Applied Physicist for CMS Inner Detectors (EP-CMS-ID-2026-153-LD)

Introduction:

You will develop algorithms, FPGA firmware, and data acquisition systems for CMS online luminosity measurement, beam monitoring, and Tracker calibration for the High Luminosity LHC, and coordinate such developments.

This involves Integrating and commissioning back-end systems for luminosity and tracking detectors, enabling real-time data processing and precision luminosity measurements.

Functions:

• Develop, deploy, and maintain firmware and real-time algorithms for back-end electronics across multiple CMS board platforms, including systems for the Fast Beam Conditions Monitor (FBCM), Inner and Outer Tracker online luminosity, to support luminosity measurement, beam monitoring, and lumi-trigger generation.
• Validate front-end detectors (including FBCM and Tracker modules) and back-end electronics through laboratory testing, ensuring end-to-end system performance from detector to data output.
• Execute detector functional tests during detector integration at the Tracker Integration Facility, ensuring system readiness prior to installation.
• Organise and lead test campaigns, including preparatory activities, on-site coordination of participants, and systematic validation of hardware, firmware, software and detector response.
• Lead studies of detector efficiency, calibration quality, and operational stability, through measurements and simulations.
• Coordinate technical interfaces across detector, trigger, timing, and data acquisition domains to ensure system integration.
• Supervise and mentor students and fellows, including recruitment and structured technical guidance.
• Anticipate upcoming technical and operational needs, structuring workflows, preparing infrastructure, and engaging with collaborating institutes to ensure continuity of operations.
