Silicon sensors with various pixel geometries adapted for a common readout ASIC / Milovanovic, Marko (Liverpool U.) ; Burdin, S (Liverpool U.) ; Dervan, P (Liverpool U.) ; Buttar, C (Liverpool U.) ; Bates, R (Liverpool U.) ; Blue, A (Liverpool U.) ; Doonan, K (Liverpool U.) ; Wraight, K G (Liverpool U.) ; Mcmullen, T (Liverpool U.) ; Stewart, A (Liverpool U.) et al. /ATLAS UK Pixels
ATLAS is proposing to replace the entire tracking system for HL-LHC operation. The ``Letter of Intent'' baseline pixel size at higher radii was 50 × 250μm(2) (varphi × η), based on the FE-I4 readout chip, and this was optimized for the central barrel region. [...]

Pixel sensors with different pitch layouts for ATLAS Phase-II upgrade / Dervan, Paul (Liverpool U.)
Different pitch layouts are considered for the pixel detector being designed for the ATLAS up- graded tracking system which will be operating at the High Luminosity LHC. The tracking per- formance in the Endcap pixel regions could benefit from pixel layouts which differ from the ge- ometries used in the barrel region [...]

Development of a test beam telescope based on the ATLAS front end ASIC FE-I4 / Obermann, Theresa (Bonn U.)
A beam telescope using FE-I4 readout chip based pixel modules of the ATLAS IBL upgrade was set up and tested. The data acquisition as well as the analysis were adopted from an already existing framework developed specifically for that purpose, namely EUDAQ and EUTelescope. [...]

Capacitively Coupled Pixel Detectors: From Design Simulations to Test Beam / Vicente Barreto Pinto, Mateus (Geneva U.)
Capacitively Coupled Pixel Detectors (CCPDs) are now possible due to new HV-CMOS sensors, where the high voltage (necessary to deplete the sensor) can be applied on CMOS circuits, allowing the sensor to be capacitively coupled to a read out ASIC, avoiding the expensive bump-bonds. An extensive characterisation work, in the ATLAS ITk Upgrade framework, is done in this new sensor technology. [...]

Characterisation of new hybrid pixel module concepts for the ATLAS Insertable B-Layer upgrade / Backhaus, M
For the ATLAS pixel detector, a fourth hybrid pixel detector layer known as Insertable B-Layer (IBL) is developed, which will be slid into the present pixel detector. Due to the very small distance to the interaction point of about 3.4 cm, the IBL will improve the track reconstruction and vertexing of the pixel detector. [...]
