Figure 1
A schematic diagram of the SXD instrument. The neutrons leave the target and are energy-shifted by the water moderator. The size of the beam impinging on the sample position is defined by the adjustable BN jaws. The sample position is surrounded by 11 detectors, six in the equatorial plane and five below, maximizing the volume of reciprocal space that can be measured with one sample orientation. The frame that supports the detectors is shown in more detail in Fig. 2. Using the ISIS in-house software (SXD2001), the centre of each detector is defined by angles from the incident beam direction, denoted γ in the horizontal plane and νM in the vertical plane. |
