Abstract. The urgency of design and construction of a 14 MeV dedicated neutron
source which is absolutely needed to perform the material development and
testing for future fusion power reactor is widely recognised. First of all,
such a source makes it possible to collect information about mechanical,
electrical and other properties of structural materials for DEMO
design. About 10 years ago, material scientists have formulated criteria for
the required parameters of such as source. In particular, 14 MeV neutron
flux density was determined as 2
MW/m2. However, in recent years,
this requirement was strengthened till 4-5
MW/m2. The paper presents
different approaches to the problem how this increased neutron flux can be
provided. It is shown that on the basis of the gas dynamic trap (GDT)
concept the required neutron flux density can be achieved.
