Abstract
In a toroidal device we created plasma using a microwave generator. We took measurements using Langmuir probes to determine the temperature and density of the plasma at different combinations of magnetic field and fill pressure. Here we consider the general characteristics of plasma in terms of temperature and density profiles at about .9 milliseconds after the plasma was created. We have focused on the data taken by a probe close to where the plasma was generated. We will also consider some of the future work that would need to be done to further understand plasmas of this nature.
