Abstract
The all-silicon ATLAS ITk Detector, vertexing and tracking device for the High-Luminosity LHC project, should operate at an ultimate peak instantaneous luminosity up to 7.5 x 1034 cm-2 s -1 corresponding to approximately 200 inelastic proton-proton interactions per beam crossing. The ITk Strip Detector will consist of four barrel layers and six disks in a forward region on each side of the barrel.
They will be composed of individual structures called staves and petals, whose production will require almost 18,000 single-sided strip modules of 8 different designs with the hybrid circuits carrying the front-end microelectronics ASICs glued to the sensor surface. The sensing elements are high resistivity n-in-p silicon strips capable of withstanding fluences up to 1.2x1015 neq/cm2.
Both irradiated and non-irradiated prototypes of strip modules undergo testing procedures including test beam campaigns supplemented by laser and beta source tests to check if they meet the design requirements of the detector.
