The ATLAS collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing and vacuum pipe of Large Hadron Collider. extreme operating conditions at this location have necessitated development radiation hard sensor technologies front-end readout chip, called FE-I4. Planar sensors 3D been investigated to equip layer, prototype modules using FE-I4A fabricated characterized 120 GeV pions CERN SPS 4 positrons DESY, before after module...

This paper describes the design, construction, and initial operation of SLD's upgraded vertex detector which comprises 96 two-dimensional charge-coupled devices (CCDs) with a total 307 Mpixel. Each pixel functions as an independent particle detecting element, providing space point measurements charged tracks typical precision 4 μm in each co-ordinate. The CCDs are arranged three concentric cylinders just outside beam-pipe surrounds e+e− collision SLAC Linear Collider (SLC). is powerful tool...

Deep level transient spectroscopy has been used to investigate defects in high resistivity silicon diodes after neutron irradiation. Three have correlated with the leakage current. The current is found be a factor of 50 600 greater than expected from standard Shockley-Read-Hall (SRH) theory for observed defect-concentrations. results can explained by an enhancement due intercentre transfer charge between close proximity each other. It proposed that possible mechanism this process rapid,...

The subject of radiation damage to Si detectors induced by 24-GeV/c protons and nuclear reactor neutrons has been studied. Detectors fabricated on single-crystal silicon enriched with various impurities have tested. Significant differences in electrically active defects found between the types material. results study suggest for first time that widely used nonionizing energy loss (NIEL) factors are insufficient normalization case oxygen- carbon-enriched detectors. It a deliberate...

Silicon detectors for the Roman Pots of large hadron collider TOTEM experiment aim full sensitivity at edge where a terminating structure is required electrical stability. This work provides an innovative approach reducing conventional width to less than 100 microns, still using standard planar fabrication technology. The objective this new development decouple electric behaviour surface from sensitive volume within tens microns. explanation basic principle together with experimental...

The top quark and electroweak bosons (W Z) represent the most massive fundamental particles yet discovered, as such refer directly to Standard Model's greatest remaining mystery: mechanism by which all gained mass. This report summarizes work done within top-ew group of Tevatron-for-LHC workshop. It represents a collection both Tevatron results, LHC predictions. hope is that considering comparing machines, program can be improved aided knowledge from Tevatron, particle physics whole...
