Abstract
An x-ray diffractometer has an x-ray detector and an x-ray source mounted on vehicles traveling along an arc-shaped track around a sample. The vehicles move independently. Alternatively, the vehicles can move independently on separate parallel tracks.
Claims11
An x-ray diffractometer comprising
- a. an x-ray source;
- b. an x-ray detector;
- c. at least one arc-shaped track;
- d. a source vehicle for carrying the x-ray source along the at least one arc-shaped track;
- e. a detector vehicle for carrying the x-ray detector along the at least one arc-shaped track, the detector vehicle moving independently from the source vehicles
- f. a chi tilt mechanism for tilting the arc-shaped track;
- wherein
- the track subtends an angle of greater than 180.degree.;
- and
- the chi-tilt mechanism is arranged to achieve a chi-tilt near or past horizontal.
