PARALLEL ELECTRIC FIELD ON AURORAL MAGNETIC FIELD LINES
The interaction of Birkeland (magnetic-field-aligned) current carriers and the Earth's magnetic field results in electrostatic potential drops along magnetic field lines. The statistical distributions of the field-aligned potential difference (phi)(,(PARLL)) were determined from the energy spectra …

Oscillating Field Current Drive in the Reversed Field Pinch
Oscillating Field Current Drive (OFCD) was originally proposed as a means of maintaining a quasi steady-state plasma current in a RFP without building up the magnetizing flux threading the central hole of the torus. The MHD dynamics of OFCD is analyzed using a combination of a 1-D transport code, a …

Parallel Plasma Field Directed Sputter Sharpening of Field Emitters
Many of the current methods to sharpen field emitters are time consuming and can only process one field emitter at a time. In this thesis, a method is proposed to parallel process multiple field emitters using a DC glow discharge plasma as the ion source in conjunction with field directed sputter …

Internal-External Control of Reinforcement Versus Field Dependence-Field Independence
… the concepts of internal-external control and field dependence-field independence as two basically separate dimensions. However, in the area of personality, the two concepts may be related to a considerable degree. A review of the literature suggests that many of the same personality …

The Earth's Magnetic Field
The Earth's magnetic field is essential for life on Earth, as we know it, to exist. It forms a magnetic shield around the planet, protecting it from high energy particles and radiation from the Sun, which can cause damage to life, power systems, orbiting satellites, astronauts and spacecrafts. This …
