Abstract
The structure of a magnetized, collisionless crossed-field coaxial Hall dis charge is investigated using low-impedance, negatively biased Langmuir prob es. We present images depicting frequency-position renderings and cross-cor relation plots, which identify coherent and random fluctuations in plasma d ensity. These fluctuations are found to depend on the discharge operating c onditions, and are believed to greatly affect cross-field electron transpor t.
