Studies of charge transport uniformity in bulk CdTe : Cl have been carried out using ion beam induced charge (IBIC) imaging. High resolution maps of charge collection efficiency, mobility-lifetime product (mutau) and drift mobility (mu) were measured using a scanning microbeam of 2 MeV protons focused to a beam diameter of ~3 mum. Excellent charge transport uniformity was observed in single crystal CdTe : Cl, with electron mutau values of up to 5·10-3 cm2/Vs. The presence of extended defects such as tellurium inclusions was also studied using IBIC, and their influence on the charge transport performance of CdTe detector structures is discussed.
