ABSTRACT: Hitherto, the ionization of air by ions has been
investigated
mainly in connection with investigations of the unergy
dependence of the proton range (Ref 1), and icnization cross
section was only inaccurately determined (Ref 2). Direct
measurements of the ionization cross section in air by protons
are not known to the authors. In the present paper collisions
between positive hydrogen ions and air molecules are in-
vestigated, and the formation of secondary ions by the knocking
out of electrons and electron exchange is observed. The total
ionization cross section is measured by means of electron re-
Gording during the passage of an ion beam through air. The
simultaneous electron capture of H-ions was already investi-
gated by reference 4. The investigation of the componition of

spectrometer. Also the production cross sections for these
ions was determined. The measuring method was already des-
cribed in references 3 and 5 and is discussed in short. The
monochromatic ion beam penetrates into a collision chamber
in which air pressure amounts to 1.5 10-4 torr. It contains
a measuring condenser, which, by means of an ion current,
permits determination of 6+ and W- cross sections. The
total capture cross section is 6'10 ~ 61+ - 6,_, and for
the production cross section of secondary ions it holds that
GIA~%4 = � G'+ 04A" (C>CAy%.#= relative intensity of
An+-ions).
The total measuring error amounted to about -02 %, in which
case +6 % related to pressure- and +6 % to current measure-
melits. Spectrum lines were recorded of the following ions:
N+ 0+ N+ 0+, N++, 0++, Ar+, and in the residual gas

The present paper gives a report on the results obtained by
measurements of proton formation cross sections in a energy
interval that is between the intervals investigated by
references 4 and 5- Investigations were carried out in the
atomic gases helium and argon as well as in the molecular gases
hydrogen and air. Measurements were carried out in a mass-
speotromotrical device such as is described by references 8 and
9. The collision chamber and the analyzer used is shown in form
of a schematical drawing (Fig 1) and is described. For the
investigation of scattering a similar method was used as in
references 11 and 12. Measurements were carried out for
H+-pion energies (T) betreen 5 and 180 kev. The formation cross

sections for protons and H--ions were investigated; results are
shown by diagrams (Figs 2-5). For hydrogen and helium the
course

100 - 160 kev, and a smaller one at about 15 kev (Figs 2, 4)-
For argon and air the curve at first takes a curved, and from
about 40 kv onwards, a nearly linearly rising course (Figs 3,

TEXT. This paper gives the results of the measurement of
the full capture
cross section in the capture of one electron by protons
with an energy
of 10 - 180 kev in He, Ne, Kr, and Xe and of the capture
cross section in
the capture of two electrons in Ar. Furthermore, the
elastic and inelastic
proton scattering was investigated, which is connected with
the
transitions H +---b. Ho and H+oH-. A short description of
the measuring
method is given. For measuring the full capture cross
section the condenser
method was applied that had been described in the previous
paper (Ref. 6)
by the authore.The diagrams of Tables I - 4 show the curves
obtained
for the relationship between the energy T and the full

section in the capture of one electron by one proton in He, Ne,
Xr, or
Xe. Table 5 shows the.relationship between the velocity and the
full cap-
ture cross section in the capture of two electrons by one
proton in argon.
The analysis of these data shows that the full arose section in
the cap-
ture of two electrons decreases at T > 100 kev with the
increase in veloci-
ty of about v-9, i.e., it decreases much more rapidly than the
full cross
section in the capture of one electron (about v-.') in this
range). Table 6
shows the angular distributions of the protons of the primary
beam at
the residual and working pressure in the chamber, as well as
the angular
distributions of the neutral atoms 110 and the negative ions H-
which
were formed during the capture of one or two electrons by the
proton. UK
The slight extension of the(angular distribution of the protons
when the
cbamber is filled with gas curve 2) proves that the charge is
not
affected by the scattering of the protons. On the basis of the
data obtained
it is shovn that the capture of two electrons induces a
relatively closer
approach of the colliding particles than does the capture of
one electron.

In previous papers (Refs. 8, 9) issued by the authors'
laboratory it
was stated that the relative probability of the inelastic
processes in-
creases while the distance between the nuclei of the
colliding particles
decreases. The results of the present paper show that this
conclusion
can also be applied to the processes in the capture of the
electrons and
that this seems to be a general law in inelastic atom
collisions.

The electric and magnetic characteristics of a plasma
discharge are de-
scribed in detail, after which microwave studiesq spectrum
analysesp
and studies of the atomic flux emitted by the plasma are
discussed. The
experiments hitherto carried out on "Allfall show that the
production
and character of a discharge do not correspond to the
general concep-
tions of a selfcontracting quasisteady discharge. The
authors formed
this opinion owing to the lack of a long plasma column,
which follows
from measurements of the electric and magnetic
characteristics, from
microwave studies, from the existence of a large azimuthal
current,
from the asymmetry of discharge, from the occurrence of
oscillations
therein, and from a considerable inhomogeneity of plasma.
Besides, there
is an inhomogeneous hydrogen-ion distribution, which is
indicated by a
large quantity of protons with energies exceeding 10 kev. An
explanation
of these effects is not possible as yet. There are 8 figures

TEXT: The authors developed a method of measuring the flux of

method is
based upon the recording of individual atoms after their
ionization and
acceleration to 10-20 kev. Fig.1 shows a scheme of this
instrumentq in
which the ionized particles are directed onto an Al-Mg targetp
where they
produced secondary ions which were measured by a scintillation
counter.
For the calibration of the installation, a special device for
mono-
chromatic ions and atoms was used. The calibration curves are
shown and
discussed in detail. Further, installations are described in
detail,
which permit the time dependence of the atom flux, the energy

tus. The analyzer was described in detail earlier (Zh. tekhn.
fiz.
v. 30, No. 12, 1456, 1960). A fraction of the fast atoms
entering
the instrument was converted into ions by stripping on nitrogen
molecules. These ions were analyzed by energy in an electric
field
and then by mass in a magnetic field, after which they
proceeded to
the detector. The instrument was calibrated with auxiliary
appara-
tus described in detail in the same reference as the main
apparatuse
The various precautions needed to ensure precision are
discussed.
It was established that the plasma from the T-2 apparatus
emits an
atom flux with energy of hundreds and thousands of electron
volts.
A mass analysis of the secondary ions produced by stripping
the ni-
trogen atoms has shown that about -99% of the ions are
protons. The
only noticeable impurity was carbon-12. The main mechanism
produc-
ing this flux of fast atoms is neutralization of the plasma
ions via
charge exchange with the atoms entering the plasma. The
conditions
for the occurrence of this flux are estimated. Preliminary

ABSTRACT: A stabilization method involving direct control of the
beam position
in a measuring outfit is"proposed. The princi 1e is illustrated in
Fig 1. (see
,P
EInclosure 1) where the iypical effect Of the ac.6elerating
voltage on the beam
current can be seen. A modulating sawtooth voltage, whose
amplitude is small ins'..
cqxnparison with the half-width aU of the line', is added to the
d-c accelerating
voltage. Modulating -frequency pulses appear in the circuit which
records the
beam current; the amplitude and polarity oll these pulses will
depend on the value

of the accelerating voltage which makes the del~tection of variations in the
accelerating voltage possible. The latter is controlled by the d-c component of
the pulses. This type of stabilization. is independent of the spectrometer
resolu-
tion. A functional diagram (see Fig Z, Enclosure 1) and principal schematics of
the sawtooth-voltage generator and balanced detector are presented. It is
claimed that the beam can be easily stabilized up to 10- amp intensity and that
the functioning time is 0.01 sec. "The authors are deeply grateful to X. V.

v. 34, 1613)
1624, and 1637, 1964) of the elementary acts of collisions between
ions and argon
atoms having kev energies at impact parameters smaller than the
atomic dimensionsp
where it was found that the spectrum of the excess inelastic loss is
not continuous,
but consists of relatively narrow discrete lines, the energies of
which do not de-
pend on the shortest distance between the nuclei, on the relative
velocity of the
particlesp or on the scheme of the elementary process by which the
charge states are
changed. Th determine the extent to which the observed phenomenon is

authors investigated collisions between ions and atoms of different

served in the investigated interval of shortest distances between the
nuclei of the
colliding particles. The regions in vhieb one R* line is excitedp and
the region
where the transition occurs from excitation of one line to excitation
of another., do
not shift when the relative particle velocity changes. However,,
excitation of lines
with different energies vere observed when the velocities were
different. Analogous
results were obtained for JW~ + Kr pair at 25 and 50 kev. In this
case., three char-
acteristic R* lines were observed in the interval 100--600 ev. For the
Ne*' + Ne pair
at 50 kevp one R* line with energy -160 ev was observed. The authors
investigated
the connection between the excitation of the characteristic lines and
the charges of
the colliding particles. When like particles collide ("symmetrical"
pairs Ar-~ + Ar,
Kr+ + Kr) this connection is manifest in a clear-cut correlation
between the average
charge of the scattered particles and the inelastic energy loss. No
such correlation
is observed when an %#Wmmetrical" pair is investigated (Ne+ + Ar,
energy 25 kev).
Tbe- scattering of the colliding particles was also investiged in
detail. It was
found that the total differential scattering cross sectio"n is not, as
beretofore,.as-
sumed,, a continuous function of the scattering angle,, and
singularities are observed
',,when the measured cross sections are compared with the cross
sections calculated for
a continuously varying interaction potential. In the transition
regionj, the
mental scattering cross sections differ most strongly from the
calculated one n,virti;

present an unambiguous interpretation of the observed effects. The explanation
offered earlierj based on the assumption that vacancies are produced in the

ABSTRACT: A technique for measuring the charged particle density of a hydrogen
plasma with the aid of a beam of high energy (5-20 XeV) hydrogen atoms has
been
developed and tested by measuring plasma densities in thelAllfa"
installation., The
method has the advantages of good sensitivity# negligible Interference with
the plasma
and independence of the physical state of the plasma and the presence of
magnetic
fields. The injector consisted of an ion source, accelerating electrodes,
electro-
static deflecting electrodes for directing the beam, a charge exchange
chamber con-
taining hydrogen at (1-4 x 10-4 um Hg in which some of the ions were
neutralized,
and a transverse electric field which removed the unneutralized ions. After
travers-
ing the plasma the hydrogen atom beau passed through a transverse electric
field
which cleared It of any charged particles that It might have picked up, and a
charge
exchange chayber in which some of the atoms became Ionized. The Ions issuing
from

the charge exchange chamber were analyzed by means of electric and magnetI6
fields
and those with the proper energy and mass, corresponding to the energy and
mass of
the inittalprobe bean particles, were recorded with a scintillation
counter. The sen-
sitivity was such that a beam current corresponding to 10-10 A of
singly-charged ions
could be employed. The injector and detector assemblies were enclosed in
Iron housingg
of approximately 1 cm wall thickness for magnetic shielding. The plasma
density was
calculated from the attenuation of the beam on traversing the plasma. The
theoretical
discussion Is facilitated by the fact that once a beam particle Is ionized
it Is re-
moved from the beam by the ambient magnetic field, so that the possibility
of t~e ion
becoming neutralized again does not have to be considered. The most
significant beau
attenuating process Is shown to be resonant charge exchango with plasma
protons;
ionization by electron impact is also significant, but othor processes are
negligible.
The effect of scattering of bean atoms was partly eliminated by comparing
the attenu-
ation of the beam by the plasma with its attenuation by an equivalent mass
of union-
ized gas, and the residual effect of scattering was.shown experimentally to
be imper-
ceptible. The attenuation of the bean was independent of bean energy over
the investi-
gated range from 4 to 20 keV. The attenuation of such high energy beans 19
nearly
independent of the plasma temperature. The decay curve of the plasma in

distance of closest approach; the positions of the lines, however, did
depend somewhat
on the Incident Ion energy, The curves roprosonting, the composition

revealed regions o
slow and rapid change associated with excitation of the different

and the differential cross section deviated from a smooth curve at

between the characteristic lines excited in Ne+-Ar collisions and
those excited In

ABSTRACT: Apparatus is described which permits the characteristics
of crystal txiodes to be displayed and photographed on a CRT
screen. The data obtained can be used graphically in the
design of circuits using crystal triodes, and also for the
investigation of the triodes theriselves. The characteristic

given in Fig.1 where 3 is the emitter and k' is the collector.
T11,e voltage from the transformer is applied to a crystal triode
through a resistance R connected in series with the collector.
The voltage developed across the resistor R, which is propor-
tional to the collector current I., is applied to the vertical
plates of the URT; the collector voltage U K is applied to the
horizontal plates. A step voltage/current generator is

ABSTRACT: The author examines the nonstationary distribution
of temperature
in a flat sector-shaped area bounded by two circular arcs and
two
segments of radii. The solution, obtained by the Fourier
method, is
in the form of a series. The convergence of this series is
not inves-
tigated; individual instances corresponding to various
conditions of
heat exchange through the boundary of the area are studied.
Thermo-
elastic stresses and displacements corresponding to
temperature
conditions investigated are not examined.

TITLE: Construction of Closed Irrigation Pipelines in Georgia
PERIODICAL: Gidrotekhnika i melioratsiya, 1959, Yr 9, rp 15-17
(USSR)
ABSTRACT: It was established that in the mountainous regions
of Georgia it is more expedient to use -- instead of
open irrigation canals -- the closed asbestos-cement
waterpipes. In order to obtain the maximum operating
efficiency of such pipelines, natural gradients are
to be made use of; the pressure in the pipes sho-old
not be larger than that required for temporary sprink-
lers. The pipe diameter is selected, depending on the
water outlets. (Table on page 16). The layout of
pipelines with diameters of 200 to 400 Mm is ex-
pressed by formula i + 4~,h where i is pipeline
f
gradient; if - gradient corresponding to friction

Construction of Closed Irrigation Pipelines in Georgia
between the wells; Ah = pressure at the temporary
sprinkler. The waterflow speed in the pipes should
not exceed 6 m/sec. The wells used for this irriga-
tion system are of a semi-automatic water outlet type,
Of late, a well construction designed by T.D. Suladze,
M.I. Machavariani and R.A. Agababov came into use
(Fig on page 17). The well operates on the principle
of extinguishing the kinetic energy of intake water
and of passing it on without extinguishing the transit
consumption. The cost of building of such wells is
nearly 401~- lower than of those ma-de until lately.
There are 1 table and 1 schematic diagram.

TITLE: The adfa-ting Properties of Furnace Slags (Izluchatel,naya
sposobnost' topochnylkh shlakov)
PERIODICAL: Teploenergetikaj 19581 Nr 8, pp 56-6o (usm)
ABSTRACT: A knowledge of the radiating properties of furnace slags
is required for calculations of the heating of boiler
surfaces covered with slag. There are some doubts about
the values of the blackness factor of slags, which are
thought to be about 0.8. This article describes deter-
minations of the blackness fac "or of furnace slags in the
solid and liquid oonditions and also of the radiating
properties of various vitreous substances of analogous
composition. An equation is given for the radiation from
solid slag and glass, This depends on the ratio of the
radiation temperatures determined by a radiation pyrometer,
to the true surface ternqparature7 determined by measure-
ments of the grad.-Lent within the specitiGn using platinum/
platino-rhodium thermv--couplea. Slag is very brittle and
of high melting point. Thus it is very difficult to

fiold. Suitable specimens wore, therefore~made of glass.
In the sample of slag, the temperature was measured at a
depth of 1 mm. The surface temperature was determined
from the results of tests on class; this is permissible
because the thermal conductivities of the material are
similar, The arrangements of tlie the-Mo- couples in the
glass samples are illustrated diaggrammatically in Fig 1
and photographs of samples nambers 5 and 6 (see Table 1)
are seen in Fig 2. The formula used to calculate the mean
surface-temperature is given; the temperature so derived
was used to calculate the radiating ability, using
formula (1). The slag sample with th9rmo-Couple is
sketched in Fig 1r; in some cases the surface of the sample
was ground, but in othaTs the natural surface obtained on
cooling was used. When the slag or glass is molten, the
thermo-couples cannot be positioned accurately and so the
true surface temperature cannot be determined. In this
case optical methods based on measureL.-ients of either the
Card 2/4 brightness temperature or the brightness and
radiation
temperatures are used to detorraine the blackness factor- for
