Monochromatic Neutron and X-Ray Powder diffractometer
Instrument definition for a powder diffractometer at a monochromatic neutron or X-ray beam. This is both suited for a powder diffractometer with a single detector or a powder diffractometer with a position sensitive detector.
Symbols:
The symbol(s) listed here will be used below to coordinate datasets with the same shape.
i: i is the number of wavelengths
