Postdoctoral Fellow – Cryogenics (IV-100)

ELI Beamlines research center in Dolní Břežany is 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 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 up to 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 part of the Institute of Physics of the Czech Academy of Sciences, and it was opened 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 ELIMAIA (ELI Multidisciplinary Application of laser-Ion Acceleration) user beamline has been recently installed by the Research Programme 3 (Particle Acceleration) team, along with its key system ELIMED (ELI MEDical Applications) for ion beam transport and dosimetry. The mission of ELIMAIA is to provide stable and well-characterized beams of ions for users interested in exploring a wide range of applications.

High repetition rate laser operation (up to 10Hz) is very challenging in terms of target fabrication, a delivery system including positioning, alignment, and real-time target characterization. For this reason, liquid and cryogenic targets are currently being considered for operation at a high repetition rate as both refreshable and debris.

The goal of the research is to study laser-driven ion acceleration using liquid and cryogenic jet target systems, provide experimental measurements of various target parameters; assist in the characterization of the accelerated ion bunches in terms of energy, current, and divergence.

For this purpose, we are seeking a suitable candidate able to work in a R&D project as:

Postdoctoral Fellow – Cryogenics (IV-100)

Main responsibilities include:

• R&D that focus on cryogenic jet target systems
• operation of the cryogenic target system in preparation of commissioning experiments and later on user experiments
• cooperation with RP3 researchers for design and development of various diagnostics
• installations and maintenance of various technologies in the experimental hall dedicated to ion acceleration, including technical support and coordination activities with ELI technicians and ELI safety team
• general user support during experiments with ELIMAIA

• PhD in physics or physical-engineering or equivalent research experience
• basic knowledge of cryogenic techniques
• knowledge in programming software (Matlab, Pyton, LabView or any other) is considered an advantage
• fluency in English (both oral and written)
• good communication skills
• working experience obtained in research, scientific, or academic institution is an advantage

• the opportunity to participate in this unique scientific project
• competitive and motivating salary
• flexible working hours
• nice working environment
• career growth
• lunch vouchers, pension contribution and 5 sick days
• support of leisure time activities

Applications, containing CV, cover letter, contacts of references, and any other material the candidate considers relevant, should be sent to Mrs. Jana Ženíšková, HR specialist ([email protected] , +420 - 601560322).
