The axial electric field of a positive column in a transverse magnetic field
Journal of Physics D: Applied Physics, 1977The axial electric field of a positive column with a transverse magnetic field of 0-300 G is given for neon at a gas pressure of 0.3-10.0 Torr with a discharge current of 40 mA. Measurements show that the axial electric field increases considerably with a transverse magnetic field in lower gas pressure.

Coulomb Clusters in Axial Magnetic Field
AIP Conference Proceedings, 2003The rotation of Coulomb clusters with different numbers of micron‐sized particles is observed in an inductively coupled dusty plasma in the presence of an axial magnetic field. The rotation is found to be dependent on the particle number and configuration.

Operating principle of an electron monochromator in an axial magnetic field
Journal of Mass Spectrometry, 2001AbstractElectron monochromators which are operated within an axial magnetic (guiding) field are especially suitable for the production of monochromatic electrons at low energies. Although in principle the technology of such devices has an appreciable historic background, we have discovered experimentally important new features, which cannot be ...

The vacuum arc in an axial magnetic field
Journal of Physics D: Applied Physics, 1975An experimental and theoretical study of the behaviour of a vacuum arc on Cu and Mo electrodes in an axial magnetic field at currents between 150 A and 16 kA has been carried out. The maximum magnetic field strength was 0.25 T. It was found that the influence of the magnetic field on both the high- and low-current arc was determined by the ratio ...

Effect of a transverse magnetic field on a toroidal discharge in a strong axial magnetic field
Journal of Nuclear Energy. Part C. Plasma Physics, Accelerators, Thermonuclear Research, 1965The effect of a transverse magnetic field on a toroidal discharge in a strong, axial magnetic field has been investigated. It was found that for a certain definite displacement of the plasma pinch by the 1/c(I × B⊥) force, the amplitude of the fluctuations on oscillograms displaying the electrical characteristics of the discharge was a minimum and the ...

Axial Magnetic Fields in Relativistic Self-Focusing Channels
Physical Review Letters, 2002Based on an improved cavitation model for the electron dynamics, an exact analysis is presented of the generation of axial magnetic fields in the relativistic self-focusing channels produced by circularly polarized light in plasmas. Two kinds of waveguiding structures are considered: single-channel waveguides and plasma filaments surrounded by a light ...

2018 IEEE International Conference on Plasma Science (ICOPS), 2018
We investigate fundamental physics involved in plasma implosion with pre-embedded magnetic field. Reported are the first time spectroscopic measurements of the evolution of the azimuthal magnetic field distribution; the configuration used is magnetized z-pinch plasma.

Computing the field in permanent-magnet axial-field motors
IEEE Transactions on Magnetics, 1994A closed-form expression is presented for computing the axial field in the coil region of permanent-magnet axial-field motors. This expression, which is based on a two-dimensional approximation of the motor geometry, takes into account the finite slope of the demagnetization curve of the permanent-magnet. It can be used to perform parametric studies of

Mercury arc plasma in an axial magnetic field
International Journal of Electronics, 1980The electron temperature of a mercury are plasma (are current 2·25 A and 2·5 A) has been measured spectroscopically in an axial magnetic field varying from zero to 1050 gauss. It has been noted that the electron temperature decreases with the increase of the magnetic field.

The magnetic potential of axially symmetric fields
Nuclear Instruments and Methods, 1965Abstract A general expression for the magnetic potential of axially symmetric fields is carried out: the results are rigorously correct, if no currents are present. The problem is solved by a harmonical function, whose axial derivative fits the given field form in the median plane: this coincidence is imposed up to second order terms.
