  We present a broadly applicable in situ method for profiling ion beams using
electrostatic deflectors and a Faraday cup. By deconvolving the detector
geometry from the resulting current profiles, spatially resolved absolute
current density profiles are obtained. We demonstrate this method's efficacy
with low-density highly charged ion beams (specifically, Ne$^{8+}$). Details on
experimental design are provided as well as the link to the deconvolution
routine on Github.
