Characterization of ALPIDE silicon sensors with inclined tracks

Popis výsledku v původním jazyce

The upgrade of the ALICE Inner Tracking System (ITS) aims at improving the capabilities of ALICE in terms of read-out rate as well as track pointing resolution and track finding efficiency, especially for particles with low transverse momenta. The new ITS will be a low material budget detector with high granularity and read-out speed. It comprises seven concentric layers of Monolithic Active Pixel Sensors (MAPS) with a total active surface of about 10 m2. The developed MAPS are based on the TowerJazz 180 nm CMOS technology. The sensor is called ALPIDE.nIn this paper, we present the setup used for measurements with inclined tracks and we discuss the sensor efficiency obtained using π beams with a momentum of 6 GeV/c at the Proton Synchrotron (PS) at CERN. Some sensors were irradiated before the beam test using the cyclotron facility of the Nuclear Physics Institute of the Czech Academy of Sciences (NPI CAS) to induce radiation damage to the sensor. Measurements at different operating points (thresholds, bias voltages) provide important information about cluster-shape frequencies, needed to tune the ALICE Monte-Carlo generators.nA very good agreement between test-beam data and simulations is obtained.
