abstract = {The HBS project for a High Current Accelerator-based
Neutron Source (HiCANS) uses a pulsed proton beam of 70 MeV
energy and 100 kW of time-averaged power for each target
station. With the benefit of the time structure, a low
background, and flexible, high brilliance moderator set-ups,
the instruments at the HBS are expected to be very
competitive to existing state-of-the-art scattering
instruments [1]. The low dimensional moderators of the HBS
are well suited for instruments studying small samples. A
prototypical example is neutron macromolecular
diffractometers, where typical sample volumes reach from
0.01 mm3 to 1 mm3. In this work, the design progress of a
macromolecular diffractometer for the HBS will be presented.
SELENE neutron guides will be used in this instrument. The
neutron optics have been optimized with VITESS Monte Carlo
simulations. With the optimized neutron optics, we can
obtain a low background, and a very bright, tunable neutron
beam spot at the sample with a cross-section as small as 1
mm2, thus promising a very competitive instrument for the
life science community.This work is part of the
collaboration within ELENA and LENS on the development of
HiCANS. It has been funded in part by BMBF, GNeuS, and
CSC.[1] Gutberlet T. Conceptual Design Report-Jülich High
