Oral

The next generation of silicon pixel detectors at high energy physics experiments sets unprecedented and extreme requirements to the microelectronic systems that are used to read out the sensors. Front-end integrated circuits will have to provide advanced analog and digital signal processing functions in high-density pixel readout cells, while handling huge data rates, operating at low power...

System Issues

Oral

The ALICE experiment underwent significant upgrades during the LHC Long Shutdown 2 (2019–2021), including the installation of the new Inner Tracking System (ITS2). ITS2 comprises seven layers with 12.5 billion pixels spanning 10 m², based on the ALPIDE CMOS Monolithic Active Pixel Sensors (MAPS), which offer an intrinsic spatial resolution of approximately 5 µm. Designed to handle Pb-Pb...

Oral

During the High Luminosity programme of the LHC collider (called HL-LHC), planned to start in 2030, the instantaneous luminosity will be increased from $\sim 2 \times 10^{34} cm^{-2}s^{-1}$ to an unprecedented figure of about $\sim 7.5 \times 10^{34} cm^{-2}s^{-1}$. This will allow the Compact Muon Solenoid (CMS) to collect up to $\sim 4000 fb^{-1}$ of integrated luminosity over a...

9. Up-to-date test beam results of ATLAS ITk Pixel sensors and modules

Oral

The ATLAS inner detector will be completely replaced with a new all-silicon tracking detector
(ITk) in 2026-28 to cope with the challenging conditions of the High Luminosity LHC.
The pixel detector will be located in the innermost part of the ITk detector. It will be
instrumented with 3D sensor technology it the innermost layer (L0), where a fluence up to 2
x 1016 neq/cm2 is expected, and...

54. Pixel column issue in the ATLAS ITk Pixel Modules

System Issues

Poster

Pixel modules are currently being built for the ATLAS ITk Pixel detector upgrade.

Since the preproduction phase, recurring chip malfunctioning was observed during electrical testing, that was bypassed by disabling some pixel core columns in the ITkPix readout chip.
This issue is therefore called the "core column issue" which is a direct disqualifier for a pixel module.
A concerning number...

56. Performance evaluation of a CMS Outer Tracker PS module before and after irradiation

System Issues

Oral

The LHC is about to enter the High Luminosity phase (HL-LHC) with a luminosity of 5-7.5×10^(34) cm^(-2)s^(-1) and a center-of-mass energy of 14 TeV. This phase will significantly increase the available data and impose tougher conditions on the detectors. To meet these new challenges, the CMS outer tracker will be updated with the new 2S and PS modules. Each module consists of a pair of silicon...
