New pixel sensors are currently under development for ATLAS Upgrades. The first upgrade stage will consist in the construction of a new pixel layer that will be installed in the detector during the 2013 LHC shutdown. The new layer (Insertable-B-Layer, IBL) will be inserted between the inner most layer of the current pixel detector and the beam pipe at a radius of 3.2cm. The expected high...

While the Large Hadron Collider (LHC) at CERN is continuing to deliver an ever-increasing luminosity to the experiments, plans for an upgraded machine called Super-LHC (sLHC) are progressing. The upgrade is foreseen to increase the LHC design luminosity by a factor ten. The ATLAS experiment will need to build a new tracker for sLHC operation, which needs to be suited to the harsh sLHC...

To extend the physics reach of the LHC, upgrades to the accelerator are planned which will allow to boost the integrated luminosity delivered to the experiments from about 700/fb to 3000/fb. To achieve this, the peak luminosity will have to rise by a factor 5 to 10 which leads to increased occupancy and radiation damage of the tracking detectors.
To cope with the elevated occupancy, the...

When a minimum ionizing particle crosses an aluminium foil, at least one low energy electron is emitted, at the crossing point, in about 6 percent of the cases. With low work function materials (ceramics, or CsI, diamond), this probability may be much higher. Since only the skin of the foil participates, the efficiency to emitat least one electron can be increased by surface enlargement...
