"Stability of Relativistic Electron Beams in a Plasma and the Problem of
Critical Currents"
Moscow, Uspekhi Fizicheskikh Nauk, No 4t Apr 71, pp 609-640
Abstracta Recent research in high-current electron accelerators, which have
become a subject of renewed interest due to recently expressed ideas con-
cerning using powerful relativistic electron beams -to imuduce controlled thermo-
nuclear reactions and for onera over great distances, is
surveyed. Topics covered include limiting currents in uncompensated electron
beams, critical currents in compensated unbounded electron beams, the effect
of finite longitudinal dimensions of the system on critical currents In the
electron beams, the interaction of an unbounded relativistic electron bean with
a plasma, the stability of -a bounded electron beam in a plasma, a-rid critical
currents of relativistic electron beams in a plasn-a. It Is shown that the
inattibility of an electron beam pasuing through an ion shell determires the
limiting current in a compensated electron beam. In the case of nonrelati-
vistic beams this current is only several times greater than the vacuum

Uniting current determined by the space charge of electrons of the beam.
The situation is different in the case of relativistic energies of beam
electrons. It is shown that the critical current in a ra~ativistic compensated
beam can exceed the vacuum current by a factor of (E/mc~-)e, where E is the
energy of the electrons. It is noted that this rise in current is possible
only when current-convective instability does not develop in the system. The
theory of the stability of electron beams in a plasma is examined from the
aspect of explaining those critical parameters of the plasma and beam under
which some form of collective interaction arises in the bounded system. As
regards systems with an overcompensated electron beam, it is shown that in
the interaction of a relativistic electron beam wilth a plasma. the relative
loss of beam energy to excitatioa of oscillations is of the order of
(E/ZC2)(n,/n 2)1/3, where n1and n. are electron densities in the beam and
in the plasma, respectively, When this quantity is ,small, energy losses of
the beam and the energy spread of the electrons are slight, and desDite the
fact that conditions for the development of instability are fulfilled in the
system, the beam passes through the plasma practically without change. It is

stated that in this case one whould speak about critical currents in the system,
as distinct from the case of strictly compensated beams, when the beam loses
a considerable portion of its energy as a result of the development of
Bunezan instability and undergoes essential changes, so that critical currents
In compensated beams are simultaneously limiting currents. The final section
of the survey is devoted to a comparison between theoretical ideas developed
&rA experiments on the interaction of electzvn beams with the plasma formed by
them.

Abstract.: Tna aosorption of electron cyclotron waves in a -rarefied plasr-.zi
is investigated t-nder cond-itions when the Larnor frequency of the eleccrons is can-
siderably greater than the plasma frequency, Under these conditions in a spatially

an ordinary wave is practically not absorbed. In a bounde(i plasna, such as a
wavaguide filled with plasma, the absorption of an ordIna,17; WaIlle -Mav become

The interaction between the limited relativistic electron beam
of a small density and plasma being In a strong !ongitudinal inag-
netic field is investigated. Thi critical plasma dtnaity, above
wbich the electrobtatic instabilities may be developed, Is deter-
mined. In long enough systems, the critical density Of P13SMR 18
tacreased writh the grouth of Its density reaching some value de-
termined by the directed velocity of electrons and the geometrical
dimensions of the system. In the system.s limited in a longitudinal
direction, the critical density of plasma may be dependent also on
the system length and magnetic field intensity. [a this case the
critical density Is larger than for a long system. It follows from
the analysis of the stability that the maximum current of the elec-
tron beam, %bich may be passed through the wavegu:de, Increases
in the relativistic region with the growth of the electron energy as
0. Due to this possibility. large currents may penetrate through

. The absorption of the cyclotron electron waves in a confindd
and rarefied plasma was investigated when the Larmor frequency
of electrons exceeded considerably that of the plasma. Under smch
conditions the extraordinary cyclotron wave is absorbe-d rather
strongly In a spatially unlimited plasma. while the ordinary wave
Is practically no, absorbed at all. In a limited plasma tfor exam-
ple, a waveguide filled with plasma), due to the interaction of
,v-aves at the plasma boundary, absorption of the ordinary waves
may become anomalously M~h if the wave length is of th-e order
of the plasma dimension, At this, the absorption factor bixomes
an oscillating function of the wave length and system dimensio0s.
Cases of high -temperature plasma without collisions and of cold
plasma with a great number of collisions were examined. Recent
experiments on absorption of the cyclotron waves in a limited
plasma are discussed on the basis of the newly developed theory.

a resonator in a semiconductor laser with electron beam pumping. It is
shown that modes of a waveguide type are excited in such a resonator, as a
result of which the os cilia tion,threshold is independent of the electron
energy and the directional diagram has a more complex structure than in a
homogeneous resonator. Use of the resonator makes possible a reduction
in the oscillation threshold to 0.3 a/cm2 (in the electron energy range of
15-20 kev), which is less than in a laser with a homogeneous resonator by a
factor of 1-2. 9 ref. Authors abstract.

"Some Possibilities of Applying a Semiconductor Laser with Electron a-citation
in Computers"
Moscow, Radiotekhnika i Elektronika, Vol XVI, No 5, May 1971, pp 824-828
Abstract: A study is made of the requirements on a cathode ray tube based on
a semiconductor laser with electron excitation beginning with the problems of
creating prospective optoelectronic memories. Experimental and theoretical
results confirming the possibility of satisfying these requirements are pre-
sented.
The threshold current density is plotted as a function of the electron
energy for various sizes of the excitaud domain d and reflection coefficients
of the mirrors. With a beam energy of 100 kiloelectron volts and a current
density of 10 amps/cm2 from a cell 210 microns in diameter, the output power
was 5 watts, ard the conversion efficiency was 1.5 percent. Since the pulse
length of the electrons in the bean, was 10-7 seconds, the radiation energy was
5.10-7 joules. Consequently, in order to obtain the radiation energy of

other equal conditions, the size of the spot on the laser screen of the cathode
ray tube has to be about 100 microns. The pulse power of the radiation will be
1 watt and the mean power, 10-2 watts, and a screen with 105 positions will be
about 40 x 40 m. A screen spot size up to 300 microns is required to insure
a read rate of 109 bits/second.

Abstract: ~Va analvsis of continuous mass production systems in various sectors
of the national economy conducted at the Odessa Technological Institute imeni
M. V. Lomonosov made it possible to isolate the general functional singularities
of various segments of the systems and to reduce them to eight types. The class-
ification of segments of the continuous mass production *ystem and tile principles
of setting up a dispatcher automated control system on this basis comprised of
standard general-purpose modules were taken up at the Third All-Union Conference
on Automatic Control. The analysis was based on the example of a modular dis-
patcher automated control system for the most complex production line segment
requiring sixteen modules. Further studies showed that the number of modules
required for realization of this segment can be reduced to tea. It is shovn
that further automation of continuous mass production systems should be based
on a transition from dispatcher automated control to operatorless programmed

control. This will require analysis of the dispatcher's functions for purposes
of algorithmic description, classification-of the dispatcher's functions, and
a description of the information which must be stored. A simple formula is
found for the optimum control system from the standpoint of cost. it is shown
that the function of route analysis can be handled by an automatic device with-
out extensive modification of the dispatcher control system.

"Telescope for Recording Low-Energy Protons Against an Intense Beta Background"
Moscow, Pribory i Tekhnika Eksperimenta, No 5, 1972, pp 28-30
Abstract: A study was made of the problem of lowering the sensitivity of a
telescope system to electrons in order to make it possibl,-: to record protons
with E less than 1.0 megaelectron volts. A telescope is described which com-
prises 2 planar proportional counters and a semiconductor detector designed for
spectrometric analysis of low-energy protons (0.5-6.0 megae-lectron volts) in the
presence of intense a and y radiation backgrounds. Utilization of compari-
sons of the proportional counters in the control channel essentially reduces
the 0-background of the semiconductor detector by comparison with the case
where only one counter is used for the control. With variation of the thresh-
old in the control channel the intensity of the spectrum varies uniformly in
accordance with the hypothesis of independent formation of the spectra in the
two counters. The introduction of a 3.0 kiloelectron volt threshold in the
control channel leads to a twenty-fold reduction in intensity of the count
with respect to the entire spectrum of the first counter.

Abstract: TIie electromagnetic characteris tics of 1-aulticircuit liallf0pen filLers
and the ::emperature functions of) these filters -- direct losses, resonance
curves, decoupling, suppression of spurious resonances and thermal stability
characteristics -- were obtained experimentally in order to check the known,

of such I!ilters. The ferrite resonators were installed in t1he round holes of
metal diztphragms, and a constant magnetic field was applied. The diaphrapmn
were arranged at a variable distance from each other, and tile input and Olitput
ferrite resonators were located so that an intermediate ferrite resonator
could be inserted as a third circuit. Investigations in the 3 centimeter band
demcmstrated --',,at with an increase in the diameter of the ferrite resonators
the minimum loss region corresponding to the critical couplings is shifted
towards large distances butween the filters, and it becoines less expressed as

with an intermediate resonator, within the limits of 02-63 ducLbels in a br3ad
frequency range. With orientation of the ferrite filters on the [1101 axis,
the thermal variations of the losses are noticeable especially in the positive
temperaUire range. The thermal effect on the parameters and characteristic:; of
sern-open filters can be reduced significantly if the ferrite resonators o.-F
the filters are oriented independently.(in the sense of coupling) along the
isotropic axis. The frequency drift obtained for two coupled ferrite resonators
(67 kilohertz/degree) indicates high thermal stability of the investigated
halfopen filters.

Abstract: A study was r.,iade to obtain a set of relations necessary [or calcu-

filters. The method developed previously [A. L. Mikaelyan, V. Ya. Antonyats,
Radioteklinika i elektronika, Vol 7. No 4, 623, 1962) was exterded to halfopen
systeru, in order to obtain the relations. There is a noticeable effect fro.n
the coupling coefficient an the st-tape of the resonance frequency curve, Mag!leti-
zation, size and otiier parameters of the ferrite resonators. In a number of
cases this fact can require regulation of the couplinS coefficient when tun.-ng
coupled ferrite resonators in a broad range of variation of the frequencies
and external conditions. Ilie coupling coefficient of the halfoper. farrite
resonators (in contrast to closed ones) can be regulated quiLe st-iiply by
varLous technical procedures as a result of the presence of a free space bci-
tween the segments of the wave guide lines with ferrite resonators.

as a result of the study are discussed. The aerodynamic paraeters ,er- fotind
by mathematical neans: the permeability coefficients and the macroroughness
which enter into the equation for the intermediate law of motion for the air.
The quantitative values of these para-meters obtained for diHerent r-notions of
the air were deternined experimentally under mining conditions. It was also
established that the permeability coefficient varies in inverse proportion to
the chann-e -1--i zn~- aerc,-N-Lia-mic resistance ar,,2 that the rougnness is in-
versely proportional to the change in the square of the aerodynamic resistance.
