Electrical Tests with the ITk Pixel Outer-Barrel Demonstrator — •Hans Joos1,2, Benedikt Vormwald1, Leyre Flores Sanz De Acedo1, Brian Moser1, Stan Lai2, and Anne Gaa2 — 1CERN — 2II. Physikalisches Institut, Georg-August-Universität Göttingen
For the upgrade of the LHC to the High-Luminosity LHC (HL-LHC), the ATLAS tracking detector will be replaced with an all-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. The Outer-Barrel layers of the pixel detector will comprise quad chip modules that are combined into serially powered (SP) chains and loaded on ring and stave shaped low mass carbon-fibre local supports to reduce the material budget of the detector.
The integration from individual detector components to a final detector is one of the big challenges of the HL-LHC detector upgrades. In order to test the loading procedure and performance of the modules after loading, prototype modules were mounted on a stave local support and connected with realistic services to form a smallest "feature-complete" functional building block and demonstrator of the ITk Pixel Outer-Barrel detector.
This talk will explain the demonstrator setup and present the results of electrical performance tests of the demonstrator modules after loading and their behavior in SP chains.
