NEPHEWS in Detail

The project will deliver access to the world-class collective of Europe’s premiere open advanced neutron (N), synchrotron (SR) and free-electron laser (FEL) complementary research infrastructures (RI), to promote curiosity driven excellence in research.


In NEPHEWS the RI institute in a novel approach jointly with their 40k+ user base of scientists through Users Organisations to provide a user-driven access program targeting new and non-expert communities, with a focus on Widening countries, Ukraine and Africa, a priority. The bottom-up User-to-User-oriented approach aims to build an integrated European RI landscape involving LEAPS and LENS consortia and their European scientific user communities.


NEPHEWS is unique in many aspects:

  • It is a user driven project which brings together the two “photon” and “neutron” European users organisations of the “PaN” research infrastructure facilities ESUO and ENSA.
  • It brings together the LEAPS and LENS RI in a broad combined access programme for excellent curiosity driven science for the first time.
  • It seeks to broadens the use of the PaN RI opening these to new users, new and less well supported user communities and will do so through specific outreach and twinning opportunities for users new to techniques as well as early stage researchers.
  • It seeks to make progress towards policy impact to advocate for nationally funded programs to help scientists access extra-national open RI facilities in other countries, when funding of the users travel and subsistence is an issue.


NEPHEWS is focused on accomplishing several key goals:

  • Enhance trans-national cooperation and knowledge distribution, particularly from scientifically advanced regions to less active ones.
  • Remove barriers to accessing world-class accelerator-based light sources in Europe and the Middle East.
  • Educate new users on effectively utilizing synchrotrons, neutrons, and FELs.
  • Collaborate on continuously advancing technology to maintain cutting-edge facilities.
  • Raise awareness about the value of large research infrastructures in advancing European knowledge and addressing global societal challenges.
  • Utilize the potential of Early Stage Researchers (ESRs) and scientists in scientifically less active countries or regions lacking large-scale RIs.

What is NEPHEWS?

Project Name:
Neutrons and Photons Elevating Worldwide Science
Project Acronym:
Project Number:
Horizon Europe
January 2024 – December 2026
18 Partners, 5 associated partners
Project Coordinator:
National Synchrotron Radiation Centre SOLARIS – Jagiellonian University, Kraków, Poland

Who is involved?

The NEPHEWS Consortium includes 21 national and international RI facilities (9 synchrotrons, 6 neutrons, and 6 FELs) in Europe and the Middle East, along with 2 user organizations.


The work is organized into 18 Work Packages, covering various networking, training, and Transnational Access Activities.


NEPHEWS offers:

  • 135 twinning experiments with expert users (TWINNING Programme)
  • 451 user experiments across European RI facilities (TNA Programme)
  • 24 new and non-expert users receiving in-depth, hands-on expert training (ESR Programme)


These initiatives are supported by virtual access, workshops, schools, and proposal writing assistance. All efforts aim to build expertise, foster collaborations, and widen user access across the European Research Area (ERA).


What we offer

We provide comprehensive support that includes access to advanced infrastructure, connecting new users with experienced research groups and internships at leading research centers across Europe.


Who we are

NEPHEWS collaborates with the two largest and most advanced research infrastructure consortia within the European Research Area. Together with user community representatives, we provide curiosity-driven, trans-national access to users.
