In many ways our most important beam instrument at OPAL will be the QUOKKA small-angle scattering instrument.  It is the largest (40-m long after the guide bunker) and most expensive ($4.5M + IT and Electrical Engineering), and was a major driver for getting the high-performance cold source into OPAL. It will have the highest throughput of users, and will cover the broadest range of scientific areas. 

Small-angle scattering is a powerful technique for looking at sizes and structures of objects on the nanoscale (1-10nm), like polymer molecules, biological molecules, defect structures in metals and ceramics, pores in rocks, magnetic clusters, magnetic flux lines in type-II superconductors and so on.  ANSTO will have both X-ray and neutron small-angle scattering adjacent to each other, and the advantage of neutrons is primarily for soft matter where the contrast-variation method (replacing hydrogen with deuterium) can be used.  In addition, it is useful for magnetic problems and ones in which large samples must be used.  In many ways, small-angle scattering is complementary to electron microscopy while direct imaging is the domain of electron microscopy, SAXS and SANS can provide particle sizes, shapes and distributions averaged over a complete macroscopic sample.  Small-angle scattering is rarely able to solve a problem on its own, and is typically used in conjunction with a number of other techniques. 

SANS was crucial in showing that polymer molecules are self-avoiding random walks (Flory's prediction - Nobel Prize in Chemistry, 1974), and that Type-II superconductors allow magnetic flux to penetrate, forming a lattice of magnetic vortices (Abrikosov's prediction - Nobel Prize in Physics, 2003).  Other major achievements have been understanding viscosity modifiers in lubricants, solving the coarse structure of the ribosome, understanding the nature and role of particulate additives to tyres, and the porosity of sedimentary rocks in oil and gas reservoirs.

Our goal is to have an instrument very similar in the spirit to the 40-metre D22 instrument at Institut Laue Langevin in Grenoble, France and the 30-metre instruments on NG3 and NG7 at the National Institute for Standards and Technology in Gaithersburg in the USA.

    REFSANS:

     

    REFSANS is an horizontal reflectometer operating in time of flight (TOF) mode.

    It has been optimized for soft matter samples and liquids but is very often used for other types of systems as well.

    The instrument can be used in two distinct modes, namely

    1) conventional reflectometry (specular and off specular) with a beam of up to 170X12 mm2  provided by a collimation composed of lateral super mirrors delivering a large horizontal divergence and a reduced vertical divergence.

    2) Grazing Incidence Small Angle Neutron Scattering (GISANS) which enables the resolution of latteral structures in thin films and interfaces in a range between nanometer and microns. The super mirrors are moved out of the beam in this configuration and The beam size and divergence are further reduced by pinholes in order to remove the horizontal smearing used in conventional reflectometry.

    In case of large (up to 80mm wide) samples, GISANS can be performed using a multi beam option where a radial collimator is used to illuminate the full sample surface and get a single focus point on distant detector (9 meters from the sample, ensuring a high angular resolution and a low background) 

     

    The chopper system resolution can be tuned between ca. 1% and 10 to 20%.

    The detector is a 500X500mm2 3He multiwire detector with very low gamma sensitivity. It can be positioned in vacuum at any distance between 1.5 and 12m from the sample and its height can be adjusted in order to cover up to 6 degrees scattering angle at the largest distance.

    The sample position is normally equipped with a Huber goniometer (200 kg maximum load) but this can be replaced by any user setup. Large systems such as sputtering chambers and large magnets can be accommodated.

    Beam polarisation can be provided for beams up to 30 mm in width (an upgrade to a full 170 mm beam width is in progress with commissioning planned for 2013)

    An upgraded SANS instrument has recently been commissioned at the 2 MW IFE reactor. The instrument is installed on an LH2-filled cold moderator, and is equipped with a velocity selector (Dornier), providing wavelengths in the range of 4.5 to approx. 10 Å. Fast neutrons (below 4 Å) and gamma radiation is removed by means of Be- and Bi- filters. The detector is a circular (58 cm diameter) 3He-filled Risø-type detector that is translated inside a 3.5 m long shielded tank. The sample is mounted on a rotatable 7-position thermally controlled stage located inside a steel chamber. The chamber can be evacuated in order to reduce air scattering, and also for working with air sensitive samples. The Q-range for this instrument is 0.008-0.32 Å-1. Beamtime is allocated on a collaborative basis. Annual reactor shut-downs are from first week of July through the first week of August, Christmas, New Year and Easter.

    Pulsed neutron source operated for five months starting July 2001; eight months operation is planned in 2002 starting in May. Instrument LQD was upgraded to a second generation TOF SANS instrument, including a zero time chopper, a frame definition chopper and a new collimation and gravity focussing system. A new partially decoupled cold moderator and an upgrade of the source to support a proton current of 100 µA make gives LQD the brightest cold pulsed available. A new high data rate detector will be installed for 2002. General information and proposal forms: http://lansce.lanl.gov/userprogram/index.shtml.

    Deadlines for the submission of proposals: calls for proposals issued twice per year; deadlines are posted at the above URL

    NIST's research reactor operates at 20 MW, with a liquid hydrogen cold source. Two 30 m SANS instruments are in operation; one with a polarized beam option. The instruments have velocity selectors with wavelength resolution from 10 % to 30 % and multidetectors of 65 cm x 65 cm sensitive area and 0.5 cm x 0.5 cm pixel size. With conventional pinhole collimation, the Q-range of each instrument is 0.0015 Å-1 to 0.6 Å-1. The instruments are equipped with sets of biconcave lenses near the sample position to focus the beam, thereby improving the low-Q limit to about 0.0008 Å-1. Up to 50 % of the beam time on the instruments is available for visiting researchers who submit proposals. Main research interests are: mesoporous materials (CG and DH); polymers (BH and DH); biology (SK); metallurgy and ceramics (JB); colloids and microemulsions (SRK and LP). In the case of substantially equal proposals, preference will be given to US researchers. The NG3 SANS instrument is partially supported by the US National Science Foundation through its Center for High Resolution Neutron Scattering (CHRNS) that is part of the NIST Center for Neutron Research. General information and proposal forms are available on the Web at the above URL.

    Deadlines for the submission of proposals: 3 copies should be submitted, at any time, to the User Facilities Coordinator (address see below)

    The 85 MW High Flux Isotope Reactor (HFIR) supplies a thermal neutron flux of 1.5 x 1015 cm-2s-1. About 30 % to 50 % of beam time is allocated for user experiments. Over the period 2000-2005, a number of projects habe been undertaken at HFIR to improve neutron scattering capabilities. These include the installation of larger beam tubes and shutters, a high-performance hydrogen cold source, new beam lines and neutron scattering instrumentation, including two completely new SANS instruments: CG-2 and Bio-SANS. The upgrades commenced during an extended reactor outage which began in 2000, for the regularly scheduled replacement of the beryllium reflector. Proposal forms, guest assignement request forms and general information on the upgrades may be obtained by contacting the User Facility Coordinator, Solid State Division, Oak Ridge National Laboratory, P.O. Box 2008, Bldg. 3025, ORNL, Oak Ridge, TN 37831-6033, Phone: +1 865 576 1865, Fax: +1 865 574 4143, Email: carterjk(at)ornl.gov, or by contacting the Internet server.

    Details of the SINQ - call for proposals are available on the web page

    The concept of the spallation neutron source SINQ is that of a steady state neutron source. The SANS instrument (0.0006 < Q-1 < 1) is installed at the end of a 50 mm x 50 mm neutron guide facing a liquid-D2 cold moderator. The neutron wavelength is selected by a mechanical velocity selector at the entrance of an 18 m variable collimator; a detailed instrument description including measured values of neutron flux are communicated in the new WWW-page. The 2-dimensional multidetector has a sensitive area of 96 cm x 96 cm with 16 K elements of 7.5 mm x 7.5 mm cross section and up to 20 m secondary flight path. You can submit the proposals either as an Email attachment sinq(at)psi.ch or by standard means to Stefan Janssen, SINQ Scientific Coordination Office, Bldg.
