Description
In this work, charge collection profiles of non-irradiated and irradiated $150 \; \mu \text{m}$ $p$-type pad diodes were measured using a $5.2 \; \text{GeV}$ electron beam traversing the diode parallel to the readout electrode. Four diodes were irradiated to $1 \; \text{MeV}$ neutron equivalent fluences of 2, 4, 8, and $12 \times 10^{16} \; \text{cm}^{-2}$ with $23 \; \text{MeV}$ protons. By unfolding the measured charge collection profiles, the Charge Collection Efficiency profiles are extracted as a function of depth. 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.
