Sensor quality testing for CMS HL-LHC upgrades*

In the upcoming High Luminosity LHC era, the Phase 2 upgrade CMS detector will feature an outer tracker (OT) built from silicon microstrip sensor modules. Several quality control (QC) tests and procedures have been established to test the parts of OT ensuring a high quality detector that meets the specification. The QC procedures includes visual inspections and measurements of specifications of physical structure, and measurements of electrical properties. We present here the QC tests developed that are essential to build a high quality detector.
