[en] The D33 small-angle neutron scattering (SANS) instrument at the Institut
Laue–Langevin (ILL) is the most recent SANS instrument to be built at the ILL.
In a project beginning in 2005 and lasting seven years, the concept has been
developed, and the instrument designed, manufactured and installed. D33 was
commissioned with neutrons during the second half of 2012, fully entering the
ILL user programme in 2013. The scientific case required that D33 should
provide a wide dynamic range of measured scattering vector magnitude q,
flexibility with regard to the instrument resolution, and the provision of
polarized neutrons and 3He spin analysis to facilitate and expand studies in
magnetism. In monochromatic mode, a velocity selector and a flexible system of
inter-collimation apertures define the neutron beam. A double-chopper system
enables a time-of-flight (TOF) mode of operation, allowing an enhanced
dynamic q range (qmax/qmin) and a flexible wavelength resolution. Two large
multitube detectors extend the dynamic q range further, giving qmax/qmin ’ 25 in
monochromatic mode and a very large qmax/qmin > 1000 in TOF mode. The
sample zone is large and flexible in configuration, accommodating complex and
bulky sample environments, while the position of D33 is such as to allow high
magnetic fields at the sample position. The instrument is of general purpose with
a performance rivalling that of D22, and is well adapted for SANS studies in
scientific disciplines as diverse as solution scattering in biology and soft matter
and studies of physics, materials science and magnetism. This article provides a
detailed technical description of D33 and its performance and characterization
of the individual components, and serves as a technical reference for users of the
instrument.
