\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 about x 63.5  Gauss along the length axis.  Measurements were taken using 5 different frequencies of the emitter starting at 20Mhz to 120Mhz in 20Mhz steps.  The electric field is measured using an electric dipole reciever probe. In this experiment it will be three dipole reciever probes as shown below [1].
