Abstract
A sample holder 2 for holding a capillary 40 for X-ray analysis has a first thermal transport member 36 on the base portion 14 on one side of a longitudinal slit 12 and a second thermal transport member 38 on the base portion 16 on the other side. The thermal transport members 36, 38 are compressed between a frame 30 and the base portion 14, 16 in the transverse direction to urge the edges of the first and second thermal transport members together, to hold a capillary 40 longitudinally aligned with the longitudinal slit 12.
Claims18
A sample holder for holding a hollow tube for X-ray analysis apparatus, comprising:
- a base portion having an opening for an X-ray beam;
- a first thermal transport member on the base portion on one lateral side of the opening and a second thermal transport member on the other lateral side of the opening;
- wherein the first and second thermal transport members are deformable to compress the hollow tube laterally to hold the hollow tube such that:
- (i) an X-ray beam can pass through the hollow tube without intersecting any part of the sample holder, and
- (ii) there is thermal contact between the hollow tube and the thermal transport member along the length of the hollow tube and around at least part of the circumference of the hollow tube to conduct heat between the hollow tube and the base portion through the thermal transport member.
An X-ray apparatus for small angle X-ray scattering comprising:
- a hollow tube for X-ray analysis apparatus;
- an X-ray source for supplying an X-ray beam through the opening to a sample mounted in the hollow tube;
- and
- an X-ray detector arranged to detect X-rays scattered a sample in the hollow tube;
- and
- a sample holder comprising:
- a base portion having an opening for an X-ray beam;
- a first thermal transport member on the base portion on one lateral side of the opening and a second thermal transport member on the other lateral side of the opening;
- wherein the first and second thermal transport members are deformable to compress the hollow tube laterally to hold the hollow tube such that:
- (i) an X-ray beam can pass through the hollow tube without intersecting any part of the sample holder, and
- (ii) there is thermal contact between the hollow tube and the thermal transport member along the length of the hollow tube and around at least part of the circumference of the hollow tube to conduct heat between the hollow tube and the base portion through the thermal transport member.
