Description
At the Nuclear Physics Institute at the laboratory of Fast Neutron Generators, a new neutron
collimator was recently constructed. Simultaneously a new neutron converter coupled to the
collimator was constructed and successfully tested last year. Collimated beams of fast
neutrons bringing new experimental possibilities especially for on-beam measurements with
semiconductor detectors. Motivated by the development of future fission and fusion energy
projects the nuclear data measurements of cross-sections for nuclear reactions induced by fast
neutrons are under preparation (or were already conducted) at the Department of Nuclear
Reactions at the NPI CAS. A new vacuum chamber with silicon detector composed telescopes
will allow us to perform precise measurements of double-differential cross-sections for
interaction (n, cp) induced by fast neutrons with kinetic energies from 5 to 33 MeV. The
current status of development and preparations for experiments with the new vacuum
chamber will be given.
Moreover already measured experimental total cross-section data for reaction nat O(n,tot) will
be shown and a particular experimental approach to transmission experiments will be
described.
