Description
The Inner Tracker (ITk) of ATLAS is aimed for future High Luminosity LHC, where the challenges of energy density and radiation levels both exceed the current setup by an order of magnitude. It adopted an all-silicon design to be faster, more spatial segmented, and more radiation-resistant. The Strip Detector of ITk, which surrounds the Pixel Detector, will consist of a 4-layer double-sided Barrel detector to cover the central region, while the forward detector is a pair of 6-layer disk shaped End-cap at each side. In total 10976 barrel and 6912 end-cap detector modules will be assembled to cover 165.25 mm2 of area.
After the Repeated Final Design Report (rFDR), which was to verify a significant change in module design to address with the sensor cracking issue under the stress during thermal cycling, the collaboration has started the production of the first module batch. In this presentation, we will summarize the up-to-date design of the ITk strip modules, and introduce our current status of the production readiness.
