The Extreme Light Infrastructure (ELI) is set to launch the 4th ELI User Call on 25 March with an open Call period until 29 April. This Call will continue to support a wide range of experiments, leveraging ELI’s state-of-the-art equipment at ELI ALPS and ELI Beamlines. Researchers and scientists worldwide are invited to submit their proposals which will be evaluated based on scientific excellence by an international peer-review panel.

preliminary list of the equipment available in the upcoming call is published with this announcement. The full set of parameters and technical information are being revised, taking into account ongoing commissioning work, and will be made available on the User Portal by 25 March. 

With the ELI User Programme evolving, efforts to streamline access and support the users are ongoing. As part of this, ELI has taken a significant step forward by establishing a centralised User Office. The User Office is coordinating user access across the ELI ERIC Facilities, ensuring that researchers have a single point of contact for their proposals, questions, and needs. The aim is to offer a uniform user experience and support ground-breaking research. Scientists interested in submitting a proposal are strongly encouraged to contact the ELI User Office or technical contacts in advance. 

Looking Ahead: Future Calls and Events

ELI will announce bi-annual User Calls in Spring and Autumn. This pattern underscores the commitment to making the facilities available to a growing number of researchers for scientific experiments. Accordingly, the 5th Call is expected to launch at the from 25 September until 29 October 2024.
