      abstract     = {High-Current Accelerator-driven Neutron Sources (HiCANS)
                      are a promising new type of neutron source with the
                      potential to serve as national neutron sources, providing an
                      alternative to research reactors. Several countries are
                      currently developing HiCANS facilities, including Germany's
                      High Brilliance neutron Source (HBS), which has been
                      described in a Technical Design Report.As part of the
                      preparation for its construction, a prototype of the HBS is
                      planned to be built on the campus of the Forschungszentrum
                      Jülich (FZJ) in Jülich, Germany, within the next decade.
                      The prototype will be equipped with five instruments: a SANS
                      instrument, a reflectometer, an imaging instrument, a PGNAA
                      instrument, and a diffractometer. The diffractometer is
                      being designed in collaboration with RWTH Aachen University
                      and will function as a flexible time-of-flight instrument
                      suitable for various neutron diffraction applications.The
                      applications of the diffractometer will include powder
                      diffraction, single crystal diffraction, and engineering
                      diffraction. Its design will be developed through an
                      iterative simulation process to optimize the final layout
                      for all the above setups. This versatility is facilitated by
                      different source frequencies and duty cycles, variable
                      collimation, and movable detector elements. High resolution
                      will be achieved through pulse shaping using a dedicated
                      chopper system. With a compact length of only 25 meters, it
                      will offer a large bandwidth. Furthermore, technical
                      implementation of the developments is coming into focus as
                      well.The simulation and iterative optimization of a
                      flexible, multi-purpose diffractometer will allow to tailor
                      dedicated diffraction instruments utilizing the particular
                      strengths of the HBS source and potential future extensions.
                      The high degree of flexibility also considers the needs of
                      different user groups and science cases. Now is the time to
                      initiate these developments. For this, the involved groups
                      are building on the experience gained from previous
                      cooperation projects.},
