Abstract :
Summary form only given. Magnetic loop probes with areas ranging from 0.2 to 0.9 cm2 were used to observe azimuthal, radial, and axial magnetic fields versus time at 28 locations in compact toroid formation discharges. The probes were enclosed in 6-mm-outer-diameter, 4-mm-inner-diameter glass tubes which were inserted through the 90-cm-diameter inner (electrically hot) electrode. Probe signals were sent to an array of Tektronix 7903 oscilloscopes via fiber optic links. Typical field values ranged from 0.1 to 2 T. Typical discharge currents had a 3-μs risetime. Comparison with 2D-MHD predictions was made, and good agreement was shown
