D10 - Four-circle diffractometer with three-axis energy analysis
This layout regroups several of the options of D10 (eulerian cradle, analyser, flat-cone detector) while they are not used all at the same time. The advanced He-3 cryostat is not shown except for the air cushion platform for its liquid He-4 Dewar.
D10+ is unique in being the only four-circle diffractometer with optional energy analysis as on three-axis spectrometers. It also possesses a unique four circle dilution cryostat for temperatures down to 0.1K, and offers high reciprocal-space resolution and low intrinsic background, to medium real-space resolution.
D10+ is a fully renewed and upgraded single crystal diffractometer delivering gains of approximately one order of magnitude compared to D10 due to the rebuilt and modernised H24 guide, dedicated end-of-guide position, optimised monochromators and new detector.
The upgrade includes the primary as well the secondary spectrometers with new bidimensional detector. It will be equipped also with a new analyser axis with continuous change of the incident wavelength.
