ERWIN
Powder diffractometer using thermal neutrons
ERWIN (Energy Research With Neutrons) is a high efficiency diffractometer especially dedicated for rapid data collection and parametric material analyses. The two-dimensional position-sensitive 3He wire chamber detector covers a scattering angle range of 135° (in 2θ) as well as a vertical angle range of 15° and thus enables the characterization of powder samples, textured bulk samples and single crystals.
The detector concept enables the recording of diffraction patterns without the need to reposition the detector bench, leading to short measurement times. Thus, ERWIN is well suited for a variety of applications ranging from investigations of solid-state reactions, time-resolved measurements, parametric studies and investigations on small samples.
ERWIN utilizes the monochromator angle of 90° at beam position 8b with a vertically focussing Ge511 monochromator, corresponding to a wavelength of 1.54 Å.
At the next upgrade level, ERWIN will be equipped with three different monochromator positions having discrete 42°, 90° and 120° take-off angles with an optimized primary neutron optics, to enable the flexibility in usage of maximum flux or optimized resolution.
