As an applied physicist, you will be part of the RICH Detector strategic R&D activities and the LHCb RICH Upgrade project. This includes studies of novel single-photon detectors such as SiPMs (Silicon Photomultipliers) at cryogenic temperatures, calibrations of readout electronics in the sub-100 ps time domain and measurements of prototype optics for RICH detectors. Your work will combine hands-on activities (beam tests and measurements in the laboratory using picosecond pulsed laser illumination) with analysis of the performance of prototypes, simulation and the development of new detector designs and solutions.
Your responsibilities
- Actively participate in the LHCb RICH commissioning and electronics calibrations for the detector upgrade during LS3.
- Lead the qualification of prototype optics and RICH mirrors for future detector upgrades.
- Collaborate during beam tests and laboratory characterisation of single-photon detector prototypes, including data analysis.
- Engage with the module integration studies and system tests of SiPM sensors at cryogenic temperatures.
Your profile
- Demonstrated experience in applied physics.
- Proven understanding of HEP experiments and RICH detector designs.
- Experience in RICH detector tests (in laboratory and in test beams).
- Familiarity with readout electronics, DAQ systems and laboratory infrastructure.
- Proficiency in scientific writing and oral presentations.
Skills
- Strong analytical and problem-solving skills.
- Ability to work both autonomously and collaboratively in an international research environment.
- Extensive knowledge of laboratory equipment and techniques for single-photon detector measurements.
- Reliable, well-organised, and proactive approach to experimental work and calibration data analyses.
- Proficiency in programming languages such as C++, Python, and ROOT.
- Spoken and written English, with a commitment to learn French.
Eligibility criteria:
- You are a national of a CERN Member or Associate Member State.
- You have a professional background in Physics (or a related field) and have either:
- a Master's degree with 2 to 6 years of post-graduation professional experience;
- or a PhD with no more than 3 years of post-graduation professional experience.
- You have never had a CERN fellow or graduate contract before.
