The silicon pixel tracking system for the ATLAS experiment at Large Hadron Collider is described and performance requirements are summarized. Detailed descriptions of detector electronics sensors given. design, fabrication, assembly modules presented. Data obtained from test beams as well studies using cosmic rays also discussed.
During the shutdown of CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between existing Pixel detector ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new layer, Insertable B-Layer (IBL), to maintain or improve robustness performance tracking system, given higher instantaneous integrated luminosities realised following shutdown. Because extreme radiation collision rate environment, several radiation-tolerant sensor electronic...

Abstract The Belle II collaboration has initiated a program to upgrade its detector in order address the challenges set by increase of SuperKEKB collider luminosity, targeting 6×10 35 cm 2 s -1 . A monolithic CMOS pixel sensor named OBELIX (Optimized BELle pIXel) is proposed equip 5 detection layers upgrading current vertex detector. Based on existing TJ-Monopix2, currently designed 180 nm process.
We describe the planned near-term and potential longer-term upgrades of Belle II detector at SuperKEKB electron-positron collider operating KEK laboratory in Tsukuba, Japan. These will allow increasingly sensitive searches for possible new physics beyond Standard Model flavor, tau, electroweak dark sector that are both complementary to competitive with LHC other experiments.
The demand for bendable sensors increases constantly in the challenging field of soft and micro-scale robotics. We present here, more detail, flexible, functional, insect-inspired curved artificial compound eye (CurvACE) that was previously introduced Proceedings National Academy Sciences (PNAS, 2013). This cylindrically-bent sensor with a large panoramic field-of-view \(180^\circ\) \(\times\) \(60^\circ\)composed 630 ommatidia weighs only 1.75 g, is extremely compact power-lean (0.9 W),...
