Lorentz angle measurement on ATLAS silicon microstrip sensors — Ingrid Maria Gregor1, Kerstin Tackmann1, and •Eda Yildirim1,2 — 1DESY, Hamburg, Germany — 2Universität Hamburg, Hamburg, Germany
The Large Hadron Collider (LHC) at CERN in Geneva is scheduled to run in its present form until 2021. After that, an upgrade to a higher instantaneous luminosity of 5 × 1034cm−2s−1 (High-Luminosity LHC) is planned. At the same time, the current ATLAS tracking system which consist of a pixel detector, a strip detector and a transition radiation tracker, will be replaced by an all-silicon tracker (pixels and strips). During High-Luminosity LHC running, they will be subject to high radiation levels. The silicon microstrip detector will have to withstand radiation doses up to 1015 neq/cm−2. As a result of the radiation damage, the Lorentz angle of the strip sensors is expected to change. In this talk, a test beam setup prepared to measure the Lorentz angle of future ATLAS silicon microstrip sensors will be presented and first preliminary results will be shown.
