Neutron Diffraction Group
The neutron diffraction group operates four instruments at the Swiss continuous spallation neutron source SINQ: The high resolution neutron powder diffractometer HRPT, covering 160° in 2Θ, the cold neutron powder diffractometer DMC, covering 80°, the neutron single crystal diffractometer ZEBRA, the pulse overlap time-of-flight diffractometer POLDI and the crystal testing instrument Orion.
|DMC||cold neutron powder diffractometer||λ=2.45 - 6 Å , Δd/d ≥ .006, linear detector with 400 channels (0.2°)|
|HRPT||thermal powder diffractometer||λ=1.044 - 2.953 Å, Δd/d ≥ .0009, linear detector with 1600 channels (0.1°)|
|ZEBRA||thermal single crystal diffractometer||λ=1.177 Å, 2.317 Å , Δd/d ≥ .005, 4-circle open cradle and tilt-mode, single and 2D detector|
|Orion||cold neutron test instrument||λ=2.214 Å , closed 4-circle-cradle|

Instrument ProjectsZEBRA: The new single crystal neutron diffractometer optimized for parametric studies and an extended q-range for crystallographic investigations, is under construction at SINQ and its commissioning is expected for 2016 (2D/1D similar to present TriCS) and for the new analyzer unit in 2017.. Design and Characteristics.
DMC: New two-dimensional curved detector, new nonmagnetic sample table
ESS Instrument HEIMDAL: The hybrid instrument HEIMDAL (named after a god in the Norse mythology) is combining thermal and cold neutron diffraction, SANS and neutron imaging in one instrument as requested by many in-situ experiments where samples change for example with time. Chemical reactions, technical materials in operations, materials showing phase separations, where single shot measurements on different instrument would yield information on a different status of the material, will be investigated on different length scales from 0.01nm up to 1000nm.
