Abstract The ATLAS experiment is constructing new all-silicon inner tracking system for HL-LHC. strip detectors cover the radial extent of 40 to 100 cm. A approach adopted use p-type silicon material, making readout in n + -strips, so-called -in-p sensors. This allows enhanced radiation tolerance against an order magnitude higher particle fluence compared LHC. To cope with varying hit rates and occupancies as a function distance, there are two barrel sensor types, short strips (SS) 2 long...
For the Phase-II Upgrade of ATLAS Detector [1], its Inner Detector, consisting silicon pixel, strip and transition radiation sub-detectors, will be replaced with an all new 100% tracker, composed a pixel tracker at inner radii outer radii. The future include 11,000 sensor modules in central region (barrel) 7,000 forward (end-caps), which are foreseen to constructed over period 3.5 years. construction each module consists series assembly quality control steps, were engineered identical for...
Abstract The ATLAS experiment at the Large Hadron Collider (LHC) is currently preparing to replace its present Inner Detector (ID) with upgraded, all-silicon Tracker (ITk) for High-Luminosity upgrade (HL-LHC). ITk will consist of a central pixel tracker and outer strip tracker, consisting about 19,000 detector modules. Each module assembled from up two sensors, five flexes (depending on geometry) in series gluing, wirebonding quality control steps. During operation, modules be cooled down...
Streams of event weights in particle-level Monte Carlo generators are a convenient and immensely CPU-efficient approach to express systematic uncertainties phenomenology calculations, providing variations on the nominal prediction within single sample. But lack common standard for labelling these variation streams across different tools has proven be major limitation event-processing analysers alike. Here we propose well-defined, extensible community naming, ordering, interpretation weight...

To cope with increased rates data, radiation, and pileup, ATLAS detector undergo a substantial upgrade, including replacement Inner Detector future Tracker, called ITk. The ITk composed pixel strip sub-detectors, where strips portion 17,888 silicon modules. During HL-LHC running period, cooled warmed...
Abstract The high-luminosity upgrade of the Large Hadron Collider, scheduled to become operational in 2029, requires replacement ATLAS Inner Detector with a new all-silicon Tracker.

A bstract Pixel tracklets, disappearing tracks reconstructed with only pixel hits, have proven to be a promising technique in LHC analyses search for dark matter candidates at the that belong nearly-degenerate electroweak multiplet. However, Pseudo-Dirac doublet fermion, arguably most interesting such possibility, has shorter lifetime and therefore existing tracklet searches are less sensitive this case. We assess performance of optimized lifetimes by requiring three hits reconstruction,...
We investigate the signal propagation in AC-LGAD (aka RSD), which are LGAD with a common N+ layer and segmented AC-coupled readout contacts, by measuring response to IR laser TCT on large selection of strip readout. The interest for this topic derives from realization that while charge sharing between neighboring strips is essential good position resolution, beyond next neighbor generates background signals general detrimental sensor goal low occupancy. Using produced Hamamatsu Photonics...
Abstract Advances in timing detector technology require new specialized readout electronics. Applications demand below 10 ps time of arrival resolution and low power for a repetition rate. A possible path to achieve O(10 ps) is an integrated chip using Silicon Germanium (SiGe) technology. Using DoE SBIR funding, Anadyne, Inc., collaboration with UC Santa Cruz, has developed prototype SiGe front-end optimized resolution. Two versions the were produced performance simulation: more version at 5...

The instantaneous luminosity of the Large Hadron Collider at CERN will be increased by up to seven times its design value undergoing an extensive upgrade program over coming decade.
