Radiation Effects Physicist/Engineer in the Engineering Department (EN), Sources, Targets and Interactions Group (STI).

You will join:

  • The Engineering (EN) Department that provides engineering competencies, infrastructure systems and technical coordination for the world's largest particle accelerator complex and its experimental facilities.
  • The Sources, Targets and Interactions (STI) Group which has the mandate to study the interactions of beam with matter, applying its know-how to particle generation and particle interception. The group is also responsible for developing and maintaining the FLUKA Monte Carlo code and for providing formal training and support to its users in the accelerator community and to the experiments worldwide. The group is a member of the n_TOF and UA9 collaborations.


Functions:

Following an initial period of training within the EN-STI Group, you will be part of the team responsible for the work on radiation damage qualification in the CERN accelerator sector. This involves in particular electronic components or systems of the LHC and injector chain equipment, as well as other non-beam intercepting materials used in high radiation areas.

In close collaboration with corresponding equipment groups, the team defines, implements and analyses the necessary radiation hardness assurance approach, focusing especially on qualification processes within CERN and all related support activities (calculations, modelling, monitoring, testing, facilities, etc.).

In particular, you will focus on the analysis of the operational modes of the LHC and their impact on radiation levels in the LHC, you will be responsible for the calibration and quality assurance of CERN's in-house radiation test facilities, being capable of associating their relevant radiation effects quantities with those present in the application cases. You will be analysing present, and defining future, radiation levels for the CERN accelerator chain, focusing on the impact on the corresponding radiation qualification strategy and respective monitoring requirements.

In this role, you will be in close contact with the radiation effects community, maintaining and extending existing international collaborations relevant to the accelerator technology sector and promoting CERN's role in the domain.

Qualification required:

Master's degree in the field of applied physics, or equivalent.


The experience required for this post is:

  • Knowledge of radiation interaction with matter and experience in corresponding Monte Carlo codes (FLUKA, Geant4).
  • Demonstrated experience in radiation testing of electronic components, including test preparation, measurement campaign, data analysis and reporting. Background in testing at different facility types is an asset.
  • Extensive knowledge of radiation effects on electronics, including the basic physical mechanisms involved.
  • Experience in radiation hardness assurance approaches, both at component and system level.
  • Experience in detection of radiation levels relevant to radiation damage.
  • Experience in radiation test facility operation and calibration techniques.
  • Experience in accelerator operation or in accelerator based beam tests would be an asset.

The technical competencies required for this post are:

  • Physics simulation: HEP Phenomenology, Monte-Carlo techniques, knowledge and use of event generators (Pythia, Herwig).
  • Knowledge of radiation effects on electronics and mitigation techniques: effects of ionizing and non-ionizing radiation on electronics, single event effects, mitigation techniques.
  • Neutronics.
  • Knowledge of nuclear reactions.
  • Radiation protection & radiation safety: knowledge of measurement techniques for ionising radiation.

The language competencies required are:

  • Spoken and written English: ability to understand and speak French in professional contexts.
  • Ability to draw-up technical specifications and/or scientific reports and to make oral presentations in at least one of the two languages.
