Applied Physicist - LHCb Electronics Integration

Applied Physicist - LHCb Electronics Integration

CERN - European Organization for Nuclear Research

Geneva, Switzerland

What you'll do

As an applied physicist, you will support the design, integration, and commissioning of front-end electronics systems across LHCb subdetectors (VELO, RICH, CALO) for the LHCb Upgrade II project, targeting demanding timing requirements. Your work will combine hands-on technical development – system integration, calibration, and module R&D – with harmonising timing approaches across subdetectors, working closely with CERN Electronics and Detectors Technology support groups, and the LHCb Online team.

Your responsibilities

• Support system-level integration and commissioning of the electronics chain, working with subdetector experts and the LHCb Online team.
• Develop control software and calibration procedures for detectors in the LHCb electronic control system.
• Provide project-based support for PCB development, mechanical/cooling integration, and electronics infrastructure (LV, HV).
• Coordinate across LHCb subdetectors (VELO, RICH, CALO) to harmonise fast timing implementation at the front-end level, liaising with CERN Electronics support experts and the LHCb electronics coordinator.
• Contribute to R&D on module integration and cooling.

Your profile

• Experience of commissioning and operation of detectors of large particle physics experiments.
• Experience in the whole signal treatment chain from front-end electronics to readout and control electronics, including high-speed signal processing and transmission. Experience of the HL-LHC experiments common electronic components (lpGBT, VTRx+, bPOLs, etc.) is a plus.
• Experience with fast timing detectors and precision timing systems.
• Experience in PCB design and module prototyping.
• Experience in developing and testing detector modules, including mechanical integration of the electronics and cooling.
• Good knowledge of low voltage and high voltage distribution systems for large particle detectors.
• PhD or equivalent relevant experience in the field of Physics or Electronics or a related field.

Your skills

• Simulation, design and development of (parts of) detectors.
• Testing and validation of detectors.
• Assembly and integration of detectors.
• Layout of electronic circuit boards.
• Organisation, planning and control.
• Has a structured and organised approach towards work; is able to set priorities and plan tasks with results in mind.
• Builds and maintains constructive and effective work relationships.
• Takes initiative beyond regular tasks and makes things happen.
• Readily absorbs new techniques and working practices; proposes new or improved ways of working.
• Presents information accurately and objectively.
• Spoken and written English, with a commitment to learn French.
