Characterization of RD53A modules using x-ray fluorescence — •Sascha Dungs1,2, Kevin Kröninger2, Susanne Kühn1, Lingxin Meng1, and Heinz Pernegger1 — 1CERN — 2TU Dortmund, Experimental Physics IV
As part of the Phase-II upgrade of the ATLAS detector, the current tracking detector will be replaced by an all-silicon detector, the Inner Tracker (ITk). For this, a new generation of silicon hybrid pixel modules are currently being developed. There are different techniques to investigate the properties of these modules. X-ray fluorescence can be used for energy calibration. An x-ray source is pointing on a target material, which leads to emission of photons with monochromatic energy. By using various target materials a wide energy range can be evaluated.
In this talk, results of x-ray fluorescence measurements of unirradiated and irradiated planar pixel modules with RD53A readout chips will be presented.
