Production of EC electronics hybrid circuits for the ATLAS InnerTracker at the Large Hadron Collider

are recorded by large-scale detector systems. A major upgrade of the ATLAS experiment involves the replacement of its inner tracking detectors. The upgraded tracker will comprise approximately 18,000 single-sided silicon microstrip detector modules. It will consist of five concentric barrel layer

s and six end-cap disks on each side. The detector modules in the barrel will be produced in two different geometries, while those in the end-caps will include nine distinct geometrical types. This procurement includes industrial producti
