Abstract The high-luminosity upgrade to the LHC requires a new silicon-strip charged-particle tracking detector for ATLAS. HCC (Hybrid Controller Chip) is one of three radiation-tolerant ASICs this detector. As interface multiple binary readout ASICs, responsible buffering and forwarding control signals requests them as well serializing their data into 640 Mbps output. All HCCs undergo suite tests verify analog digital functionality. yield exceeds 90% target production.
Abstract For the high-luminosity upgrade to LHC, ATLAS Inner Detector will be replaced by an all-silicon tracker (ITk) consisting of two systems: pixels and strips. HCC AMAC are ITk Strip ASICs vital for performing system readout, monitoring, control. To ensure these successfully operate in high-radiation environment HL-LHC, they need tested radiation tolerance, tests have been performed using both heavy ions protons. The ASIC designs were shown protect against single event effects due radiation.
Abstract The ATLAS detector requires an all new inner detector, the Inner Tracker (ITk), due to high-luminosity upgrade LHC (HL-LHC). AMACStar chip is one of three radiation hard ASICs that will be installed on ITk Strip subdetector modules. ASIC operates autonomously and its function monitor control temperatures, voltages, currents in module components, preventing these quantities from reaching dangerous levels. A total 18000 AMACStars are needed for subsystem. Wafers chips probed at...
Abstract The ATLAS experiment is currently preparing for an upgrade of the inner tracking detector High-Luminosity LHC. new tracker, ITk, employs all-silicon with outer strip layers. building block ITk barrel stave which consists a low-mass support structure hosting common electrical, optical and cooling services as well 28 silicon modules. In this contribution, we outline challenging aspects pre-production testing phase at Brookhaven National Laboratory. electrical characterization these...
Abstract For the high-luminosity phase of LHC, which begins operation in 2029, current ATLAS inner detector will be replaced by a new tracker, ITk. The ITk consists two subdetectors, one using pixels and second silicon-strips, Strip detector. HCC AMAC chip are radiation-tolerant ASICs that contribute to front-end readout, monitoring control subsystem. Low temperature startups low internal regulated voltage tests have been performed on guarantee their reliability at edge conditions. In...
We present results on the production of high transverse momentum charm mesons in collisions 515 GeV/c negative pions with beryllium and copper targets. The experiment recorded a large sample events containing (pT) showers detected an electromagnetic calorimeter. From these data, has been reconstructed via their decay into fully charged Kππ mode. A measurement single inclusive distribution D from 1 to 8 is presented. An extrapolation measured differential cross section yields integrated D±...
Although the standard model of particle physics (SM) is remarkably successful at describing fundamental particles and their interactions, mechanism for breaking elecroweak symmetry (EWSB) has yet to be confirmed. In SM, EWSB sector consists four scalar fields represented by a single SU(2) complex doublet. Following EWSB, three are responsible generation W{sup {+-}} Z masses, while fourth neutral Higgs boson. At present time, Tevatron experiments have set 95% CL exclusion limits on mass SM...
Abstract For the High-Luminosity upgrade of LHC, current ATLAS inner detector will be replaced with a new silicon charged-particle tracker, ITk, which consists ITk Pixel and Strip subdetector. The high voltage multiplexing (HV-Mux) GaNFETs are radiation-tolerant transistors that permit switching off to malfunctioning sensors on modules. To ensure reliability in radiation environment expected at HL-LHC, sample production batch was exposed gamma radiation. were characterized pre-irradiation...
The Fermilab Proton-Improvement-Plan-II (PIP-II) is being implemented in order to support the precision neutrino oscillation measurements at Deep Underground Neutrino Experiment, U.S. flagship experiment. PIP-II LINAC presently under construction and expected provide 800~MeV protons with 2~mA current. This white paper summarizes outcome of first workshop on May 10 through 13, 2023, exploit this capability for new physics opportunities kinematic regime that are unavailable other facilities,...
The ATLAS experiment at the Large Hadron Collider (LHC) is currently preparing to upgrade current inner tracking detector with a new all-silicon Inner Tracker, ITk. This will be made of five Pixel layers and four outer Strip layers. building blocks ITk strip barrel are staves.
