Deflected Beam Method for Absolute Current Density Determination
arXiv:2303.00921
Abstract
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). Details on experimental design are provided as well as the link to the deconvolution routine on Github.
