Evolution of the electrical characteristics of the ATLAS ITk strip sensors with HL-LHC radiation exposure range / ATLAS Collaboration
In 2021, the ATLAS collaboration started the production phase of the new Inner-Tracker (ITk) strip sensors, so-called ATLAS18, that should be able to withstand the extreme radiation conditions expected for the forthcoming High-Luminosity Large Hadron Collider (HL-LHC) upgrade. The new all-silicon ITk detector will reach unprecedented accumulated fluences and ionizing doses, caused by the increase of the total integrated luminosity. [...]

Evolution of the electrical characteristics of the ATLAS18 ITk strip sensors with HL-LHC radiation exposure range / ATLAS Collaboration
The objective of the study is to evaluate the evolution of the performance of the new ATLAS Inner-Tracker (ITk) strip sensors as a function of radiation exposure, to ensure the proper operation of the upgraded detector during the lifetime of the High-Luminosity Large Hadron Collider (HL-LHC). [...]

Low dose gamma irradiation study of ATLAS ITk MD8 diodes / ATLAS Collaboration
Silicon strip detectors developed for the Inner Tracker (ITk) of the ATLAS experiment will operate in a harsh radiation environment of the HL-LHC accelerator. The ITk is thus designed to endure a total fluence of 1.6×1015 1 MeV neq/cm2 and a total ionizing dose (TID) of 66 Mrad in the strip detector region. [...]

ATLAS ITk Strip Sensor Quality Control and Review of ATLAS18 Pre-Production Sensor Results / ATLAS Collaboration
With the upgrade of the LHC to the High-Luminosity LHC (HL-LHC), the Inner Detector will be replaced with the new all-silicon ATLAS Inner Tracker (ITk) to maintain tracking performance in a high-occupancy environment and to cope with the increase in the integrated radiation dose. [...]

Gamma irradiation of ATLAS18 ITk strip sensors affected by static charge / ATLAS Collaboration
Construction of the new all-silicon Inner Tracker (ITk), developed by the ATLAS collaboration to be able to track charged particles produced at the High-Luminosity LHC, started in 2021 and is expected to continue until 2028. The ITk detector will include ~20,000 highly segmented and radiation hard n+-in-p silicon strip sensors, which are being manufactured by Hamamatsu Photonics. [...]

Analysis of humidity sensitivity of silicon strip sensors for ATLAS upgrade tracker, pre- and post-irradiation / ATLAS Collaboration
The ATLAS collaboration is working on a major upgrade of the Inner-Tracker, able to withstand the extreme operational conditions expected for the forthcoming High-Luminosity Large Hadron Collider (HL-LHC) upgrade. During the prototyping phase of the new large area silicon strip sensors, the community observed a degradation of the breakdown voltage (down to 200-500 V from >= 1 kV in bias voltage) when the devices with final technology options were exposed to high humidity, recovering the electrical performance prior to the exposure after a short period in dry conditions [J.

ANALYSIS OF THE QUALITY ASSURANCE RESULTS FROM THE INITIAL PART OF PRODUCTION OF THE ATLAS18 ITK STRIP SENSORS / ATLAS Collaboration
The production of strip sensors for the ATLAS Inner Tracker (ITk) started in 2021. During this time, a Quality Assurance (QA) program is being carried out continuously, by using specific test structures, in parallel to the Quality Control (QC) inspection of the sensors. [...]

Characterization of the Polysilicon Resistor in Silicon Strip Sensors for ATLAS Inner Tracker as a Function of Temperature, Pre- And Post-Irradiation / ATLAS Collaboration
The high luminosity upgrade of the Large Hadron Collider, foreseen for 2029, requires the replacement of the ATLAS Inner Detector with a new all-silicon Inner Tracker (ITk). The expected total integrated luminosity of $4000\, \mathrm{fb}^{−1}$ means that the strip part of the ITk detector will be exposed to the total particle fluences and ionizing doses reaching the values of $1.6 \cdot 10^{15}$ $1\, \mathrm{MeV}$ $\mathrm{n_{eq}/cm^2}$ and $0.66\, \mathrm{MGy}$, respectively, including a safety factor of $1.5$.
