abstract = {Compact accelerator-driven neutron sources allow to operate multiple optimised target-moderator-reflector (TMR) units adapted to the requirements of the respective instruments. The compact design of the TMR units allows an efficient coupling of neutron production, neutron moderation and extraction, but requires a novel way of optimisation. The neutronic performance of different TMR units based on polyethylene, heavy water and a mixture of heavy and light water moderators together with Pb and Be reflectors and a borated polyethylene absorber is discussed. Extraction channels for thermal and cold neutrons are investigated regarding the energy and time spectra.},

abstract = {Organic aromatic cold neutron moderators - like mesitylene (C9H12) - are often much more convenient to handle and to commission than cryogenic methane or ortho/para hydrogen moderators. Although this benefit comes at the cost of reduced brilliance, mesitylene moderators are suited to enable cold neutron applications at sources where a complex traditional cold moderator system is not feasible. Developing the Jülich High Brilliance neutron Source (HBS) project, we have investigated the use of such a low-dimensional mesitylene moderator with MCNP and ANSYS simulations and validated the simulations with experiments at TU Dresden's AKR-2 reactor. Here we will document the feasibility, advantages and drawbacks of such a system and give an outlook on future optimization potentials.},

abstract = {The results of a parametric study are presented which was conducted in the framework of the High Brilliance Neutron Source Project (HBS), in order to optimise the target dimensions for a Compact Accelerator driven Neutron Source (CANS). A thin disc shaped target cooled by a water jet was taken as design reference, which was recently published in the Conceptual Design Report for NOVA ERA (Neutrons Obtained Via Accelerator for Education and Research Activities). For a given target thickness, limited by the ion range in the target material, the cooling fluid pressure and the heat deposition of the ion beam, an optimal diameter of the target disc can be found, for which the occurring stresses are minimised. With the accelerator parameters of NOVA ERA (10 MeV protons with an average power of 400 W on the Target) and with the results of the parametric study, it was possible to design a target, where the occurring stresses are by a factor 3 smaller than the yield strength of the employed beryllium alloy, S-65C VHP.},
