Testing of loaded local supports of the ATLAS Inner Tracker — •Wael Alkakhi, Joern Grosse-knetter, and Arnulf Quadt — II. Physikalisches Institut, Georg-August-Universität Göttingen

During the third long shut down (LS3) of the Large Hadron Collider (LHC), a high luminosity upgrade takes place in which the instantaneous luminosity reaches 7.5 × 10³⁴cm⁻²s⁻¹ in Run 4. The current inner detector of the ATLAS experiment is going to be replaced by inner tracker (ITk). ITk is composed of a pixel detector surrounded by a strip detector. The pixel detector consists of 5 layers where the first 2 layers represent the inner pixel detector and the last 3 layers represent the outer barrel and the endcap. The outer barrel consists of 4474 modules. These modules are mounted on loaded local supports of which there are two types : loaded longeron and loaded inclined half ring. Due to the large number of elements used during the assembly and production of the ITk, the ITk production database is used to store and track the information of the ITk components. Moreover a graphical user interface (GUI) is used to ease working with the ITk production database during the production of the ITk outer barrel.

This talk introduces the integration procedure of modules to local supports. Moreover it demonstrates my contribution to the implementation of the loaded local supports in the ITk production database and the GUI developments.
