TITLE: Influence of the Cathode Zone on the Dynamic Properties
of a Glow Discharge in Hydrogen (Vliv katodove' oblasti

PERIODICAL: 6eskoslovensky dasopis pro Fysiku, 1958, fir 5,
pp 526-533 + 1 plate (Czech)
ABSTRACT: To elucidate the influence of the cathode zone on the
dynamic properties of a discharge the authors carried-out
a number of measurements. In the first part of the paper
the results are reported; in the second part the authors
attempt a qualitative interpretation of the measured
relations. The measurements were carried out using the
same technique and the same apparatus as was done in
measurements reported in earlier woxk (Ref 2). The
discharge tube was connected to a stabilised source of
2.5 kV d.c. which was bridged by agi e capacitance;
between the cathode of the dischar Md the grounded
negative pole of the source a pentode was connected for
the purpose of regulating and stabilising the discharge
current. Parallel to the pentode a capacitor of
Card 1/5 variable capacitance C x was connected. The results

measured for various capacitance values have enabled
evaluating the influence of the parasitic capacitance of
the cathode end of the discharge relative to ground.
Near to the cathode a metal rinG was fixed on the external
side of the discharge tube to which very short high
voltage pulses were fed. Each such pulse brought the
discharge into a non-steady state. The establishment of
a steady state manifested itself by changes in the
intensity of -the li6ht emanating from the discharge and
changes in -the voltage of the cathode of the discharge
relative to ground. The characteristio3of both these
magnitudes was observed on the screen of a pulse-cathode
oscillograph; typical oscillo6rams of -the cathode voltage
recorded by this method are reproduced in Fig.1 (plate
p 632b). In Fig.2 the dependence is graphed ofthe
oso-illation frequency on the pressure and on the
capacitance of the external condenser C x (I = 0.20 aA,
length of discharge gap 48 cm). In Fig.3 the dependence

discharge length of 68.5 cm. In measuring the dynamic
properties of the glow discharge in spectrally pure
hydrogen it was found that the cathode region does influence
the behaviour of the discharge in the unstable state. The
results of these measurements are given and also their
phenomenological interpretation, which is based on the
equivalent circuit of the discharge, Fig.4. The relations
derived in the paper permit calculating the magnitudes
of all the capacitances and inductances in the equivalent
circuit from measured results of the dependence of the
oscillation frequency on the capacitance of the external
condenser C . If the results of measurements of the
dependence ~f the oscillation frequency on the length of
the discharge path is known, it is in princiPle possible
to calculate also the magnitude of the inductance L s and
of the capacitance C S per 1 cm of the length of
the positive column. It is practically not possible to
measure accurately all these relations over a sufficiently
wide range because a change in one of the discharge
Card 3/5 Parameters brings about a change of the frequency and

CZ/37-58-5-3/19

Discharge in Hydrogen
damping of the oscillations and the frequency values
determined in the case of high damping are very inaccurate.
For the time being it is not possible to go beyond
determining the order of magnitude of the reactive
parameters of the discharge. The results described in
the paper show that in the case of a non-steady state glow
discharge, the influence of the cathode region on the
dynamic properties of the dischar~,;e can be appreciable.
Thereby, the dynamic properties of the cathode region are
U
of such a type that they are supplementary to similar
properties of the positive column and thus form a
resonance circuit. Thereby, the possibilit-
y is provided
of the generation of low frequency oscillations in the
discharge even if the external discharge circuit does not
contain any reactive elements at all. Ackmowledgments
are made to Dr. L. Peka'rek for his advice and assistance

TOCT: The hollow cathode of an experimental discharge tube consisted of
two parallel nickel plates. The tube was filled with neon up to 2.7 mm Hg. When
a photomultiplier was used, the change of light intensity in -dime was recorded
at different distances between the cathode plates and with constant discharge
current. The effect of the hollow cathode, while neither producing intensified
striation in the positive column nor acting upon other striation parameters, wan
found to impair the feedback between the anode and cathode, the magnitude of
which in most cases determines the production of self-excited moving striations.

TE-=I: A mechanism of the lamination of a positive d-c column is suggested
and physically interpreted on the basis of a greatly simplified system of equa-
tions, whose solution describes the production of a periodic structure of the
plasma of a positive column after an aperiodic disturbance. Only three principal
Xphysical phenomena, taking place in the plasma of any d-c discharge, were con-
sidered: 1) dependence of ionization on the electron temperature, and, come-*
quently, on the electric field; 2) formation of space charges as the result of
different ion and electron diffusion rates; 3) production of additional elec-
'uric fields due to the appearance of space charges. The foregoing processes as
a whole give rise to a characteristic circuit, developing in time and space, and,

tions. In accordance with experiments, this structure arises only between the
auiode and the seat of local disturbmee in the plasma. There are 23 references.

TITLE: Analogy between a stratified plasma wave and the waves
on the surface of water
PERIODICAL: 6e:31-1-oslovanslky casopis pro fy siku, no. 5-6, 1962,
546 - 552
T EXT The process of wave-forination on a smooth water surface
is well known, whoreas a similar process of the appearance of '
triobilo layers, kno;,rn as "stratification'waves", in a gas discharge
is a comparatively unknown phenomenon. Such waves in gas dis-
charges can be produc od, for instanco, by applying an iTxx-iodic %,nltage
pillse to till electrode situated in ttle discharge tube. This
pulse produces an initial stratum which rapidly disappears but
results in the formation of a similar stratum at a certain distance
in the direction of the anode. In turn, after a delay, another
stratimi is produced and so on; a set of strata which moves towards
the anode is observed only after several ms,-whereas the individual
strata move in the opposite direction. The thenry of gravitation
waves on the surface of water can be approximately described by the

TITLE~ A novelty, Wireless microphone
PERIODICAL.: Sd~lovaci' technika, no. 2. 1962, 70
TEXT;. The device described is in effect a frequency-modulated
miniature transmitter. A detailed circuit diagram of the system
is given in Fig. I., In this, a transistor T 1 operates as
an oscillator. The transistor is OC170 and is specially chosen
in order to be capable of operating at 100 mc/s. The transistor
operates as a common-base oscillator with the tuned circuit in
the collector, the feedback being taken from a tapping on the
tuning coil through the capacitor C 1 to the emitter. The
oscillator is followed by a high-frequency amplifier stage based
on the transistor T. , which is coupled to the oscillator by the
coil L 2 . The collector of T2 contains the tuned circuit
L3-C 6 'which is coupled to the antenna. The signal from a

A novelty E192/E382
dynamic microphone is amplified by a single-stage audio-amplifier
based on T 3 ' The amplified audio-signal is applied to the base
of T I through the coupling condenser C 7 ' The low frequency
thus changes the operating voltage between the collector and the
base of T I ' This results in the modulation of the collector-
base :apacitance of T, , which is connected in parallel with
the tuned circuit. In this way, the oscillator undergoes
frequency-modulation. The system is fed from a 13.5 V battery
and produces an output of 20 mW in the antenna. The frequency-
modulati.on deviation is 100 kc/s and the bandwidth of the audio-
channel extends from 20 c.p.s. to 20 kc/s (at 30 db)~ The
microphone can be used at distances of 50 - 100 m.
There are 2 f-igures.

TITLEt Changes in mechanical properties of cord through the effe~-t

PERIODICALs Plaste und Kautschuk, v. 8, no. 2, 1961, 66 - 69
TEM Plastics and textiles suffer a change through radioactive radiation.
Since automobile tires can now also be vulcanized by means of ionizing
radiation, the authors studied resulting deteriorationn of mechanical
properties of tire cord (strength ' elasticity). The following cord types
were irradiated in air (from 2 - 245-1o5 rep h) with various doses of 6-- ~'/
radiation (from 6o CO) in the range of from 104 to 10 8 rep., terylene cord
(from Great Britain), dederon card (Eastern Germany), caprone cordo
silon cord, nylon cord (Switzerland), Rudnik viscose cord (Czecho-
slovakia)p Cordenka super viscose cord (Netherlands), and cotton cord frim
Egyptian cotton. Diagrams show the measured resultsi the follow4ng losses

in strength occur at a dose of 3-107 rep; polyaimide --Ords 7(Y/o, cotton
cords 406, viscose cords 30%, terylone 6;j'. Cotton- and viscose cords
were almost entirely destroyed at doses above 10 b rep, and a loss In
strength of 60% occurred in terylene cord. The decrease in mechanical
properties with an increase in the radiation dose proceeded for the
individual tire cords as followss cotton cordi continuous decreasel
vicose cord: Rudnik: a similar course, the elasticity decrease amounts
to 45% at 3-1o7 rep; Cordenkas after an initially low decrease, the
strength- and elasticity drop increases, at 3-1o7 rep, the elasticity dToV
amounts to 47%; polyamide cords: silon, dederon, caprono ` nylonj
strength does not change in the range of small doses up to 4-105 TeP; a
steep drop takes place then, but from 2-107 rep, the drop becomes small
again; terylene cords strength hardly changes up to a dose of 107 rep,
and then decreases slowly. A 50% decrease in strength occurs at t-he fol-
lowing doses: terylene 1-5-108 rep, Rudnik 4-7-107 rep, Cordenka 3.6-10 7r~-D,
cotton 2.6-107 rep, dederon 1-4010 7 rep, nylon 1.1-107 rep. Silon
