ATLAS silicon module assembly and qualification tests at IFIC Valencia

ATLAS experiment, designed to probe the interactions of particles emerging out of proton proton collisions at energies of up to 14 TeV, will assume operation at the Large Hadron Collider (LHC) at CERN in 2007. This paper discusses the assembly and the quality control tests of forward detector modules for the ATLAS silicon microstrip detector assembled at the Instituto de Fisica Corpuscular (IFIC) in Valencia. The construction and testing procedures are outlined and the laboratory equipment is briefly described. Emphasis is given on the module quality achieved in terms of mechanical and electrical stability.Comment: 23 pages, 38 EPS figures, uses JINST LaTeX clas

Diagnostic Analysis of Silicon Strips Detector Readout in the ATLAS Semi-Conductor Tracker Module Production

The ATLAS Semi-Conductor Tracker (SCT) Collaboration is currently in the production phase of fabricating and testing silicon strips modules for the ATLAS detector at the Large Hadron Collider being built at the CERN laboratory in Geneva, Switzerland. A small but relevant percentage of ICs developed a new set of defects after being mounted on hybrids that were not detected in the wafer screening. To minimize IC replacement and outright module failure, analysis methods were developed to study IC problems during the production of SCT modules. These analyses included studying wafer and hybrid data correlations to finely tune the selection of ICs and tests to utilize the ability to adjust front-end parameters of the IC in order to reduce the rejection and replacement rate of fabricated components. This paper will discuss a few examples of the problems encountered during the production of SCT hybrids and modules in the area of ICs performance, and will demonstrate the value of the flexibility built into the ABCD3T chip

The performance and operational experience of ATLAS Semiconductor Tracker in Run-2 at LHC

The performance of ATLAS SemiConductor Tracker (SCT) in Run-2 at Large Hadron Collider (LHC) has been reviewed during the current long shutdown. The LHC successfully completed its Run-2 operation (2015-2018) with a total integrated delivered luminosity of 156 fb−1 at the centre-of-mass pp collision energy of 13 TeV. The LHC high performance provide us a good opportunity for physics analysis. It came with high instantaneous luminosity and pileup conditions that were far in excess of what the SCT was originally designed to meet. The first significant effects of radiation damage in the SCT were also observed during Run-2. This talk will summarise the operational experience and performance of the SCT during Run-2, with a focus on the impact and mitigation of radiation damage effects

The LHC successfully completed its Run-2 operation (2015-2018) with a total integrated delivered luminosity of 156 fb$^{-1}$ at the centre-of-mass $pp$ collision energy of 13 TeV. The LHC high performance provides a good opportunity for physics analysis. The instantaneous luminosity and pileup conditions were far in excess of what the SCT was originally designed to meet. This document will summarise the operational experience and performance of the SCT during Run-2, with a focus on the impact and mitigation of radiation damage effects, which were observed in Run-2

Operation and performance of the ATLAS Semi-Conductor Tracker

As reported in the previous VERTEX conference, the SCT successfully re-started operations in LHC Run-3 (2022-2025). The operation condition of SCT from LHC Run-3 is the same as those in Run-2 which came with high instantaneous luminosity and pileup conditions that were far in excess of what the SCT was originally designed to meet. This talk will summarise the operational experience and performance of the SCT from the recent SCT operations in Run-3. Also the observation and prospect of the radiation damage on SCT silicon strip sensors will be presented

The operational experience and performance of the ATLAS SCT during Run-2 and LS2, and the first impression from Run3 operations.

Readout Electronics Tests and Integration of the ATLAS Semiconductor Tracker

The SemiConductor Tracker (SCT) together with the Pixel detector and the Transition Radiation Tracker (TRT) form the central tracking system of the ATLAS experiment at the LHC. It consists of single-sided microstrip silicon sensors, which are read out via binary ASICs based on the DMILL technology, and the data are transmitted via radiation-hard optical fibres. After an overview of the SCT detector layout and readout system, the final-stage assembly of large-scale structures and the integration with the TRT is presented. The focus is on the electrical performance of the overall SCT detector system through the different integration stages, including the detector control and data acquisition system. I
