the 8 lakes studied appeared to be connectcd with the
organic substances and Ca content. Increase of the or-
(pnic substances content, and also Ca to a definite
limit favored the Growth of these bacteria. An accumu-
lation of veakly acid orL~Anic substances depressed the
growth of Azobacter. Absence of bacteria of this ~xouP
in lake Ata and their slight growth in Jake Razno is ex-
plained by the low correlation between the content of
Ca and organi substances. Azobacter retained its viabi-
lity in soils of lakes at a low temperature and intense
oxygenous conditions in the near-bottom water layer.
In all samples of bottom deposits of the lakes studied)
bacteria of the Clostridium f,~Toup vere tuicovered.
Biochemical activity of bacteria of the Clostridium

homothermy was observed. The oxygen cycle in all the lakes except
in the shallow Durbe and Pikster, In which winter freeze-ups are
possible, is favorable. The mineralization of the lakes is average
and below average; the total ion content varies between 251.5 and
108 mg/liter. The ion content of th shallow lakes is somewhat higher
than that of the deeper lakes. The investigated lakes belong to the
calcium group of the hydrocarbonate class. By their organic matter
content, transparency, and color index, the Latvian lakes closely
resemble the reservoirs in the Valdaya range but have a somewhat
lower mineral content.

TEXT: This paper was presented at the 9th All-Union Conference
on Cathode Electronics, Moscow, October 1959.
The processes of diffuslon'and oxidation occurring during the
formation of effective emitters on CuAlMg and CuBe alloys are
examined, mainly on the basis of existing_literature, to obtain a
rational selection of activation conditions. Then the article
gives the statistical results of measuring the secondary electron
emission coefficient a and the coefficient of non-elastic
electron-reflection I in the medium-energy (200 to 2000 ev) and
high-energy (2 to 30 kev) primary-electron energy ranges. Non-
elastic reflection electrons are those with energies exceeding

,electron energy) are plotted. Witg mediuPm-energy primary
electrons amax varies from 10 to 15 and occurs in the region of
600 to 1000 ev. The value of I is approximately constant at
15 to 16% for MgO,fllm and at 12 to 13% for BeO film, formed on the
corresponding alloys. Curves are also given for the region
EP = 0-5 to 30 kev. Then a for normally activated CuAlMg alloy
has a maximum in the region EP = '1-3 kov after which it falls
sharply. A is approximately constant up to 2.5 kev and then
it increases to approximately 30% with increase of Ep.
When E EX (about 20 kev) q has Its value for the base
materiaY. hue the thickness of the aotivated film can be
estimated from the q(R ) curve and the values obtained (400 to
700 A) coincide appro2mately with those obtained by calculations
based on the activation conditions. The curves a(E ) and
ii(Ep) were obtained for samples having four different film
thicknesses (obtained by activation times of 1, 10, 20 and 60 min)
and the lower limit to the effective depth of the output of slow
,secondary electrons was obtained. For M*O it was approximately

TITLX:` Angular and Temperature Dependences of the Secondary
Emission Coefficient a and of the Coefficient of
Non-Elastic Electron Reflection n of Activated Alloy-
Type Emitters
PERIODICALs Radiotekhnika i elektronika, 1960, Vol-5, NO,10,
pp.1643-1649
TEM This paper was presented at the 9th All-Union Conference
on Cathode Blectronico,.Moscow, Octoberr 1959.
The use of alloy-type emitters in "dynode".particle multipliers
demands information on the physical processes occurring in such
emitters in different temperature ranges, in particular in the
range -60 to -70*C. This information is partly obtainable by
investigation of the manner In which the secondary-emisslon
coefficient a and the non-elastic reflection coefficient I
depend on temperature and on the angle of incidence T of the
primary electrons. The article in in three sections, viz
investigation of (1) the temperature dependence of a;
(2) dependence of a and I on the angle of incidence of the

MgO and BeO with a rough surface; (3) CuBe with a mechanically
polished surface. The results are presented graphically by
plotting vT/dO = f(T) for different values of primary electron
energies (Vp = 400, 8009 1200, 1500 and 2000 V). For all three
groups the following conclusions were drawn: a9/00 is large -
with large values of 4p; Cr /a0 increases with increase of Vp;
OV/00 is independent of angfe for V P less than 200 V. The-
degree of dependence on V is greatly affected by the surface
finish. j/%o increases with y and also vith the energy of
the primary electrons. The angular dependence a(y) is
explained on the basis of the simultaneous action of three
factors: (1) change in the conditions of formation of secondary
electrons as the angle of incidence of the prinuiry-electron beam
is altered, (2) the angular dependence of 1, (3) the micro-
finish cof the surface. In the third section, the apparatus for
investigation of the angular distribution of secondary electrons
is dencribed and illustrated. The polar diagrams (for T = 400*C)
for activated-CuAlMg are produced. The polar diagrams show the
distribution of secondary electrons and the distribution of
reflected electrons for normal incidence and for 20* angle of

incidence. The diagrams relate to VP = 500 V but the same
general shape holds for from 50 to 500 V. The distribution
conforma to a cosine law. Finally, the maximum of the energy
distribution of the secondary electrons does not depend on the
angle of incidence. This confirms the work of Gornyy (Ref.12)
but is in opposition to the results obtained by Frumin and
Kushnir (Ref.11). Acknowledgments are expressed to

ABSTRACT-.- nie dependence of the output power of an He-Ne laser on its various
parameters was experimentally investigated under conditions of short (0.5-osec)
pulses in rapid (2000 pulses/see) succession. A gas discharge tube with quartz
windows installed at the Brewster angle in a semi-confocal resonator was used. An
FEU-22 multiplication phototube served as the receiver. The output pulse shape of
the 6-mm and 15-mm discharge tubes was recorded by an 10-4 oscillograph. The depend-
ence of output light pulses with a duration of 30-100 Usec on the pumping power and
pressure of the mixture was investigated. The optimal Ne and He ratios in the tube

ABSTRACT: The dependence of the output power of an He-Ne laser on its various
parameters was experimentally investigated under conditions of short (0.5-psec)
pulses in rapid (2000 pulses/see) succession. A gas discharge tube with quartz
windows installed at the Brewster angle in a semi-confocal resonator was used. An
FEU-22 multiplication phototube served as the receiver. The output pulse shape of
the 6-mm and 15-mm discharge tubes was recorded by an 10-4 oscillograph. The depend-
ence of outpul' light pulses with a duration of 30-100 psec on the pumping power and
pressure of the mixture was investigated. The optimal Ne and Ile ratios in the tube
were 1 to 15 and 1 to 30 for 6- and 15--mm tubes, respectively. More powerful emission
occurred from 15-mm tubes (about I wt), with pulse poweraboutthree orders higher
than that under continuous emission. The average and peak output power of this tube,

4 mm Hg, and 10 to 22 kv for pressures from 6 to 12 mm Hg) shows, under pressures
up to 4 mm Hir, monotonically rising curves to about 30 kv. In the higher pressure
range, a narrowing of the emission zone occurs and the curves take the shape of
sharp peaks which shift with pressure toward higher or lower values and tend generally
toward higher output values at higher pressures. rcr a full explanation of these
relationships further investigations are felt necessary. The observations of the
cross-sectional intensity distribution within the output-beam revealed an multimode
structure. Under certain conditions-(pressure 4 mm Hg, pumping voltage 14 kv) the
beam cross section in the near zone took the form of a ring 12 mm in outside diameter
and 5 mm in inside diameter. At higher pressures and higher pumping voltages, a
delay and widening of the emission pulse as observed and explained earlier by Yegorov
and others (Optika i spektroskopiya, 18, 1965, 719; ibid '15, 1963, 839) took place.
Attempts to obtain emission from the same tubes on the 6328 X wavelength were un-
successful at. pressures of 1 to 8 mm Hg and pumping voltages of 6 to 30 kv. The

ABSTRACT- Absolute heat absorption (HA) values were determined for in
the course of an open-hearth heat. The investigations were car-
ried out in an 185-ton gas-heated open-hearth furnace (OHF)
with carburization with tar. The heat flows (HF) were measured
by means of a calorimeter of VNIIT design. The HF's vary
sharply in the course of an open-hearth smelting; the directflow,
passing from the flame to the hearth, varies more than the re-
turn flow from the hearth. A graph is presented showing the var-
iations of ihe direct HF along the hearth. The absolute value of
the direct HF is greater at the end than it is at the midway point
in the scrap-charging process. The return HF remains practi-
Ca rd 1/2 cally constant throughout the length and width of the hearth.

Heat Absorption in the Hearth of an Open-hearth Fu'rnace (cont.)
During the charging of scrap the HA varied from 340, 000 kcal/mZ at the
second opening to 140, 000 kcal/m2 at the fifth one. A similar nonuniformity
was observed in other stages of smelting also. The HF also varies from one
switching to another. The'variations of the direct and return:HF's in the
course of a smelting are shown in the form of a graph. The HA, which at the
time of charging of limestone amounted to 260-300 thousand kcal/Mz' de-
s ed to a v~.lu U , t
crea e., IMP.140 thousand kcal/mZ after the limestone had been
heated for a period of 3-5 minutes. An analogous situation is observed in the
course of charging of Fe ore. After the introduction of the metal scrap charge
into the furnace, the HA amounted to 260-340 thousand kcal/m2, but after 1.5
hrs of heating it dropped to a value of 140-160 thousand kcal/m2. At the end
of the smelting period and throughout the boiling stage, the HA diminishes
smoothly from 120- 160, 000 to 30- 50, 000 kca IlnnZ. The IIA is also shown to
be a function of the combustion rate of C in the hearth. The HA, which prior
to the introduction of Fe-Mn into the hearth had a value of 90- 120, 000
kcal/m2 (the hourly oxidation rate of C being equal to 0. 20-0.25%), is reduced
to a value of 40-551, 000 kcal/m2 three to five minutes after the introduction of
the Fe-Mn.
