Abstract
Abstract
An intense epithermal neutron flux is necessary for boron
neutron capture therapy (BNCT), a promising technique for the
treatment of malignant tumors. The epithermal neutron flux is an
essential characteristic of the BNCT neutron beam and its
measurement is directly related to the reliability of the treatment
planning system. Such a tool could be a cylindrical activation
detector using 71Ga(n,γ)72Ga reaction. This paper
describes a detector made in the likeness of the previously proposed
one and presents the results of numerical simulation of the detector
sensitivity and its experimental use. The paper notes the difference
between the simulated sensitivity of the detector and the
sensitivity of the previously proposed one and makes assumptions
about the reason for this difference. The work also proposes an
improvement of the detector, which allows not only to reduce the
contribution of fast neutrons to the detector sensitivity, but also
to provide a new opportunity to refine the spectrum of neutrons that
are most effective for the treatment of deep-seated tumors.
