The Semi-Conductor Tracker (SCT) is a silicon strip detector and one of the key precision tracking devices in the Inner Detector of the ATLAS experiment at CERN LHC.
The SCT is constructed of 4088 silicon detector modules for a total of 6.3 million strips. Each module is designed, constructed and tested to operate as a stand-alone unit, mechanically, electrically, optically and thermally. The...

The VELO is the silicon detector surrounding the LHCb interaction point. The sensors have an inner radius of only 7mm from the LHC beam and an outer radius of 42 mm. Consequently the sensors receive a large and non-uniform radiation dose. A dose of 0.5 x 10^13 1 MeV neutron equivalents /cm^2 per fb^-1 of data is predicted at the tip of the sensors. The sensors are fabricated from oxygenated...

The upgrades for the ATLAS Pixel Detector will be staged in preparation for high luminosity LHC. The first upgrade for the Pixel Detector will be the construction of a new pixel layer which will be installed during the first shutdown of the LHC machine, foreseen in 2013-14. The new detector, called the Insertable B-layer (IBL), will be installed between the existing Pixel Detector and a new,...

ATLAS plans a first major upgrade of its pixel detector on the path to HL-LHC in form of the IBL: The insertion of a 4th pixel layer (Insertable B-Layer) is currently being prepared for 2013. This will enable the ATLAS tracker to cope with an increase of LHC's peak luminosity to about 3E34 cm-2 s-1 which requires a radiation hardness of the sensors of up to 5E15 n_eq cm-2.
As part of their...

this talk will report an overview on the developement of 3D silicon sensors for the ATLAS IBL. The experience of qualifying, producing and testing 3D sensors compatible with the FE-I4 pixel readout electronic chip will be discussed together with an indication of the future perspectives on the use of micromachining in radiation detection.

The CMS experiment is equipped with a 3 layer pixel detector for track seeding and vertexing. The talk gives a short description of the detector and its performance. During 2011 first radiation induced changes of the modules became noticable. This concerns the leakage current of the sensors, and the full depletion voltage, but also some parameters of the readout electronics.
It is planned...
