VIVALDI allows large volumes of reciprocal space to be surveyed rapidly using an image-plate photographic Laue technique with a white neutron beam. The ten fold to hundred fold gain in efficiency over a conventional monochromatic diffractometer allows detailed atomic structural information to be obtained from crystals previously considered to be too small for neutron diffraction.
Complementary too the ILL diffractometers, VIVALDI provides a unique tool for development of new diffraction experiments.

• Rapid structural studies
• Reciprocal-space surveys; identification of twinning and incommensurability
• Very small samples, particularly attractive for high-pressure experiments
• Complete nuclear and magnetic structure determinations through phase transitions
