About ELI Beamlines

ELI Beamlines research centre in Dolní Břežany is a part of pan-European infrastructure ELI (Extreme Light Infrastructure) representing a unique tool of support of scientific excellence in Europe by making available its capacities to the best scientific teams across the world. The aim of ELI Beamlines is to establish the most intensive laser system in the world and to operate it on a long-term basis. Due to ultra-high performances of 10 PW (1 petawatt = 
1,000,000,000,000,000 watts) and concentrated intensities of up to 1024 W/cm2, we can offer our users a unique source of radiation and beams of accelerated particles. The so called beamlines will enable ground-breaking research in the area of physics and science dealing with materials, but also in biomedicine and laboratory astrophysics and many other fields. ELI Beamlines is a part of the Institute of Physics of the Czech Academy of Sciences, and it was open in 2015. 

The Institute of Physics of the Czech Academy of Sciences is a holder of the HR Excellence in Research Award. It is awarded by the European Commission to institutions which put significant effort into improving their human resources strategy and ensuring professional and ethical working conditions. 

The radiation protection group addresses problems related to ionizing radiation from radiation protection to detector design by means of Monte Carlo simulations (primarily with FLUKA). In our team we are looking for a suitable candidate as: Radiation Physicist.

  • close and active cooperation with collaborating Institutes
  • possible participation in radiation protection operational activities

Required qualifications

  • university degree or research experience in physics, engineering, or other relevant fields
  • good knowledge of at least one Monte Carlo transport code (e.g. FLUKA, Geant4, MCNP, PHITS, etc.)
  • good knowledge of Linux/Unix OS
  • good knowledge of at least one high level programming language for physics (e.g. Fortran, C/C++, Python)
  • good knowledge of at least one scripting language
  • analytical and computational skills
  • ability to proficiently work both independently and in a team
  • ability to present and document the work done
  • fluency in English (both written and spoken)
  • availability to travel as required by necessity

Preferred experience/interest

  • radiation protection
  • radiation detectors and dosimetry
  • detector development
