ATLAS silicon strip detector upgrade: towards the construction of a first Petalet — Dario Ariza¹, •Elin Bergeaas Kuutmann², Ingo Bloch¹, Conrad Friedrich², Ingrid-Maria Gregor¹, Marc Hauser³, Karl Jakobs³, Susanne Kuehn³, Heiko Lacker², Kambiz Mahboubi³, Riccardo Mori³, Ulrich Parzefall³, Luise Poley^1,2, Volker Prahl¹, Laura Rehnisch², and Dennis Sperlich² — ¹DESY, Germany — ²Humboldt-Universität zu Berlin, Germany — ³Albert-Ludwigs Universität Freiburg, Germany

After the planned upgrade in 2022, the LHC will run with an enhanced luminosity of 5· 10³⁴ cm⁻²s⁻¹. For ATLAS to handle the increased track density and radiation, a new Inner Detector must be developed and constructed. The upgraded silicon strip end-cap will consist of wedge-shaped parts, Petals. As a first step in the R&D, smaller, trapezoidal parts of the Petal, Petalets, are going to be constructed. The talk covers the steps already undertaken to build a first Petalet. First test results, such as thermal measurements, and the support structure will be discussed as well.
