The upgrade of the LHCb experiment, planned for 2018, will transform the experi-
ment to a trigger-less system reading out the full detector at 40 MHz event rate. All
data reduction algorithms will be executed in a high-level software farm with access to
the complete event information. This will enable the detector to run at luminosities of
2 1033cm-2s-1 and probe physics beyond the...

The development of silicon detectors tolerant to extreme fluences for future high energy and high luminosity hadron colliders (like the upgrade of the present Large Hadron Collider to high luminosity at CERN) is demanded not only for instrumenting the innermost layers (where pixel sensors will be deployed) but also for particle flow calorimetry. The anticipated fluence levels range from...

We present results of n-in-p pixel sensor prototypes of 100 to 270 μm thickness with different designs, focusing on alternative implementations of punch-through structures. A comparative study has been performed on pixel modules by means of radioactive sources and beam test measurements at the CERN-SPS and DESY. The results of these measurements will be discussed for devices irradiated up to a...

It is known that for the current design of planar pixel sensors, there is a drop of efficiency at the punch-through structure of the biasing system at the edge of pixels. Various geometries, as part of the ATLAS Inner Tracker (ITK) upgrade, are being investigated to reduce this inefficiency.
Planar pixel sensors with multiple alternative bias rail geometries have been tested at the SPS beam...

Surface properties of ATLAS12 n-on-p silicon sensors developed for the upgrade of the strip tracker of the ATLAS experiment were evaluated before and after irradiation. Different types of end-cap and barrel mini sensors were irradiated by gamma and protons at different irradiation sites. Influence of different sensor geometries, wafer resistivities and types of PTP structures on sensor...

The CMS collaboration is planning to upgrade the forward calorimeters as these will not be sufficiently performant with the expected HL-LHC (High Luminosity LHC) conditions. After CMS committee decision, the High Granularity Calorimeter (HGC) is the technology chosen for this upgrade. It is realized as a sampling calorimeter with layers of silicon detectors that feature very high longitudinal...

Recently it has been shown that silicon strip detectors, especially irradiated and showing charge multiplication, have decreasing performance when tested for several days under high voltage conditions.
This behaviour has been in some cases explained in some cases by a surface effect[1], coming from the dose released in the silicon oxide by the source used for the measurements. Other...
