MAGNETIC FIELD MEASUREMENTS IN A CURVED THETA PINCH WITH LIMITERS

摘要

The Curved Theta Pinch Experiment, which uses an oscillating axial current to establish a toroidal equilibrium, has been modified by introducing quartz limiters at the ends of the discharge tube. This report describes recent mea¬surements on the new version of the device. In contrast to previous experiments, we observe that the oscillating axial current flows mainly through the dense plasma column.
