Accelerator driven p(37)-D2O fast neutron source at NPI Řeř

In the article, the fundamental information on the neutron production in the D(p,n)2p reaction is summarized, and the measurements at research facilities dealing with such types of source are described. The details about the experimental study of p + D
2
and p + D

O source reaction with a broad neutron spectrum up to 34 MeV is characterized, and the neutron field determined by the multi-foil activation technique validated against the Monte Carlo MCNPX calculations is presented. The research programs realized in this neutron field, commonly used for experimental simulation of the IFMIF (International Fusion Material Irradiation Facility) spectrum, are outlined.
