Description
The ALPIDE telescope is a continuously evolving tracking telescope based on the TowerJazz 180 nm CMOS ALICE PIxel DEtector (ALPIDE). The ALPIDE is a high efficiency, high spatial resolution monolithic active pixel sensor designed for the recently commissioned ALICE Inner Tracker System (ITS2).
This telescope is one of the main R&D tools for the test and characterization of new sensors and devices in view of the future tracker upgrades.
One such sensor is the Digital Pixel Test Structure (DPTS), produced using the TPSCo 65 nm CMOS imaging process. It consists of a 32 by 32 matrix of 15 um by 15 um pixels featuring time-based encoding of a hit position.
Both non-irradiated and irradiated DPTS performance is assessed with 5.4 GeV/c and 3.4 GeV/c electron tracks measured with the ALPIDE telescope at DESY Test Beam Facility.
In this talk, the test beam measurements with the ALPIDE telescope and the analysis of the DPTS performances will be presented.
