Experimental Platform

Based on the JULIC cyclotron at IKP, Forschungszentrum Jülich, an experimental platform for experiments using pulsed high energy proton or deuteron beams for the HBS development has been established in the Big Karl experimental area. The platform makes it possible for proof of principle tests on target and moderator materials, and the validation of neutronic simulations and cold moderator development. Experiments in time-of-flight mode to measure neutron spectra and intensities can also be performed.

Based on the HBS project’s existing experimental station at the Big Karl area, a prototype of the HBS target-moderator-reactor (TMR) assembly will be installed. This will allow further development of HBS’s compact neutron source concept with regard to targetry, neutron provision, moderator development and optimization of the TMR unit to take place. It will also make possible an improvement of neutron provision using tests and new developments in target handling, target cooling systems, biological shielding, and other developments. In addition, proton beam transport devices, beam control and dynamics, beam multiplexing or beam dump systems will be installed and tested at the platform.
The platform will also allow the design, construction and operation of versatile neutron instruments for neutron scattering purposes as well as neutron analytics based on a competitive neutron flux. Taking into account possible upgrades of the beam current of the JULIC cyclotron to a maximum of 10 µA, a beam power of up to 30 W will be achievable.
