  In this work, charge collection profiles of non-irradiated and irradiated 150
$\mu$m $p$-type pad diodes were measured using a 5.2 GeV electron beam
traversing the diode parallel to the readout electrode. Four diodes were
irradiated to 1 MeV neutron equivalent fluences of 2, 4, 8, and 12E15 {cm}^{-2}
with 23 MeV protons. The Charge Collection Efficiency profiles as a function of
depth are extracted by unfolding the data. The results of the measurements are
compared to the simulation using three radiation damage models from literature
which were tuned to different irradiation types and fluences.
