electron velocities. With the transit angle 251- v02 - The streams interact with each other

With regard to the interaction of the spatial harmoni'cs it is
found that the whole operating range of 'he system can be divided
.L A.6
into a set of interaction bands, where the signal can increase
and stability bands where the increase of the signal is impossible.
The case. of two beams moving in opposite directions with identical
velocities is also considered and it is found that t-he discrete
interaction of two such beams leads to the appearance of the
Interaction bands and stability bands so that this case differs
.Lrom that of the cont:Lnuous interaction. While the propagation
constants of the system were determined from the scattering
equations, their amplitudes are determined from the initial
conditions at the input of the system. Also, by considering the
boundary conditions it is possible to-derive general formulae
for the amplitudes of -the partial waves and for the gain of the
system. The conditions of oscillations for two electron beams
propagating in opposite directions are also-determined.

TITLE: Effect of reflections on the operation of backward
wave tubes
PERIODICAL: Radiotekhnika i elektronika, v. 8, no. 1, 1963, 99-107
TEXT: The durpose of the paper is to ihvestigate theoretically the
startin,-- current and efficiency of bac1niard wave oscillators in the
presence of space charge and finite reflections. If a part of the
circuit wave is reflected then the condition.of oscillation is no
longer infinite gain but instead the product of gain and reflection
coefficient must be unity. The gain is-calculated on the basis of
two earlier works by Shevchik (Osnovy elektroniki SVCh (Fundamentals
of microwave electronics), Izd. Sovetskoye radio, 1959;~'Radiotekh-
nika i elektronika, 1960, V. 5, no. 12, 2059). The solution is ob-
tained by successive approximations where, in the zero order appro-
ximation, -he aMpl4tude of the circuit wave is taken as constant
and its phase varying as exp j(G)t Sz). The gain is calculated.by

'electron be4m in fields of homogeneous transmission lines can be describeii ~wxth the
of an infinite number of electronic waves. Each of the waves,corres~onds to a
definite distribution function of the variable current density over the beam cross
section. The aggregate of the distribution functions forms anortbogona~ system on
the cross section of-the transmission line.. The propagation constants of the waves
are determined either from a dispersion equation of infinite degree,-or from an in-
finite set of dispersion equations of fourth degree. A general-solution is obtained
for the coefficient of reduction of the plasma frequency in a screened electron beam.

the interaction between the electron beams and slow waves and to the behavior of

PERIODICALt Vestnik statistiki, 1956, Nr 11, PP 30 - 39 (USSR)
ABSTRACT: The author divides the basic funds, which represent the
most important part of the USSR national wealtht into pro-
ductive and unproductive capital. During the period of
the 5-year plans the basic funds of the national economy
increazed considerably. During WW II the basic funds were
largely destroyed in the occupied districts but even then
the process of creating new basic funds did not cease.
The post-war years were characterized by an exceptionally
turbulent growth of these basic funds. For a proper plan-
ning of reproduction, further growth and qualitative im-
rovement of basic funds, especially the productive ones,
p
a well organized inventory is of great significance. It
should give an exact idea of the size, composition, techn-
ical level and real condition of the assets. The organi-

regulations covering bookkeeping, capital investments
registration and the bringing into operation of basic
funds, their classification, etc. In the enterprise
balances, basic funds are specified at greatly varying
prices depending on the year of their manufacture or pur-
chase and methods of construction. This greatly impedes
the registration and planning of reproduction of basic
funds on an expanded scale. The reappraisal of the nation-
al economy's funds is a major and difficult operation.
Several difficult methodological problems (methods of
establishing the restoration value, amortisation, etc.
must be solved. The participation of not only finan-
cial workers, bookkeepers and statisticians, but also of
engineers and economists is needed. Thorough prepara-
tory work and active cooperation on the part of enter-
