Target-Moderator Unit

A higher power target is under development for operation at a high-power high brilliance accelerator-based neutron source following the design parameters of the HBS. The target is made of tantalum with an innovative micro-channel cooling system. The target will have a compact design with dimensions of 10 x 10 cm2 to withstand a potential power of 1 kW/cm2. Stability and performing tests will be done and the concept will be continuously improved.

The target will be surrounded by a compact moderator and shielding structure. It will allow the extraction and provision of produced neutrons by separate extraction channels placed around the target. A prototype of this structure is currently under construction at the Central Institute of Engineering and Technology (ZEA-1) of Forschungszentrum Jülich.
