ELENA is open to new members in Europe
which engage in the field of low energy
accelerator-based neutron sources.

The ELENA association has been created on September 10th 2020 to promote cooperation between European laboratories or private companies or individuals working in the field of neutron sources based on an accelerator and a low energy reaction to produce neutrons. Members of the association agree to cooperate and initiate collaborations, conferences, workshops and meetings in order to create an effective ecosystem for research and applications in all areas of science and industry around these neutron sources.
