Results are given of experiments with plasma discharges at high current den-
sities. Intense radial EM radiation was detected which was coherent and
close to Langmuir frequency. Test apparatus included an alundum discharge
tube, 10 cm irf didineter'and 25 cm in length, charged with H2; aluminum elec-
trodes, connected by a 15-~Lf capacitor bank charged to 30-40 kv and yielding
a discharge current of about 100 kamp; an axial magnetic field variable from
0 to 10 kgs. Efforts to insure repeatability indluded tho use of metal vacuum
seals and a titanium pump, the baking pf t4e apparatus at 300*C, and pre-
ionization of the gas mixture prior to discharging. Electric field gradients of
3.00a-500 v/cm gave a high "runaway" electron condition in the discharge beam.

COHERP-M EM RADIATION [Contldl S/089/63/014/004/001/019
This current was measured by means of a Faraday cell and a Rogovsky belt,
both located at one electrQde. A typical test result at a 6-kgs field strength
and a 3-4- psec plasma life showed that coherent EM radiation received by a
horn antenna through the tube wall and d4~tected over the 8-14. 4-mm wavelength
region was as -much as 107 times more intense than thermal radiation from a
plasma of 10-ev electron temperature, and was constant along the column.
Coherence was detected by two probe antennas placed U mm apart in the column
and connected to an 8-mm interferometor. Variation of the magnetic field
from. 0 to 8 kgs had no effect on observed radiation. Variation of other param-
et'ers revedled a sharply critical value of runaway electron current, below
which radiation is absent and above which it rises rapidly in intensity accom-
panied by a dip in runaway current. This verified a casual relationship be-
tween the two. The relation of radiation intensity to initial gas pressures and
to radial distance from the plasma column are also discussed. [SH ]

ABSTRAM Donse (up to 2 x 10 cm-.) plasmas were produced in a 12.5 cm diameter,

up to 2.5 kOe was provided by a suitable winding. The experiments are preliminary
to a projected investigation of plasma heating by ion cyclotron waves. 7be plasm

so determined were in agreement with the values obtained from microwave reflection.
Owing to the rectifying action of the plasma, the electrod4a-:became negatively charged_
to a potential of several kilovolts; t1his gave rise to an oscillatory motion of the
electrons near the axisof the chamber between the electrodos,as a result of which
the dense plasmas were produced. The dense plasma was confined to a 2 cm diameter
region about the axis; at 3 cm from tho axis the plasma density was less by an order
of magnitude. The plasma density did not depend strongly on thq magnetic field
strenxth. The maximum observed plasmadensity was 2 x 1014 cm-j at a gas pressure of

ABSTRACT: Theheating by high frequency generators and the breakup of pta'sma is stud-
ied by making use of the dependence of the plasma diamagnetism on the perpendicular
component of particle energy. The method of measuring the diamagnetism consists of de7
termining the magnetic field in the plasma and comparing it with the external field. I
The measurements were made on an experimental apparatus which used either a strong ion!
cyclotron wave or fast magnetosonic wave for plasma heating. The results showing the
ion temperature as a function of a ratio of the external magnetic field to the plasma
field (at which the gyrofrequency is 10 MHz) indicate the maximum temperature of 10

The expected cooling time of the ions was observed to he reduced by a
factor of ten down to 10 jisec owing to energy transfer to colder electrons and to

ABSTRACT- This work reports on three experimental studies of electric fields in plas-
ma. Electric fields arising due to polarization in plasma in 1) curved magnetic fields
with varying radii of curvature, 2) in a toroidal field where two plasmoids collide
and 3) in a case where a plasmoid moves along the toroidal field, are studied. The
measurements were performed with two probes, one near the vessel wall and the other
located at a given point in the plasma. The plasma was generated in a conical pinch
gun and injected into the working region. The experiments show that polarIzation
fields consist of the components along the toroid's major and minor radii and along
the toroidal axis. Initially, the latter two components dominate in the main part of
the plasmoid; subsequently, only the axial component is dominant. Plasma density was

ABSTRACT: An attempt to develop a plasma source free of impurities by the use of a
coaxial gun in a longitudinal magnetic field is discussed. The plasma gun and its
operation is described, its energy source is a battery of condensers (1000 pf) working
at 5 kv, the working gas is hydrogen injected by a fast-acting valve. When the gun
is operated in the magnetic field, the discharge current plate appears. This, togeth-
er with the observation of the plasma ejection velocity, indicates plasma drift typic-
al of crossed electric and magnetic fields. High speed photography reveals that the
plasma generated when the magnetic field is applied is much more uniform than in the
absence of the field. Spectroscopic analysis shows that the magnetic field inhibits
very strongly the appearance of electrode material impurities found in discharges
without the external field. It is planned to overcome the insufficient ionization andl

the conditions for producing the waves do not deteriorate with Increasing plasma size

frequencies if it is desired to heat both the ion and the electron components of the
plasma. Regular oscillations at frequencies of the order of 20 1d1z of the intensities
of spectrum lines were observed at magnetic field strengths close to the proton cyclo-
tron resonance. These oscillations appeared when waves were being excited in the
plasma and were due to eccentric rotation of the plasma filament as a whole with
respect to the axis of the chambert as was confirmed by longitudinal observation with
two photomultipliers mounted 3 cm from the axis. The ion temperatures were determined
from the Doppler broadening of spectrum lines. The temperature of the additional gas
(helium or argon) increased sharply as the strength of the magnetic field app~mached
the proton cyclotron resonance value. Argon temperatures no high as 250 eV were ob-
served. Temperatures of various impurity Ions were elso measured; these temperatures
were independent of the mass of the impurity ion. The width of H13 interpreted as
Doppler broadening, indicated a much lower temperature for hydrageniatoms than for the
various ions. This is ascribed to the short life of a hydrogen atR6 in the plasma.The
temperature of the plasma decreased rapidly with incresaing distance from the axis,
being down by a factor of 5 at 4 cm from the axis. The ion: temperature increased
rapidly with increasing bigln-f requency power, and such higher tempelvatures could appar-
utly be achieved by increasing the high-frequency power and the magnetic field
trength. It in concluded,that a dense plasma.containing two kinds of Ions can be

it remained for 10--20 psec,. although a rather large electric field was applied to the,
plasma. In all the intervals of the investigated neutral gas pressure and electric
and magnetic field intensities the discharge was accompanied by microwave emission
from the plasma at wavelengths X - 2-4 cm. In stronger electric fields a broad spec-

maximum radiated power in the 3.2--15 cm interval. In electric fields stronger than
critical, the plasma emits also intense x-rays,f`iom which it is deduced that the pW-

the experiments were collective excitations by ion cyclotron and fast magnetosonic
waves. The characteristic waves in the plasma were excited by the spatially periodid.1
electromagnetic fields with 10 14Hz frequency. The generator power used was at the
300 kw level. The particle energy and composition was measured by the electrostatic
aralyzer and multigrid probes. The plasma temperature was determined by spectroscopic:
methods. Plasma density was determined by a microwave interferometer. It was found
that three types of ions flowed out, namely, H1, H2, H3, all of which had the same

energy even though the resonant acceleration,condition is satisfied for H, only. The
ion temperature of 2 kev was reached, while the electron energy was only 30 ev. -this
also indicates the presence of three types of ions. In magnetosonic wave heating,
both ions and electrons were found to reach a temperature of 150 ev. The various mea-1

TOPIC TAGS: plasma gun, hydrogen plasiwt, contamination, longitudinal magnetic field,
ABSTRACT: In an effort to improve the purity and the uniformity with regard to
velocity, density, and total number of particles of the plasma bursts from a coaxial
plasma gun~lthe.authors investigated the influence of a longitudinal magnetic field
on the performance of the gun. It was anticipated that the rotation of the plasma
within the gun,,due to the Lorentz force on the radial current in the longitudinal
magnetic field, would improve the azimuthal uniformity th current sheet. The dia-
0 Zhe 70 cm long coaxia
meters of the inner and outer stainless steel electrodelot 1
gun were 3 and 7 cm, respectively. The gas (0.1 cie of ydrogen) was admitted through
six openings in the inner electrode near its center, and the gun was fired by the 20
kV discharge of a 12 microfarad capacitor. The plasma gun was located in the uniform
portion of the field of a 1.4 m long solenoid. The magnetic field rose to its
maximum strength of up to 8 k0e.in 28 millisec and subsequently decayed exponentially
with a time constant of 72 millisec. The processes taking place within the plasma gun

L 41007-66
ACC NRi AP6018729
were investigated with the aid of a magnetic probe and by recording the discharge
current, and the plasmas ejected from the gun were investigated with an external
magnetic probe, a spectrograph, a photomultiplier, a monochrometer with the aid of a
which the intensities of different spectrum lines were displayed on an oscillograph,
and a thermal probe. The rather involved processes that took place within tho gun are
discussed at some length. The rotation of the plasma gave rise to a magnetic trap
within which a considerable portion of the gas was confined. Two plasma bursts were
usually produced, but Vnder some conditions it was possible to obtain only one burst
containing some 2 x 10,16 particles at a density of 2.4 x 1013 cm-3 and-moving with a
velocity of 3 x 107 em/sec. The purity 0 the plasma bursts increased with increasing
longitudinal magnetic field strength; at a magnetic field strength of 6.4 We there
were no lines due to electrode materials in the spectrum, and the lines due to carbon,
oxygen, and nitrogen were considerably weaker than in the spectra of plasmas produced
without the magnetic field. It is concluded that with the aid of a longitudinal
magnetic field one can obtain from a coaxial plasma gun pure high energy plasmas free
of slow and contaminated tails, but at the cost of inefficient use of the energy stored
in the capacitor bank. The authors thank O.M.Shvets, and Ya.F.Volkov for discussions

diagnostics consist of: 1) voltage monitoring across the plasma column, which deter-
mines the coupling between the generator and the plasma load; 2) spectral measure-
ments of plasma ions and impurity lines,, giving the density and temperature of the
ions- and 3) magnetic probe to determine the field distributions. A plasma density of!

used, an ion temperature of 2-1060K was reached. Since the ion temperature depends
strongly on the applied voltage, it is concluded that higher voltage would result in
hotter plasma. It was also shown that a mixture of two different ionic species can
be effectively heated; the energy transfer mechanism, however, must be further inves-

ABSTRACT: The beating and gontainmgn nf.pLasma in a strong magnetic field in the
presence of instabilities caused by "run-away" ere-c-trons is investigated. The experl-I
ment consists of a 100 ka linear discharge in hydrogen, characterized by the absence 1
of gross hydrodynamic instabilities. The "run-away" current was monitored to study
the onset of two-stream instability and the resultant thermalization of the plasma.
In the absence of collisions the anomalous diffusion observed is attributed to an In-
crease in the kinetic pressure of electrons in the center of the discharge. This ef-
fect was used to estimate the electron temperature from the time of arrival of the ex-
panding plasma at the tube wall. The heating time, measured by observation of the
emitted x-radiation and intense microwave bursts, is much shorter than that which can

be eyplained by collisional heating. The very high final temperature of the electroi
(2 kev) and short heating time correspond to the postulated collective process of
heating by a two-stream instability. (hAg. art. has: 4 figures.

-field configuration recorded with simultaneous injection of plasmas from opposite

.three components'Vzq VR# and Vr: VZ Is parallel to the axis of the'torus, VR is in
the direction of the large radius of.the torus, and Vr is in the plane of Vz and
Vit and is directed away from the axis; of the drift tube(along the small radius of
the'torus)* it weis found that Vz cheinges sign when the direction of the magnetic
field is reversed but not when the direction of motion of the plasma through the
U-sbaped drift tube is reversed without reversing the field. When the direction
of motion of the plasma through the ")'-shaped drift tube was reversed, however, the
Vz e6mponent of the polarization measured in the straight section joining the two
half-tori changes sign. When two oppositely moving plasmas collided in the center
of the U-shaped drift tube the value of V. was approximately the same as when only
one plasma was present, When two oppositely moving plasmas collided in the strai-
ght section joining the two half-tori of the S baped drift tuber the Vz polariza- i
tion components of the two plasmas canceled each other and only Vr was measured*

ABSTRACT: This paper reports a continuation of work by some of the present authors
and others (ZhTJ 35,62,1965 Zziee Abstract AP500323g) concerning the confinement of
1 plasma injected into a cusp magnetic field. The present work was performed without
the magnetic field, and was undertakiia to Investigate the processes taking place "
colliding plasma bursts. Plasma bursts were injected from one or more of four coni-;
cal plasma guns equally disposed about the periphery of a 20 on diameter stainless
steel tube, and the spectra were observed in both the longitudinal and tranaTerst
directions. The ti -integrated spectrum was recorded photographically In the ransal
from 2000 to WOO r anti the time dependence of the intensity of certain limes was i
dettrained with a ;~otoelsctrlc Instrument. The plisms bursts had a maxi=m density-

fast component of a bursts was,1.4 x 107 cm/goo; this wan followed by a mlo-wer
Itall". The collision of two plaarj& burats led to an increase In the intensity of
all spectrum lines and the appearance of lines that were not observed in single 1
bursts. Velocity measurements performed with the photoelebtric instrument using the,
VP 4861, C 1 4371 and C 11 4267 lines showed that both the carbon Ions and the by-
drogon atoms moved more rapidly than thocarbon atoms. The presence of excited ions
in the plasma burst at a considerable distance from the source in discussed, and it!
is suggested that these are continually formed by a charge exchange mechanism. Thai
Ion temperature was determined from the Doppler broadening of the C 11 4267 line.
Collision of the plasma bursts was found to be accompanied by an increase of the I
ion temperature. After brief discussion it is concluded that the strong interaction
between plasma bursts observed in this and the previous work can be accounted for
by Coulomb Interaction. "In conclusioni, the authors expriss their gratitude to lo,

level of the high-frequency'power on the plasma heating in the ion
e region, an experiment was performed with a setup de-
f scribed in detail elsewhere (ZhTF v. 32, No. 5, 1962). The results
of the tests indicate that there exist two distinctly different
modes of plasma behavior, one in which the plasma exists for a reld-
tively long time, and one in which the plasma begins to decay even
before the termination of the high-frequency power.pulse. A radical
Idecrease in the lifetime of the plasma occurs at a definite critical
,power level supplied to the plasma, and the smaller the pressure the
~smaller the critical power. The critical power depends on the
icleanliness of the system and increases for a poorly preconditioned
isystem. This dependence on the pressure and on the purity of the
system suggests that the observed instability is due to the appear-
iance of ion currents with large directional velocities, At the

the authors investigated the injection of plasma through the annular

periphery. The report describes the first experiments in which in-

field, as well as in the gap existing during a certain time ("mag-
netic valve"). To simplify the initial experiments, the injection
gap was produced by a constant field, with the coils connected to
buck each. other. A 20-cm diameter and 180-cm long cylindrical stain-
less steel vacuum chamber was used. Eight conical plasma guns were
distributed uniformly around the periphery of the chamber in the mag-
netic gap plane. The synchronization circuit permitted simultaneous
swit6hing of all eight guns or a fraction 9f them. The plasmoids
injected by each gun had a density 2 x 1014 cm73 and a velocity of
3 x 104 m/sec. The working va-cuum. was 6.6 x 10-4 n/m2. The maximum
magnetic field intensity, equal to 2 x 105 A/m, was located 40 cm
away from the magnetic gap. The experimentshave shown that a plasma
injected into a gap between opposing magnetic fields moves subse-

between the opposing plasma streams, even in the absence of external
magnetic fields. The nature of this interaction, and the time of
confinement of the plasma in the trap when such an injection method
is used, will be investigated in the future. Orig. art. has: 9

this power. It is possible to obtain in such a chamber a rotating
plasma in crossed electric and magnetic fields, with high density,
high degree of ionization, sufficiently lone confinement time, but

found that much more power can be fed to the plasma without-a capaci-
tor. The experiments have shown that high-power high-frequency
generators can be used to produce a dense plasma in a metal chamber
at relatively low voltages. The densities attained were 1.2 x 108

tudinal oscillations, m.e -- electron mass, M ion mass) excited
in a plasma by a beam of "runaway electrons," was investigated.
The experiments were carried out in a straight tube (alundum, 10
cm dia, 25 cm long) usually filled with hydrogen at 1.3 n/m2, tl~rough
which a 15 F capacitor bank was discharged from 30--40 kV. Prelim-
inary experiments with the setup were reported elsewhere (ZhTF, v.
30, 1057, 1961). in the present experiment the formation of the cur-
rent of runaway electrons was investigated along with its correla-
tion with the electromagnetic radiation of the plasma; some charac-
teristics of this radiation were also investigated. The measure-
ments have shown that an electron current, with energy equal to the
maximum energy, constituted a small fraction of the total runaway
electron current, the bulk of the current being due to electrons
with energy somewhat higher than thermal but much lower than maximal.'
*Part of the runaway electron beam goes to the development of electro-
static instabilities in the discharge, which give rise to the occur-
rence of the electromagnetic radiation. The radiation was found to
Card 2/6

ACCESSION NR: AT4036051
be coherent in the entire range of investigated initial gas pres-
sures, with an intensity which is constant practically along the
entire discharge length. The frequency of the electromagnetic radi-
ation was found to be close to the plasma frequency and the power to
f th
exceed appreciably the power of - ermal radiation from the plasma.
The transformation of the longitudinal electrostatic oscillations
into transverse electromagnetic waves can be attributed to-the non-
linearity.of the oscillations in the plasma due to the large ampli-
tude, and also to boundary effects on the surface of the plasma pinch.

the inner circumference of the central part of the chamber. The
discharge period was 6 uacc. The plasma consisted of fast and slow

_'-ABSTRACT: The injection of plasma into an opposed field magnetic trap of the type
discussed by John E. Oshor (Phys.Flov.Latters,8,305,1962) and others was investigat-,
a
ed experimentally. The trap was formed in a 70 cm long 30 cm diameter vacuum ch m-
ber by the discharge of a bank of capacitors through two windings, each about one
;half of the chamber. The rise time of the magnetic field was 4.4 millisec and the
subsequent decay time was 16 millisec. This behavior was achieved with the aid of a
$shunt circuit. The maximum magnetic field was 5 kOe in the mirror regions and 4.2
k0e~-in the gap. The plasma was injected axially through the magnetic mirror at the;
time of maximum field strength by an ordinarycoaxial plasma gun. The gun was opera-
ted in two different modese In one mode ("short delay) the plasma was 'emitted In

several bL 'having different velocities. The velocity of the most rapid of thos
,J`
bursts was 8.8 x 107 cm/sec, corresponding to a hydrogen ion energy of 3.9 kev. Them
X-rays produced in the apparatus were recorded with a cesium iodide crystal, shield-
ed from light by aluminum foil and located in the magnetic gap. A short burst of
x-rays was always observed at the moment of injection. When the plasma gun was ope-,.,~
rated in the short delay" mode there was observed, in addition to this, an intense'
emission of x-rays beginning 840 microsec after injection, reaching its peak at
about 1500 microsec, and decaying with a 3 millisec time constant,. The spatial and
energy distributions of these x-rays were investigated with a photographic film and:
a stop absorber. The x-rays were found to originate within the magnetic gap. The
mean one
rgy of the x-rays was 3.8 keV, corresponding to the energy of the injected
hydrogen ions. It is concluded that the x-rays were produced by impact with the
',wall of the chamber of charged particles that were imprisoned for a time an
d then
through the magnetic gap. Orig.art.has: 3 figures#
