What is ELI ?

ELI is a new Research Infrastructure (RI) of pan-European interest and part of the European ESFRI Roadmap.


The facility will be based on four sites. Three of them are presently being implemented in the Czech Republic, Hungary and Romania, with an investment volume exceeding 850 Mio. Euro, mostly stemming from the European Regional Development Funds (ERDF).

It is a laser facility that aims at hosting some the most intense lasers world-wide, develop new interdisciplinary research opportunities with light from these lasers and secondary radiation derived from them, and make them available to an international scientific user community.

After a 3-year Preparatory Phase (2008-2010) of the ELI project, the ELI Consortium was set up, and on 11 April 2013 became the ELI Delivery Consortium International Association (ELI-DC AISBL). The Association was established in order to promote sustainable development of the project, establishing partnerships and collaborations with national, European and international structures and organizations.

ELI-DC coordinates the transition from the implementation to the operation phase, leading to the creation of a European Research Infrastructure Consortium: ELI-ERIC.

ELI-DC supports the three pillars during the implementation phase, ensures the character of ELI as one unified pan-European project, conducts the negotiations towards the ELI-ERIC and prepares the conditions for the establishment of ELI’s fourth pillar, planned to push the frontiers of laser power by yet another order of magnitude into the sub-exawatt regime.

The scientific profiles of the ELI pillars will be complementary, and the operation of the Research Infrastructure, starting progressively form 2018, will be unified under one single legal umbrella of the ELI-ERIC.

The ELITRANS project

Enabling ELI’s transformation from ERDF - funded distributed implementation towards ERIC - governed unified operation

The goal of the ELITRANS project is to complement the final implementation stage of ELI - parallel to the completion of the three construction sites - by preparing and undertaking the back-transformation from three legally independent construction projects towards the governance, operation and financing under a single international legal entity, the ELI-ERIC.


The European Research Infrastructure Consortium (ERIC) is a legal framework created by the European Commission to allow the operation of Research Infrastructures of Pan-European interest.

  • ELI-Beamlines Facility

    In Dolni Brezhany, near Prague, Czech Republic, the ELI-Beamlines facility will mainly focus on the development of short-pulse secondary sources of radiation and particles, and on their multidisciplinary applications in molecular, biomedical and material sciences, physics of dense plasmas, warm dense matter, laboratory astrophysics. In addition, the pillar will uitilze its high-power, high-repetition-rate lasers for high-field physics experiments with focused intensities of about 1023 W/cm2, investigating exotic plasma physics, and non-linear QED effects. www.eli-beams.eu

  • ELI Nuclear Physics Facility

    In Magurele, Romania, the ELI Nuclear Physics (ELI-NP) facility will focus on laser-based nuclear physics. It will host two machines, a very high intensity laser, where beams from two 10 PW lasers are coherently added to get intensities of the order of 1023 - 1024 W/cm2, and a very intense, brilliant gamma beam which is obtained by incoherent Compton back scattering of a laser light off a brilliant electron beam from a conventional linear accelerator. Applications include nuclear physics experiments to characterize laser – target interaction, photonuclear reactions, and exotic nuclear physics and astrophysics.  http://www.eli-np.ro

  • ELI-Attosecond Facility

    The ELI Attosecond Light Pulse Source (ELI-ALPS) in Szeged, Hungary is establishing a unique facility which provides light sources between THz (1012 Hz) and x-ray (1018 - 1019 Hz) frequency range in the form of ultrashort pulses with high repetition rate. ELI-ALPS will be dedicated to extremely fast dynamics by taking snap-shots in the attosecond scale (a billionth of a billionth of second) of the electron dynamics in atoms, molecules, plasmas and solids. It will also pursue research with ultrahigh intensity lasers.   http://www.eli-alps.hu
