The neutron diffraction group is operating three instruments at the Swiss continuous spallation neutron source SINQ: The high resolution neutron powder diffractometer HRPT , covering 160o in 2Θ, the cold neutron powder diffractometer DMC , covering 80o, the neutron single crystal diffractometer TriCSand the crystal testing instrument Orion.
| DMC | cold powder diffractometer | λ=2.3 - 6 Å , Δd/d ≥ .006, 400 channels (0.2o) | |
| HRPT | thermal powder diffractometer | λ=0.94 - 2.41 Å, Δd/d ≥ .0009, 1600 channels (0.1o) | |
| TriCS | thermal single crystal diffractometer | λ=1.18 Å, 2.32 Å , Δd/d ≥ .005, 4-circle open cradle and tilt-mode |
|
| Orion | cold test instrument | λ=2.215 Å , double-goniometer (+/- 12 deg) and closed 4-circle-cradle (fall 2010) |
Beside the research of the diffraction group and the LNS research in condensed matter physics ( click for latest reports ), we support external users of our instruments in performing the experiments and in the first data treatment. Well prepared experiments together with the collaboration between outside and inside experts is very fruitful and yields excellent results. We are well supported by the LDM department concerning computing and sample environment and the condensed matter theory group (CMT) in the evaluation of our data.
A permanently updated publication list is available from the LNS web page.

Instrument Projects
DMC Upgrade: Unmagnetic neutron powder diffraction instrument with extended 2-dimensional-banana detector (Approved by PSI Forschungskommission FOKO in June 2005, financing starts January 2010, to be operational in 2012/3). Layout DMC-2.
Laue Auxilary on POLDI (PLC):
We are presently completing a LAUE usable as an auxilary (like a cryostat) on POLDI. The first tests on this beamline were encouraging, as the POLDI position offers a very very low background. The setup under design will include a small electronic 2D-camera, positionable in 2-theta and in height.
First goal: Alignement and test opportunity for crystals at ambient temperature using neutrons. PLC.
Orion: Test facility for crystals alignment and student training. The station is presently under design. First parts are ordered. Orion Layout.
We are partner in the 2-year Erasmus Mundus Program MaMaSELFNext deadline for applicants with Swiss citizenship: February 2010 (exact date will follow).
Upcoming workshops and schools:
MaMaSELF-III 2010, Rigi Kulm , May 3-6, 2010
The diffraction group has no open position at the moment.
