Accelerator-driven neutron sources offer a cost-effective
alternative to traditional sources such as fission reactors and
spallation sources. The advent of high-current proton accelerator
systems has given rise to a new class of neutron facility, termed
High-Current Accelerator-driven Neutron Sources (HiCANS), which has
unique properties and capabilities.<br>
<br>
The High-Brilliance Neutron Source (HBS, see <a
class="moz-txt-link-freetext" href="https://hbs.fz-juelich.de/en">https://hbs.fz-juelich.de/en</a>)
project at Forschungszentrum Jülich is developing a HiCANS facility.
It uses a linear accelerator with a pulsed proton beam and a peak
current of up to 100 mA to provide customised proton pulses at
variable frequencies to optimised target stations. These target
stations are more compact than spallation neutron sources because
low-energy nuclear reactions release neutrons from a high-power
tantalum target. This allows for efficient neutron production,
moderation and extraction, enabling competitive neutron instrument
performance.<br>
<br>
A detailed Technical Design Report (TDR) has been published
describing all the relevant components, from the accelerator and
target to the moderators and instruments. It demonstrates the
potential of a national neutron source facility with up to 24
instruments for a variety of applications. A target station
prototype was built at a 45 MeV cyclotron and brought into operation
producing first neutrons in December 2022. Experiments demonstrated
the accessibility and flexibility of this new type of source and
allowed the expected performance to be evaluated. The first stage,
HBS-I, is planned to have a proton energy of 20 MeV, a neutron yield
of 10¹⁵ n/s, and five instruments at a single target station: SANS,
a reflectometer, a diffractometer, an imaging instrument and a PGNAA
instrument.<br>
<br>
Paul Zakalek will present the current status of the High-Brilliance
Neutron Source (HBS) HiCANS project, as well as the next steps and
milestones for this next-generation neutron source.<br>
