Soft X-ray Diffractometer RASOR in factory test
Soft X-ray Diffractometer designed and built for the Diamond Light Source in Oxford UK to run diffraction and reflectivity experiments. It has a vertical diffraction plane to benefit from the low divergence of the x-ray beam in this direction. This is essential to optimise the reflectivity signal. It has a small sphere of confusion (<50 micron) useful for both diffraction and reflectivity and can be fitted with a sample cryostat for magnetic studies.
Features
- Supported on a motorised table to allow precise positioning on the x-ray beam.
- Two main rotation circles, theta and two theta, with full range of motion, and a chi rotation of up to ±5 deg.
- Sample position can be translated ±20mm perpendicular to the diffraction plane and ±5mm across the plane.
- Additional phi rotation (infinite) can be mounted at the sample position.
- Polarisation analyser allows analysis of the scattered beam and has a full range of motions.
- Can be supplied with a liquid helium cryostat to allow cooling of samples down to at least 10K
- A number of different sample stages can be used, simple mounts for low temperature, a piezo rotation stage to provide phi rotation and a stage with permanent magnets to provide a magnetic field at the sample position.
