The Office of Science in the Department of Energy invites interested parties to provide input on potential technological approaches to meet the needs of the Fusion Energy Sciences (FES) program for a Fusion Prototypic Neutron Source (FPNS) and on potential ways to accelerate the construction and delivery of such a facility, including partnerships with the private sector.


The demonstration of fusion energy will require mastering materials science and performance issues associated with materials degradation due to bombardment by energetic fusion neutrons. This requirement underscores the critical need for a FPNS, which is aimed at filling this gap and will help enable the development of next-generation, high-performance materials for future fusion devices.
