PERIODICAL: Fizika tverdogo tela, v. 3, no.. 2.. 1961, 588-594
TEXT: The ion-induced electron emission from dielectrics and
semiconductors
has heretofore not been systematically studied; on the other
hand, this
study is necessary in order to get an insight into the
mechanism and under-
lying rules. Studies in this respect were ti.,erefore conducted
on r.-type
germanium single crystals (resistivity 37 ohla-cm), and results
are described
Jn the present paper. The disk-shaped Ge crystals (6-7 mm in
diameter) were
ground, etched with CP-4 (9R-4), and washed in distilled waters
Subse-
ontly, they ivere introduced (M) into the oxperimental setup
(Fig, 1)~ The
apparatus had a residual gas pressure of not over 5''0-8 mm
119; ovacuation
took place with a mercury diffusion pump, The positive ions
were emitted
from the hot source (0) which was coated with a paste made of

The target
temperature ranged between 700 and 8000C during the (static)
measurements,
and the primary ion beam had an ampera(~e of 5,10-6 a The
e'lectron-emission
coefficient y was measured as a function of the ion energy;
the results tire
illustrated by Fig. 2. y grows linearly with E for Cs, K,
and Li; the in-
clination of the y straight lines is the same as in the
bombardment of
metals; for all alkali ions there is a threshold energy
(1000 ev for Cs,
about 500 ev for K and Li), above which the kine t4C
ejecting of ions be-
comes considerable. Mass-spectroscopic studies showed that
the ion beams
used were by 98~o ions of the same type, The curve obtained
for IU -, ions
(at 5000C target temperature) shows that field-induced

TITLE: Emission of an oxide cathode bombard:!d by charged
particles
PERIODICAL: Fizika tverdogo tela, v. 3, no. 2, 1961, 567-574
TEXT: Abroyan has shown in two previous papers that a beam
of potassium
or hydrogen ions incident upon the surface of an emitting
oxide cathode
gives rise to an increase of the anode current, with A = 6
Ia/I 1
attaining up to 5000 electrons per ion ( 61 a, change of
electron current
of the cathode, I,, intensity of ion current at the
cathode). Further
studies have been made of the effect of different positive
ions upon the
thermionic emission and the mechanisms of the change of the
thermionic
cathode current. The measurements were made on an apparatus
described
earlier at 1-2.10-7 mm Hg. The primary pulse currents had a
duration of
10-200 psec and a frequency of 2-2000 cps. The primary and
the secondary
pulse currents were recorded by a linear amplifier with
resistors

ensuring the conservation of the pulse shape. The pulse
heights were
measured with an C~4-1 (SI-1) or 25-W(25-I) synchroscope, Oxide
cathodes with coatings of (Ba,Sr)O and (Ba,SroCa)O were
utilized, and
the effects of ion bombardment were found to be "'airly equal
for both
types. The typical dependence of L\ on the energy of
bombarding ions
is repreqented in Pig. 1 for 6.5 v at the hot cathode, and an
anode
current of 1.2 ma; (for eieotrons (I), hydrogen j,ons (2),
helium ions
(3), and argon ions W, as well as. in the case of U. ath ~ 5.5
v and
Ia= 1.4 ma, potassium ions (5)), Experiments with K; were,
however,
conducted with another cathode, so that the results are not
comparable.
The monotonic decrease of L~ kfrom 2.5 to 10) observed in
electron
bombardments of the cathode fits ob!;ervations made by
Pomerantz.
L\ as a function of the plate voltage Ua first exhibits an
exponential
rise -ap to about 60 v, and, with a further increase of Ua the
rise is
slow and practically linear (on a bc-mtardment by 2.rj-kev

potassium ions, -10 liseoo The results show that the change
of the
emission of an oxide cathode bombarded with positive ions
cannot be
explained by the slowing down of ions, The safest
assumption seems to
be that so-called "displacement defects" are formed in the
surface layer
of the oxide coating, i.e., defects caused by a
displacement of ions
from their positions of equilibrium in internodal
positions~ This
assumption is above all supported by theoretical
considerations. The
following formulas are obtained for the penetration depth 6

TEXTs The additional conductivity of n-type Ge i6duced by
bombardment
with a pulsed beam of potassium ions (100 - 10,000 ev) was
studied with
an arrangement similar to the usual.secondary-emission
apparatus (FTTI 31
2, 588, 1961), comprising a spherical collector, an
antidynatron grid, and
the Ge target. The samples had previously been heated to about
8000C in
vacuo. Bombarding the Ge targets gave rize to an ad,'..'tional
conductivity
pulse during each pulse of incident ions. The rise ind fall of
these con-
ductivity pulses (due to excitation of electron-holc pairs,
defects) is
exponential. The additional conductivity increases with
increasing energy
of the incident ions. However, there in a threshold energy of
300 - 400 ev
below which no additional conductivity is excited. The number
of electron-
hole pairs excited by one incident ion is a monotonic function
of the ion
energy E, amounting to about 900 - 1000 pairs at E - 10 kev.

TEXT: Ion induced electron and ion emission from LiF, NaF,
NaCl, KBr, C8C1
and silicon monocrystals was investigated. The crystals were
bombarded with
potassium ions of 40-7000 ev using the pulse method of G. M.
Batanov (FrT,

of 0.5-50 cps,

coefficients K of ion-induc6d ion emission of all
alkali-halides were
similar and similar,y dependent on the energy of primary
ions. The
coefficients K became largerwith increasing energies
(starting with
threshold energies of AOD-500 ev) of the primary ions and
reached saturation
values of 15~~ at E-1.5 kev at'most. The positive secondary
particles
consisted of knocked-out particles of the bombarded crystal
and reflected
ions of the primary beam. On increasinE the temperature from
room tempera-
ture to ANO-4000C, K+ and-K- remain practically unchanged.
The decrease of
j is attributed to the scattering of excited electrons from
phonons. The
temperature dependence of ? and the shifts in the spectra of
the secondary
electrons may be qualitatively explained by the enerC~r
looses of the
excited electrons. The coefficient i of silicon
monocr7;stals showed almost
a linear increase with Erowing energies of the bombarding
ions. This
increase was less at elevated temperatures, i.e. when the
specimens were

ABSTRACT It is usually said that the formatiou of calcium
hydrosilicate
on the occasion of the interaction between limestone with ailica
in the water medium by hardening of the binding oaloareous-sili-
cious building materials can only take place by hydrothermal
treatment in autoclayes at temperatures of an or.der of magnitude
of 1700.At normal temperatures this process is assumed not to ta-
ke place i.e.it is not expressod in a noticeable increase of
strength of the formedprpduotion. Some building productions,as
e.g. wall blocks,whioh are used more and more in low buildings,
do not need the strength obtainable in autoclayes. On the other
hand,the papers of the authors confirm the assumption that,be-
sides a hydration hardening of the caloareous-arenaoeous
bindin;,-
substanoe,the binding of the calcium hydroxide gradually devclopa
in the surface strata of the sand grains.The better this surface
Was developed and the more it was activated in the common break-
ing process,the greater is the quantity of limestone bound into
calcium hydrosilicate.By means of the radioactive isotope Ca45

to 2,9 m2/g) from a saturated solution was studied by the same
method.In the case of the introduction of fine-pulverized sand

curves show that independently of the disperAty of the sand,
the binding process always consists of two stages: 1)
chemisor-

the inter-
action, and 2) a very long period of chemical binding of CaO
at constant rates. The second processp evidently, is connected
with the formation of calcium hydrosilicate, the lattcr being

.the ion beam was produced (200 -- 300C). The results yielded non-
:monotonic variations of the secondary-emission coefficient and of the
positive and negative ion-ion emission-coefficients on the angle of
incidence. In view of the increasing dependence of the secondary
remission coefficient on the incident-ion energy, it is deduced that
at still higher energies the increase of the coefficient with the
angle will be steeper. This points out the advantage ol' using alkali-
halide compounds as cathodes for multipliers used to register ions
and neutral atomic particles. The positive ion-ion emission coeffi-
cient was found to be larger by a factor 4 -- 5 than the negative
coefficient. This is attributed to the fact that the reflected ions
of the primary beam contribute to the coefficient of positive ion-ion
emission. Authors thank M. -A. Yeremeyev and N. N. Petrov f or

The surfnce of the tar-

were incident ill tile

radiation-induced

zero to 3 x 1014
lions/ce' greitly reduced the radiation conductivity coefficient, it
did not affect the
position and relative height of this maximum. The number of pairs of
Frenkel defects
due to the ion bombardment was estimated by dividing the energy dose
by half the thresh
14 ions/cm2
iold energy for producing a pair of defects. For the 3 x 10 does this
cnlcu-
lation gave a defect density of 1.8 x 1016 cm-2, corresponding to
about 20 interstitial
germanium atoms in each channel in the (110)direction. The authors
argue that so high
in density of defects should alter the dependence of the radiation
conductivity coeffic-
lient on the incidence angle, and conclude that the defect density
was not actually so
high as calculated. Two possible reasons for the discrepancy are
suggested: either
there may have been a partial anneal of interstitinl atom - vacancy
pairs , or a par-
ticle moving In the LIQ direction in a germanium crystal may expend
considerably more
than half its energy in collisions in which the energy transfer is
below the threshold

ABSTRACT: In view of the lack of published data on ion sources
with beam currents on the order of 1 ampe're and above, the authors
report an investigation of a pulsed ion source of the dual plasma-
tron type, intended for pre-injection in a.,proton synchrotron. The
present dual-plasmatron output limit, approximately 530 milliamperes,
has been increased by modifyin the geometry in the ion selection

region and by operating at a forced discharge mode. In addition to
attaining large current it was necessary to impart to the beam
definite optical characteristics to match it to the optical system
of the acceleratoritube. The plasma generation principle is the
same
as proposed by Ardenne (Tabellen der Elektronenphysik,
Ionenphysik und
Uebermikroskopie,-Veb Deutsch. Verlag der Wissenschaften, Berlin,
1956). The pulsed current reaches 1.5 amperes, and a focused ion
,abeam with a current of approximately 170 milliamperes can be
obtained,
with a minimum diameter of 10 nun at 70 keV. Experiments show that
:if an immersion lens with larger potentials and compensatiop is
used, a much larger,ion current can be focused in this diameter.
present value of the beam current is limited by the limits of
plasma flow through the emission aperture in the selection region,
and by the slight divergence of the plasma as it diffuses through
a
small aperture. Further increase in the ion cu--rent can be
attained
,by increasing the.aource dimensions and source parameters. A con-
tinuous current of.1 ampere can be attained by Inproving the
cooling

of the anode and of the grid in the drawing electrode. Multi-jet
-plasma sources, which produce a dense plasma with large surface in
the selection region, will contribute to the production of larger
ion beams. The authors thank 1. P. Maly*shev for interestlin the
