TL;DR: In this paper , the authors describe the evolution of the beam profile at today's operational beam intensities of 35 mA for various ratios of volume and surface ion origin, showing that the presence of surface produced ions occurring on a conical plane is characterized by the electron to ion ratio and by measurement of the Cs-coverage of the molybdenum plasma electrode down to a fraction of a monolayer.
