Abstract
In this thesis work, I designed, fabricated, and calibrated, a radio-frequency magnetic probe, subsequently used to measure magnetic turbulance in the reconnecting plasmas of the Versatile Toroidal Facility (VTF). Reconnecting Hydrogen plasmas were created, and magnetic fluctuations in all three artesian directions were measured in the 1-101)MHz range. A preliminary hodogram analysis of the fluctuation spectra found the propagation direction of low-frequency (1-5MHz) electromagnetic waves to be parallel to the direction of the plasma current, while high-frequency waves had a random distribution of propagation directions.
