Role overview
The Global
Hardware Trigger is part of the upgrade to the Trigger and Data Acquisition that ATLAS plans to deploy for the High-Luminosity LHC programme (HL-LHC).
It is a custom hardware, real-time data processing and filtering system, currently under construction, that uses fine-granularity detector information and will employ advanced pattern recognition algorithms.
- The Global
- Hardware Trigger is part of the upgrade to the Trigger and Data Acquisition that ATLAS plans to deploy for the High-Luminosity LHC programme (HL-LHC).
- Your responsibilities
- Develop and maintain pipelines to streamline the end-to-end process of developing, optimising, and implementing ML algorithms into the Global firmware framework, and support the ATLAS Global community in using these pipelines.
- Strong track record in developing novel ML algorithms, especially in the context of particle physics experiments.
- Strong background in computational statistics.
Main responsibilities
- Your responsibilities
- Develop and maintain pipelines to streamline the end-to-end process of developing, optimising, and implementing ML algorithms into the Global firmware framework, and support the ATLAS Global community in using these pipelines.
- Contribute to Global hardware integration activities at CERN.
- Explore, develop, and optimise novel ML algorithms for Global, and play a leading role in developing the trigger menu and strategy for the start of the HL-LHC programme.
- Explore, develop, and optimise concepts of anomaly detection, trigger-level analysis, and data scouting in ATLAS using the Global system.
- Explore the potential and applicability of novel industry technologies (e.g., AMD AI Engines) to enhance the reach of the ATLAS Global system.
- This role includes team supervision responsibilities.
