Sources of 14 MeV Neutrons
60
A method for measuring neutron-charged particle coincidences from
the 14.4 MeV neutron-induced reactions has been developed in 1969–1970 in
the Nuclear Reaction Laboratory, IRB, Zagreb, Croatia (Miljanic etal. 1969;
Valkovic etal. 1969, 1970). Detection of associated alpha particles has been used
to “electronically collimate” the produced neutron beam in order to reduce the
experimental background. In the performed measurements the n+d → n+n+p
reaction has been studied by the coincidence detection of the outgoing proton
and neutron. As the neutron source a Cockcroft–Walton accelerator has been
used.
