Abstract:

Boron Neutron Capture Therapy (BNCT) is a new type of radiotherapy which has 
been widely concerned by many
researchers. At present, the neutron source for boron neutron capture therapy 
has been gradually transitioning
from reactor neutron source to accelerator neutron source. The development of 
compact neutron sources for
boron neutron capture therapy is the focus of neutron source research. In 
this seminar, I will present the PhD
study on the neutron source facility of Accelerator-based Boron Neutron 
Capture Therapy, including the
development of target, Beam Shaping Assembly (BSA) and related neutron 
measurement work.

The High Brilliance Neutron Source (HBS) project is developing a high-current 
accelerator-driven neutron
source (HiCANS) to maintain a healthy neutron landscape in Europe. Despite 
the lower primary neutron yield of
the nuclear reactions compared to reactor or spallation neutron sources, 
HiCANS achieve a competitive neutron
brightness by a compact moderator and reflector design, which makes a large 
fraction of the primary neutron
spectrum available for applications. The spectral and temporal, i.e. 
frequency and pulse length,
characteristics of the neutron pulse are tailored to the instruments hosted 
at a target station. Based on the
‘pancake’ and ‘butterfly’ moderator geometries developed for the European 
Spallation Source (ESS), we
investigate a pancake-like structure by means of Monte Carlo simulations. In 
this seminar, I will also present
the current study of pancake-like moderator-reflector structures. The 
optimized structure with up to 12
extraction channels in a pancake-like arrangement looks therefore very 
promising for target stations that
serve a large number of thermal and cold instruments.
