Effects of the radial density distribution of carriers generated in a singl
e ion track have been observed in thin silicon detectors. These devices hav
e been irradiated with either an ion microbeam at low energy or a high-ener
gy standard ion beam. We describe the mode of operation of the tested struc
ture, and propose an interpretation of the experimental charge collection d
ata to extract information on the ion track profile. Experimental results a
re compared to 3D simulations and simplified analytical profiles.
