Funding: National Science Foundation Grant 1632761 Instabilities in magnetized plasmas, such as the cyclotron instabilities identified at JYFL*, can cause fast variations of the extracted ECRIS beams. In order to understand the effect of the radial component and longitudinal gradient of the magnetic field on plasma stability a series of measurements has taken place using the Superconducting Source for Ions (SuSI) at the National Superconducting Cyclotron Laboratory (NSCL). We present here the results from investigations into the instability characteristics of the beam current from SuSI at 18 GHz by varying longitudinal and radial magnetic field profiles, injected microwave power, and bias disk voltage. Our investigation shows multiple regions of beam variation within the magnetic field v.s. power phase space with multiple distinct modes of variance. *O. Tarvainen, et al., Plasma Sources Sci.
