Strip sensor characterization for the ATLAS ITk tracker — •Elizaveta Sitnikova — DESY, Hamburg, Germany

Before the start of High Luminosity LHC the Inner Detector of the ATLAS detector will reach the end of its operating life. It will be replaced by a new Inner Tracker (ITk), more suitable for high luminosity. Building the ITk requires a lot of effort from many institutes in the collaboration, and DESY is one of the main contributing institutes. One of the two strip ITk endcaps will be assembled at DESY. During production, the main sensing units of the tracker, the silicon microstrip sensors, have to pass a number of tests to ensure that they are suitable for becoming part of the detector. One of these tests is measuring the IV sensor characteristic. In this talk the importance and the procedure of measuring strip sensor IV curves at DESY Hamburg will be discussed, as well as a detailed study of whether the number of required IV testing can be reduced, done using high statistics provided by the current data stored in the ITk production database.
