The G. A. Siwabessy research reactor is a light-water open-pool type reactor that uses materials testing reactor (MTR) type fuel element of U3Si2Al MTR with U-235 low enrichment (19.75%). The reactor, whose nominal thermal power is 30 MW, will have a thermal neutron flux as high as 2.5 x 1014 n cm2 sec-1 at the center irradiation position in the core. The 36 meter BATAN SANS spectrometer (SMARTer) is installed at the end of a 49-meter long neutron guide and situated in the neutron guide hall. The neutron beam is monochromatized by a mechanical velocity selector with 11 ? 19 % wavelength resolution, the incident neutron wavelength is 2.74 - 5.66 Å. The 2-dimensional position sensitive detector has a sensitive area of 60 x 60 cm2 that is divided into 128 x 128 detection elements. SMARTer covers the Q -range of 0.002 < Q (Å-1) < 0.6. A detailed instrument description including measured samples is available in the SMARTer web page.

(updated: September 08th, 2009)

In January 2009 HMI and BESSY have merged to form the Helmholtz-Zentrum Berlin für Materialien and Energie (HZB). The HZB operates two large scale research facilities: the reactor BER II on the Lise-Meitner-Campus in Berlin-Wannsee (user office HZB-Neutrons) and the third generation synchrotron source BESSY II on the Wilhelm-Conrad-Röntgen-Campus in Berlin-Adlershof (user office HZB-Photons).

1 March and 1 September

The 10 MW reactor BER II supplies a thermal neutron flux of 1.2 x 10¹⁴cm^-2s^-1; it is equipped with a cold source. Instrument V4-SANS (0.001 < Q/Å^-1 < 0.85) with multidetector of 4K elements of 10 mm x 10 mm cross section and up to 16 m secondary flight path. Double Crystal Diffractometer V12a-USANS (0.00003 < Q/Å^-1 < 0.02) with an asymmetric Si crystal in the (111) Bragg reflection as monochromator and an elastically bent asymmetrically cut Si crystal in the (111) Bragg reflection as analyzer; the scattering diagram is recorded as a whole by a two-dimensional position sensitive detector. Instrument V16-VSANS (0.0001 < Q/Å^-1 < 0.85; under commissioning) is equipped with a detector  made of 112 PSD tubes of 1m height giving pixels of about 10x10 mm2 on 1 m2. A low-q mode runs with multi-pinhole collimation and a 30x33 cm2 area detector (2x3 mm pixels).

The experimental program is dedicated preferentially to fundamental and applied Materials Science, Magnetism and Soft Condensed Matter research. Polarised neutrons are available on V4-SANS1. Up to 70% of the beam time is available for external users.

Applications for access to the HZB facilities (neutrons and photons) should be made by using the General Access Tool GATE which provides web applications to submit proposals, experimental reports, publications etc.

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.

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.
