Characterization of a pixelated CdTe Timepix detector operated in ToT mode
Original language description
A 1 mm thick CdTe sensor bump-bonded to a Timepix readout chip operating in Time-over-Threshold (ToT) mode has been characterized in view of possible applications in particle and medical physics. The CdTe sensor layer was segmented into 256 x 256 pixels, with a pixel pitch of 55 μm. This CdTe Timepix device, of ohmic contact type, has been exposed to alpha-particles and photons from an (2)⁴¹Am source, photons from a ¹37Cs source, and protons of different energies (0.8–10 MeV) delivered by the University of Montreal Tandem Accelerator. The device was irradiated on the negatively biased backside electrode. An X-ray per-pixel calibration commonly used for this type of detector was done and its accuracy and resolution were assessed and compared to those of a 300 μm thick silicon Timepix device. The electron mobility-lifetime product (μ<sub>e</sub>τ<sub>e</sub>) of CdTe for protons of low energy has been obtained from the Hecht equation. Possible polarization effects have been also investigated. Finally, information about the homogeneity of the detector was obtained from X-ray irradiation.
