Emission Current Dependence in the Time and Angle Noise Spectra of Gallium Liquid Metal Ion Sources

The total power in the statistical fluctuations is observed to be roughly proportional to the axial current density from the source. There is no indication in the 10-500 Mhz range reported here of any resonant behavior in the emission correlations, such as have been reported by Bahasadri, et al at much lower frequencies.
