ITk-pixel outer barrel demonstrator — Jörn Große-Knetter1, Susanne Kühn2, •Silke Möbius1, Arnulf Quadt1, Benedikt Vormwald2, and Hua Ye1 — 1II. Physikalisches Institut, Georg-August-Universität Göttingen — 2CERN
For the upgrade of the LHC to the High-Luminosity-LHC, the ATLAS tracking detector will be replaced with a pure silicon detector, the Inner Tracker (ITk), as the higher luminosity requires radiation hard components that can deal with higher occupancies and radiation. Given the close proximity to the interaction point, the environment is especially challenging for the pixel detector which will comprise quad chip modules for outer barrel layers.
In order to characterize and test ITk-pixel prototype quad modules, up to 40 modules are built and tested for the outer barrel demonstrator. This so-called demonstrator is a larger structure which features some of the final mechanics to test the system functionalities. Systems like an interlock need to be implemented and tested and the modules behaviour before and after being powered in serial needs to be examined to allow for thorough tests.
After having done initial tests with a preliminary version of the demonstrator with older modules, the preparation of the set-up and commissioning of the new demonstrator is currently ongoing.
This talk will give an overview over the current state of the demonstrator, explain the set-up and summarize the potential tests to be performed on the demonstrator.
