\section{Experimental Setup}  The plasma was created by an inductively coupled RF source operating at a power of 215 W with x\textsuperscript{−3} torr Helium as the working gas.A voltage sweep was put across a langmuir probe 70 cm from the RF source 10 ms into the afterglow. A magnetic field was applied to the device through the use of two sets of four coaxial magnets created using 59.0 A and 24.5 A currents laid out around the device and resulting in a radially symmetric magnetic field through the device averaging to 63.5 Gauss along the axis.  Measurements Waves  were taken generated in the plasma  using a waveform generating antenna, in  5 different frequencies ofthe emitter starting at  20Mhz to 120Mhz in 20Mhz steps. The electric field is measured using an An  electric dipole reciever probe. In probe was used to measure the electric field in  this experiment it will be three dipole reciever probes as shown below [1]. experiment. Measurements for the 20Mhz data run began at -5 cm(\bold{how do i say this?} with 5 measurents taken in the z direction in 2 cm steps.
