In preparation for the high-luminosity LHC (HL-LHC), the ATLAS detector will be upgraded with a new silicon-strip charged-particle tracking detector (ITk strip detector) to satisfy the radiation, granularity and timing requirements. The AMACStar (Autonomous Monitor and Control) is one of three ITk application-specific integrated circuits (ASICs). It is designed to monitor and control...
The High-Luminosity Large Hadron Collider (HL-LHC) is expected to deliver 10 times the integrated luminosity as the previous three runs combined, with approximately 200 inelastic collisions per bunch crossing. This large increase in pileup imposes significant challenges on the ATLAS Trigger and Data Acquisition system hardware electronics. To meet this challenge, the Global Trigger is designed...
Tau decays are notoriously difficult to detect because many particles decay with a similar signature. When searching for taus, capturing data from tau-lookalikes has been an ongoing problem, and previous global tau trigger algorithms have only had access to coarse granularity data from the calorimeters. The upgrade of the ATLAS Trigger and Data Acquisition system for the High-Luminosity Large...
The increased radiation environment and data rate for the High Luminosity Large Hadron Collider (HL-LHC) require upgrades to the readout electronics for the Muon Spectrometer (MS) electronics. In this talk, I will present ongoing irradiation studies of a custom-built front-end electronics board, the chamber service module (CSM), which is responsible for multiplexing data read out from...
The ATLAS experiment is currently preparing for an upgrade of the inner tracking detector for High-Luminosity LHC operation, scheduled to start in 2027. The new detector, known as the Inner Tracker or ITk, employs an all-silicon design with five inner Pixel layers and four outer Strip layers. The staves are the building blocks of the ITk Strip barrel layers. Each stave consists of a...
We are exploring Hough Transform (HT) algorithms in FPGAs to identify charged particle trajectories in the ATLAS detector at the HL-LHC. The Inner Detector of the ATLAS experiment measures the trajectories of charged particles in a uniform magnetic field. Our approach is to perform the Hough transformation pattern identification in two steps. The “first-stage” HT uses parameter space in phi0...
The inner tracking detector of the ATLAS experiment at CERN is currently preparing for an upgrade to operate in the High Luminosity LHC, scheduled for the late 2020s. A complete replacement of the existing Inner Detector of ATLAS is required to cope with the expected luminosity and radiation damage. The all-silicon Inner Tracker (ITk) design under construction composes a mixture of Pixel and...
