After more than 3 years of successful operation at the LHC, we report on the
operation and performance of the ATLAS Semi-Conductor Tracker (SCT) functioning in a high luminosity, high radiation environment. 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,...

The CMS silicon tracker is the largest silicon detector ever built. It consists of a hybrid pixel detector with 66 million channels and a 200 m2 silicon strip detector with 10 million read out channels. The presentation describes the operation of this detector during data taking years before the current LHC shutdown, both during proton-proton as well as heavy ion collisions. Results on the...

The ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at the Large Hadron Collider at CERN. The detector provides hermetic coverage with three cylindrical layers and three layers of forward and backward pixel detectors. It consists of approximately 80 million pixels that are individually read out via chips bump-bonded to 1744 n-in-n silicon substrates. In this talk,...

Tracking Systems
The CMS tracker is the largest silicon detector ever built, covering 200 square meters and providing an average of 14 high-precision measurements per track. Tracking is essential for the reconstruction of objects like jets, electrons and tau leptons. Track reconstruction is widely used also at trigger level as it improves lepton and jet resolution and allows to pre-identify tau leptons and...

GigaTracker, the NA62's upstream spectrometer, plays a key role in the kinematically constrained background suppression. It is made of three independent stations, each of which is a six by three cm2 hybrid silicon pixels detector. In order to meet the physics goals of NA62 the pixel hit time resolution must be better than 200 ps. The material budget must be kept less than 0.5 % X0.
The 200µm...

GaN and SiC power devices were extensively tested under different types of radiation, in the framework of the APOLLO R&D collaboration, aiming to use these new technologies for designing power supplies for the future LHC experiments upgrades.
SiC power MOSFETs were irradiated with gamma-rays, neutrons, protons and heavy ions (Iodine, Bromine) at different energies (20MeV - 550MeV). They...

The LHC at CERN is now the highest energy and luminosity collider in the world. Upgrades to the accelerator are currently being planned to further increase the energy and luminosity. The detectors must be upgraded to take advantage of the planned accelerator upgrades. This requires the optical links to transmit data at much higher speed to handle the much increased luminosity. We will present...

We report on the fabrication, electrical characterization and particle detection performance of the first prototype of a 3D diamond detector for applications in particle physics. The 3D detector geometry has the advantage of small carrier drift paths, which allows in diamond for nearly full charge collection after large doses of radiation. Polycrystalline and single-crystal CVD diamond...

3D detectors whose electrodes extend perpendicularly to the sensor surface are one of the solution proposed for the challenges of radiation-harsh environments in high energy physics.
We report on the fabrication and characterization of prototypes of 3D diamond sensors, which add to the 3D architecture the advantages of diamond as a sensor for tracking purposes.
Two different laser sources,...

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 is currently under construction and will be installed during the first shutdown of the LHC machine, in 2013-14. The new detector, called the Insertable B-layer (IBL), will be installed between the existing...

ATLAS is planning to use a hardware processor, the Fast Tracker (FTK), to perform tracking at the level1 event rate (100 KHz).
The most recent prototype of the Associative Memory (AM) chip developed for the ATLAS Fast Tracker includes ternary logic that can store the “don’t care” (DC) value. This feature allows enormous flexibility tuning to the precision of the match for each pattern and...

The CMS Collaboration has launched an extensive R&D program to explore the new generation semiconductor detector technologies capable to face the radiation hardness challenges waiting in the near future. This HPK campaign aims to determine which sensor material, polarity and geometries will work best under the foreseen conditions. The presented beam test results help determining the best...

A prototype of an Si-W EM calorimeter was built with Monolithic Active Pixel Sensors as the active elements. With a pixelsize of 30 um it allows digital calorimetry, i.e. the particle’s energy is determined by counting pixels, not by measuring the energy deposited. Although of modest size, only 4 Moliere radii wide, it has 39 million pixels and its calibration appears far from trivial.
The...

PANDA is a key experiment of the future FAIR facility. It will study the collisions between an antiproton beam and a fixed proton or nuclear target. The Micro Vertex Detector (MVD) is the innermost detector of the appa- ratus and is composed of four concentric barrels and six forward disks, instrumented with silicon hybrid pixels and double-sided silicon microstrips; its main task is the...

Proton Computed Tomography (pCT) is a medical imaging technique based on the use of proton beams with energies above 200MeV to directly measure stopping power distributions inside the tissue volume. Prima (PRoton IMAging) is an italian collaboration working on the development of a pCT scanner based on a tracker and a calorimeter to measure single protons trajectory and residual energy. The...

The concept of a homogeneous, isotropic, and high dynamic range calorimeter has been developed and a prototype has been built and tested. The most suitable geometry was found to be cubic and isotropic, so as to detect particles arriving from every direction in space, thus maximizing the acceptance; granularity is achieved by subdividing the cubic volume in smaller cubic crystals. A dual...

We propose an innovative system for real time monitoring of short and
medium term radioactive waste repositories. Such a system behaves like a cheap scintillating Geiger-Muller counter and it is based on a new kind of gamma mini-sensor, developed at INFN-LNS, assembled with low-cost components: Silicon PhotoMultipliers and scintillating fibers. Front-end electronics and an FPGA-based counting...

Edge-TCT (where TCT stands for Transient Current Technique) is a new experimental method for segmented detectors where a focused laser beam is injected from the side of the device. Using a beam much smaller than the thickness of the device under study, the drift of the induced charge carriers can be studied as a function of the injection position. Intrinsic properties of the devices can be...
