Instrument d19 is a neutron 4-circle diffractometer that can be used to carry out high resolution work on relatively small single crystals that have large unit cells, and is routinely used to carry out such work of interest in biological systems, materials science, physics, and chemistry.

The instrument has a multiwire area detector. This also allows high-angle neutron fibre diffraction experiments to be carried out and a significant fraction of beamtime on d19 is awarded for experiments on biological and synthetic polymer systems including nucleic acids, filamentous bacteriophages, cellulose, hyaluronic acid, and industrial polymers.

If you are considering an experiment on d19, please do not hesitate to contact either instrument responsible :

Trevor Forsyth (tforsyth@ill.fr, or phone +33 (0) 4 76 20 71 58)
Sax Mason (mason(at)ill.fr, or phone +33 (0) 4 76 20 70 67)

or for technical questions (sample mounting etc), you can contact the instrument technician for D19 and D :

John Archer (archer(at)ill.fr)

who will be more than happy to discuss the work that you are interested in doing and the best way forward. Other ILL scientists with detailed knowledge of D19 are :

Thomas Hansen (hansen(at)ill.fr)
Garry McIntyre (mcintyre(at)ill.fr)
Emmanuelle Suard (suard(at)ill.fr)

There are a number of different diffractometers at the ILL and if d19 is not the best one for your work, we will point you in the right direction. Check this link for information on the other single crystal diffraction instruments:
 

Diffraction group single crystal diffractometers (D3, D9, D10, D15, D23)
Longer wavelength diffractometers (in the Large Scale Structures group) (D16, DB21, LADI)
