Future frontier accelerators envisage the use of silicon sensors in
environments with fluences exceeding $1\times10^{17}$ 1-MeV $n_{eq}/cm^2$. Presently available silicon sensors can operate efficiently up to fluences of the order of some $10^{16}$ 1-MeV $n_{eq}/cm^2$. Therefore, novel sensors and readout electronics must be devised.
Within this framework, state-of-the-art Technology CAD...
We report on the characterization of 3D columnar-electrode sensors featuring 55 μm-pitch square and hexagonal pixel cells, evaluated with the Two-Photon Absorption Transient Current Technique (TPA-TCT) using the SSD laser facility at CERN. These sensors, manufactured at IMB-CNM, are double-sided n-in-p diodes with a thickness of 285 μm. The study provides detailed maps of the electric field...
We present the 3D scans of the latest 3D columnar silicon sensor technology, manufactured at the CNM-IBM (RD50 Common project). Double Sided Double Type Technology is studied. Hexagon structures ( 5x5 array of 3D Si cells) are compared to Quadratic structures (10x10 array of 3D Si cells). Timing study is performed using TCT set up at ELI (both SPA where we exploited two wavelengths and TPA...
SINTEF MiNaLab is currently producing part of the 3D pixel sensors for the ATLAS ITk upgrade. Given the number of sensors requested and the complexity of the technology, the production has been split into two 24-wafer batches (Run-7 and Run-8). The two batches have been carefully scheduled to avoid conflicts in the clean room. Both batches use the common sensor layout for RD53B sensors in...
The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) will demand the ATLAS detector to face an increased instantaneous luminosity up to $7.5\times 10^{34} cm^{−2} s^{−1}$ and an average of 200 proton-proton collisions per bunch-crossing. To cope with this challenge, the present ATLAS Inner Detector will be completely replaced with a new silicon-based Inner Tracker (ITk), made of a...
