Descripción
IFAE is involved in the development and production of pixel modules for both the Inner Tracker (ITk) and High Granularity Timing Detector (HGTD) upgrades of the ATLAS detector system, which are designed to address the challenges of the HL-LHC at CERN.
The innermost layer of the pixel system for the ITk will feature novel 3D silicon sensors with a thin active substrate and small pixel pitch, ensuring extreme radiation hardness. IFAE is evaluating the pre-production 3D sensors for the ITk. Pre-production module triplets, consisting of three 3D sensors hybridised to the ITk pixel ASIC and connected by a flexible PCB, are being assembled at the IFAE laboratory.
On the other hand, HGTD is a new detector aiming to provide timing information to tracks in the forward regions of ATLAS to reduce pile-up. It utilises pixel modules with Low Gain Avalanche Detectors (LGADs), capable of achieving a time resolution down to a few tens of picoseconds. IFAE is deeply involved in the evaluation of LGADs, front-end design, hybridisation process, and module assembly. More than 50 double chip modules have already been fully assembled and tested at IFAE. This presentation will highlight the ongoing activities and contributions of IFAE to both ITk and HGTD.
