Applied physicist for e+e- detector development (fine-grained calorimetry).


The PH Department carries out basic research in the field of experimental and theoretical particle physics. It aims at providing a stimulating scientific atmosphere and remains an important reference centre for the European physics community. It contributes to the education and training of young scientists.


Within the physics department you will join the Detector Technology (DT) group, which is in charge of the development, construction and maintenance of particle detectors for the different experiments at CERN. As a member of the DT group, you will join the Linear Collider Detector (LCD) project. The LCD detector development activities focus on forefront vertex and tracker R&D as well as compact fine-grained calorimetry R&D for an experiment at CLIC, a future  high-energy e+e- collider under development, while exploiting synergies with other projects, such as the detector upgrades for HL-LHC and detector R&D for other experiments.



As Applied physicist for e+e- detector development, you will perform multiple tasks in support of the group's activities. Emphasis will be on the development of fine-grained calorimetry, including detector simulations, laboratory tests, beam tests and the analysis of test data. Additional tasks will cover broader engagements in detector modelling, event reconstruction and assessment of test results. You will engage in related facilitating, supervisory and coordinating roles in the framework of the various collaborations in which the group is involved.


More specifically, this entails:


  • Laboratory studies and beam tests with emphasis on detector modelling, detailed assessment of calibration methods and analysis of test results in the domain of compact fine-grained calorimetry.
  • Participation in other detector R&D and detector optimisation studies pursued within the LCD project, taking CLIC precision requirements, the experimental conditions and prospective detector technologies into account.
  • Presentation of status reports and results at collaboration meetings and conferences, and the documentation of the studies in detailed technical notes and scientific publications.
  • Support, supervisory and coordination tasks in the above domains to ensure a smooth work environment for a wider community of institutes collaborating with the PH-DT group and the Linear Collider Detector project.
  • Participation in maintaining active links and exploiting synergies with other projects, such as HL-LHC (e.g. CMS HGC) and FCC, in the domain of detector development.


Qualification required

Master's degree in the field of Physics and/or PhD/doctorate in the field of particle physics, or equivalent.


Experience and competencies

The experience required for this post is:


  • Extensive experience in the analysis of test results from detector prototyping, with particular emphasis on calibration issues, statistical analysis of large data sets and the assessment of systematic effects.
  • Demonstrated experience in the development and use of simulation and event reconstruction tools commonly used in particle physics, with emphasis on Geant4-based detector modelling in the field of calorimetry, preferably implemented in the linear collider software framework.
  • Demonstrated expertise in the subject of electromagnetic and hadronic shower development in calorimetry.
  • Demonstrated ability to efficiently produce detailed documentation in both oral and written form.
  • Experience in individual supervisory roles


The technical competencies required for this post are:


  • Detector performance simulation and analysis.
  • Calorimetry methods and techniques.
  • Use of Scientific and Engineering software packages: detector simulation and event reconstruction software (e.g. Geant4, ILCSoft).
  • Coaching: demonstrated ability to efficiently fulfil collaboration wide support or coordination roles.


The behavioural competencies required for this post are:


  • Achieving results: delivering high quality work on time and fulfilling expectations; being rigorous and producing quality results at first attempt; driving work / projects along and seeing them through to their conclusion.
  • Working in teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities; sharing and letting others participate in own work/project; encouraging team development.
  • Learning and sharing knowledge: keeping up-to-date with developments in own field of expertise and readily absorbing new information; sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer.
  • Communicating effectively: delivering presentations in a structured and clear way; adjusting style and content to the audience; responding calmly and confidently to questions; ensuring that information, procedures and decisions are appropriately documented; expressing opinions, ideas and suggestions with conviction and in a logical/structured manner; keeping to the point.


The language competencies required are:


  • English: spoken and written, with the ability to draw up technical specifications and/or scientific reports, and/or to make oral presentations.
  • The ability to understand and speak French in professional contexts would be an advantage.
