Ion energy loss spectroscopy is suggested to determine the shape of the (latent, etched and filled) ion tracks in polymers using ion probes of various beam sizes. For a milli-probe, it can be considered as a one-dimensional tomography of many identical (rotationally symmetric) objects. For a micro-probe, the technique can be understood as a micro-tomography of the single ion track. In both cases, the ion energy loss spectroscopy requires monoenergetic ions with a low intensity (<10(-3) s(-1)) and a well defined angular beam set-up. Here we present a study of the possible use of the ion milli- and micro-probes in a tomographic study of the ion track 3D geometry and its evolution during chemical etching.
