5. Neutron source requirements
Along the time, it has been widely recognized that a fusion-like neutron source is needed for fusion materials qualification both for DEMO and the power plant development
The requirements are to produce fusion-like neutrons
Intensity large enough to allow accelerated testing,
Damage level above the expected operational lifetime,
Irradiation volume large enough to allow the characterization of the macroscopic properties of the materials of interest required for the engineering design
The most feasible approach based on Li(d,xn) sources
The IFMIF project since 90´s

7. What is IFMIF-DONES? IFMIF-DONES (Demo-Oriented Neutron Source)
It is the minimum neutron source required to fulfill the materials fusion-like irradiations needs of DEMO

Main technical characteristics:
Based on IFMIF Preliminary Engineering Design simplified as much as possible

23. Summary
A fusion-like neutron source is needed as soon as possible for DEMO design and IFMIF-DONES is the proposed European alternative to be implemented in the near future
IFMIF-DONES design is based on IFMIF design evolved to take into account a reduced scope and results obtained during the prototyping phase
Preliminary Engineering Design Report were released early Present design activities are site specific (Granada-Spain-)
A “Start of construction” decision should be taken as soon as possible
