abstract = {The instrumental concept of HERITAGE – a reflectometer
with a horizontal sample geometry – well fitted to the
long pulse structure of a neutron source is presented. It is
constitutes a new class of reflectometers achieving the
unprecedentedly high flux for classical specular
reflectometry combined with off-specular reflectometry and
grazing incidence small-angle scattering (GISANS), thus
resulting in a complete 3-d exploration of lateral and in
depth structures in thin films. This is achieved by
specially designed neutron guides. In the horizontal
direction (perpendicular to the scattering plane) the
guide's elliptic shape focusses the neutrons onto the
sample. In the vertical direction a multichannel geometry
provides a smooth divergence distribution at the sample
position while accepting the entire beam from a compact
high-brilliance flat moderator.The modular collimation setup
of HERITAGE provides extremely high flexibility in respect
to sample geometries and environments, including the
possibility to study virtually all types of solid and liquid
interfaces, statically or kinetically. The use of multiple
beam illumination allows for reflectivity and GISANS
measurements at liquid interfaces both from above and below
without a need to move the sample.This concept assures the
delivery of the maximum possible and usable flux to the
sample in both reflectivity and GISANS measurement regimes.
The presented design outperforms the flux of all present-day
and already for the ESS planned reflectometers and GISANS
setups in flux and in measuring time for standard samples.},
