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...
Abstract The objective of the study is to evaluate evolution performance new ATLAS Inner-Tracker (ITk) strip sensors as a function radiation exposure, ensure proper operation upgraded detector during lifetime High-Luminosity Large Hadron Collider (HL-LHC). Full-size ITk Barrel Short-Strip (SS) with final layout design, ATLAS18SS, have been irradiated neutrons and gammas, confirm results obtained prototypes miniature development phase. irradiations cover wide range fluences doses that will...
Abstract Construction of the new all-silicon Inner Tracker (ITk), developed by ATLAS collaboration to be able track charged particles produced at High-Luminosity LHC, started in 2020 and is expected continue till 2028. The ITk detector will include 18,000 highly segmented radiation hard n+-in-p silicon strip sensors (ATLAS18), which are being manufactured Hamamatsu Photonics. Mechanical electrical characteristics measured upon their delivery several institutes participating a complex Quality...
Abstract The bulk damage of p-type silicon detectors caused by high doses gamma irradiation has been studied. study was carried out on three types n + -in-p diodes with comparable geometries but different initial resistivities. This allowed to determine how parameters studied samples influence radiation-induced changes in the measured characteristics. were irradiated a Cobalt-60 source total ionizing ranging from 0.50 up 8.28 MGy, and annealed for 80 minutes at 60 °C. Geant4 toolkit...
The production of strip sensors for the ATLAS Inner Tracker (ITk) started in 2021. Since then, a Quality Assurance (QA) program has been carried out continuously, by using specific test structures, parallel to Control (QC) inspection sensors. QA consists monitoring sensor-specific characteristics and technological process variability, before after irradiation with gammas, neutrons, protons. After two years, half full volume reached we present an analysis parameters measured as part process....
The new all-silicon Inner Tracker (ITk) is being constructed by the ATLAS collaboration to track charged particles produced at High-Luminosity LHC. outer portion of ITk detector will include nearly 18,000 highly segmented and radiation hard silicon strip sensors (ATLAS18 design). Throughout production 22,000 sensors, are subjected a comprehensive suite mechanical electrical tests as part Quality Control (QC) program. In large fraction batches delivered date, high surface electrostatic charge...
The ATLAS experiment will replace its existing Inner Detector with the new all-silicon Tracker (ITk) to cope operating conditions of forthcoming high-luminosity phase LHC (HL-LHC). outer regions ITk be instrumented ∼18000 ATLAS18 strip sensors fabricated by Hamamatsu Photonics K.K.

With launch full-scale sensor production in 2021, community has undertaken quality control (QC) testing these ensure compliance mechanical and electrical specifications agreed HPK. is conducted at seven QC...
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. Radiation hard n + -in-p micro-strip silicon sensors were developed by Tracker strip collaboration and are produced Hamamatsu Photonics K.K. Production total amount 22000 has started 2020 will continue until 2025. sensor responsibility monitor quality fabricated devices performing detailed measurements individual...
Abstract The successful pre-production delivery of strip sensors for the new Inner Tracker (ITk) upgraded ATLAS detector at High Luminosity LHC (HL-LHC) CERN was completed and based on their performance full production has commenced. overall period is anticipated to last 4 years complete approximately 22000 required ITk. For Quality Assurance (QA), a number test structures designed by collaboration, along with large area diode miniature version main sensor, are produced in every wafer...
Abstract During the prototyping phase of new ATLAS Inner-Tracker (ITk) strip sensors, a degradation device breakdown voltage at high humidity was observed. Although temporary, showing fast recovery in dry conditions, study influence on sensor performance critical to establish counter-measures and handling protocols during production testing order ensure proper upgraded detector.
