The Fine Resolution Powder Diffractometer E9 (FIREPOD) is an angle-dispersive powder diffractometer optimized for a flat resolution function with a minimum width of the reflections at the 2Θ-region with the highest density of reflections. The monochromator is placed at a distance of 11 m from the reactor core, which allows for a large take-off angle at the monochromator. An evacuated beam tube and a sapphire single crystal filter reduce air scattering and epithermal neutrons. Neutron...
The reflectometer V6 allows measuring the neutron optical reflectivities on flat surfaces at grazing angles. The reflectivity is related to the variation of the refractive index within a depth of about 200 nm, thus structural depth profiles can be studied at solid-air, solid-liquid and free liquid surfaces.
BioRef is a time-of-flight reflectometer which is intended to focus on soft matter applications, especially at solid–liquid interfaces, for the investigation of biological model systems under physiological conditions including kinetic studies. The instrument was built in a joint collaboration between HZB and the University of Heidelberg with financial support by the BMBF Verbundforschung. Unique features of BioRef are the chopper system, which allows for focusing on a certain Q-range in order to support fast kinetic...

The familiarity of water ice means we often overlook its non-trivial character illustrated, for example, by the many snowflake morphologies resulting from disordered combinations of covalent and hydrogen bonds between hydrogen and oxygen atoms in water ice’s most common phase (Ih) that keep the H_2 O molecular character. Using neutron diffraction on the flat-cone diffractometer E2 at BER-II, Helmholtz-Zentrum Berlin, we probe the atomic scale configuration in the Ih phase of water ice to test...
The instrument name is derived from the flexibility of the spectrometer parameters which permit non-standard experiments and its use in the development of novel methods. The instrument was upgraded in 2011 and rechristened FLEXX. Its new position at the end of the NL1B guide allows a large coverage in wavevector transfer. The guide itself has been upgraded with m=3 neutron supermirrors to allow more neutrons to be transported from the source to the instrument. In...
High Magnetic Field Facility for Neutron Scattering consists of two main components: the High Field Magnet (HFM) and the Extreme Environment Diffractometer (EXED). The former is a dedicated 26 T hybrid magnet, built by the HZB in collaboration with the National High Magnetic Field Laboratory (Florida, US). The latter is a time-of-flight instrument optimized for neutron scattering in restricted angular geometry of the magnet.
The diffractometer is designed for strain and stress analysis for simple geometric samples as well as for industrial applications and heavy components of arbitrary shape. The diffractometer itself consists of two big omega circles (Ω and 2Θ) with a diameter of 800 mm and upon a translation table (xyz-direction) for sample positioning in vertical and horizontal direction. This set up is installed for handling heavy and/or large samples and components such as impellers or turbines...
E6 uses a horizontally and vertically bent monochromator  and an in-pile fan collimator [2, 3]. The fan collimator imitats a vertical slit with adjustable distance to the monochromator. This diffraction geometry achieves a focusing in reciprocal space. At medium resolution, the neutron flux is increased by a factor of two compared with diffractometers that use standard Soller collimators.
The neutron time-of-flight spectrometer NEAT has a long history of successful applications in the study of dynamics and function of materials. It is best suited to probe dynamic phenomena directly in space and time in the large time domain 10-14 – 10-10 s and on the length scale ranging from 0.05 to up to about 5 nm. To address user community needs for more powerful instrumental capabilities, a concept of full upgrade of NEAT has...
