The UK has produced a number of pixel sensors based on the FEI4b chip for ATLAS ITk. These sensors vary in pixel dimension and coupling technology. This talk will present progress in characterising these devices, including a comparison of pixel geometries based on cluster parameters and resolution at CERN and DESY testbeams.

Hybrid pixel-detector prototypes with small pitch (25-55 microns) and thin sensors (50-300 microns) are currently under study for the vertex detector at the proposed high-energy CLIC electron-positron collider. Test-beam campaigns with hybrid assemblies of planar and active HV-CMOS sensors on CLICpix ASICs and with active edge sensors on Timepix3 ASICs have been performed at the CERN SPS H6...

Based on the strong performance of the LHC accelerator, it is anticipated that peak luminosities of two times the design luminosity of L = 2 x10^34 cm^-2s^-1 are likely to be reached before 2018 and probably significantly exceeded in the so-called Phase I period until 2022. At this higher luminosity and increased hit occupancies the current CMS pixel detector would be subject to severe dead...

3D FEI4 pixel detectors from the IBL production were non-uniformly irradiated at CERN-PS with 23 GeV protons up to a maximum fluence of 9e15 neq/cm2. The devices have been studied in beam tests at CERN SPS and good efficiencies of >97% have been achieved at the highest fluence already at 170 V. Especially interesting is the option to study a vast range of fluences on a single pixel device due...

The DAFNE Beam Test Facility (BTF) is a beam transfer line optimized to produce single electrons/positrons for detector performances assessment. This contribution will describe the implementation in this facility of an ultra-thin and high spatial resolution beam telescope for the performances assessment of large pixel CMOS sensors designed to instrument the outer layers of an inner tracker.

A micro-focused (2.5um spot size) 15keV X ray beam has been used to study silicon micro-strip and pixelated detectors that utilise reduced edge or edgeless designs.
Scans were taken across the physical edges of devices to measure the charge collection as well as study the electric field line behaviour.
We will show the methods used for alignment, DAQ integration, triggering and data...

The intrinsic resolution of the MIMOSA26 sensors used in the DATURA beam telescope are extracted deploying an iterative method using GBL track fits. The data was taken at the DESY-II test beam facilities. Additionally, the applicability of the Highland formula to electron beams is tested against data.

The ATLAS Forward Proton (AFP) project intends to measure protons scattered under a small angle from the ATLAS proton-proton interaction point.
To this end, it is planned to install 3D Silicon pixel and Quartz-Cherenkov time-of-flight detectors 210 m away from the interaction point.
Beam tests with a first unified AFP prototype detector combining tracking and timing sub-detectors and a...

The high-luminosity upgrade of the Large Hadron Collider, foreseen for 2025, neces-
sitates the replacement of the tracker of the CMS experiment. The innermost layer of
the new pixel detector will be exposed to severe radiation corresponding to a 1 MeV
neutron equivalent fluence up to Φ eq = 2 · 10 16 cm −2 and an ionizing dose of ≈ 10 MGy
after an integrated luminosity of 3000 fb −1 ....

The upgrade of the LHCb experiment, planned for 2019, will transform the experiment
to a trigger-less system reading out the full detector at the LHC collision rate
and up to $2\times 10^{33}cm^{−2} s^{-1}$ instantaneous luminosity.
The Vertex Locator (VELO) is the silicon detector surrounding the interaction region.
The upgraded VELO is based on a hybrid pixel system equipped...
