The Extreme Light Infrastructure ERIC (ELI ERIC) is the world’s largest and most advanced high-power laser research infrastructure. As an international user facility dedicated to multi-disciplinary science, ELI provides access to world-class high-power, high-repetition-rate laser systems and enables cutting-edge research, as well as breakthrough technological innovations. The ELI ERIC operates as a single multi-site organization with two complementary facilities specialized in different fields of research with extreme light: ELI Beamlines in Dolní Břežany (Czech Republic) and ELI ALPS in Szeged (Hungary).

ELI Beamlines Facility operates four cutting-edge high-power femtosecond laser systems reaching unprecedented intensities. The operational laser systems make unique femtosecond sources of X-rays and accelerated particles available to scientific users for pioneering research in physical, chemical, materials, life and medical sciences as well as physics of dense plasmas, warm dense matter, and laboratory astrophysics. The ELI Beamlines Facility employs over 350 researchers, engineers and other professionals from more than 38 countries.

In our team we have the following position available:

PhD Position – Effects of Prepulses on Laser-Driven Ion Acceleration (320)

High-power laser–matter interactions are strongly influenced by the presence of prepulses, which can lead to the formation of preplasma and significantly affect ion acceleration mechanisms. Understanding and controlling these effects is essential for improving the stability, reproducibility, and performance of laser-driven ion sources.

The Department 87 (Ion Acceleration and Application of High Energy Particles) is responsible for the development and operation of the ELIMAIA (ELI Multidisciplinary Applications of laser-Ion Acceleration) beamline, including the ELIMED section dedicated to medical and multidisciplinary applications. The team is actively engaged in R&D activities aimed at improving laser-driven ion acceleration, developing advanced diagnostics and targetry, and investigating fundamental plasma physics.

Within this context, we are seeking a highly motivated PhD student to investigate the effects of prepulses on target preplasma formation and ion acceleration dynamics. The project will combine theoretical modeling, numerical simulations, and experimental validation at ELI Beamlines, in particular at the ELIMAIA beamline.

Job description:

  • Investigation of prepulse effects on preplasma formation and their impact on laser-driven ion acceleration mechanisms
  • Development and execution of hydrodynamic and particle-in-cell (PIC) simulations (e.g. FLASH, SMILEI)
  • Support and participation in experimental campaigns at ELI Beamlines, including diagnostics and data acquisition
  • Analysis and interpretation of experimental and simulation data
  • Presentation of results at internal meetings, international conferences, and in peer-reviewed publications

Requirements:

  • Master’s degree in Physics, Plasma Physics, or related field
  • Knowledge of laser–matter interaction and ion acceleration physics
  • Experience with numerical simulation tools (hydrodynamic or PIC codes such as FLASH, SMILEI, or similar)
  • Familiarity with data analysis tools (Python, Matlab, or similar)
  • Interest in combining simulations and experimental work
  • Proactive, team-oriented attitude with good communication skills
  • Good command of English, both written and spoken

Additional experience is an advantage:

  • Experimental work in laser–plasma or accelerator laboratories
  • Monte Carlo simulations
  • Data acquisition systems
  • Advanced data analysis

We offer:

  • Hands-on laboratory experience in a unique international scientific institution
  • Extended stays at partner laboratories in Switzerland
  • Possibility of collaborating with detector development companies
  • Flexible working hours
  • Good working environment
  • Career growth, professional education
  • Meal allowance, pension contribution
  • Young and dynamic team
  • 5 weeks of vacation and 6 days of personal leave
  • Support of leisure time activities
