Abstract
An X-ray scattering chamber 12 includes a housing 14 that may be mounted in X-ray diffraction equipment between an X-ray source 2 and an X-ray detector 4, for example on goniometer arm 6. The housing 14 includes sample holder 16 and beam conditioning optics 22,24, but the system also makes use of primary optics 10 outside the housing. The equipment is suitable for SAXS and/or SAXS-WAXS.
Claims12
An X-ray diffractometer, comprising:
- an X-ray source for directing incident x-rays to a sample measurement position;
- an X-ray detector for detecting output x-rays from the sample measurement position;
- a goniometer for adjusting the position of at least one of the source, detector and the sample;
- and
- an detachable x-ray scattering chamber including:
- a gas-tight housing having an x-ray input window for receiving incident x-rays from the x-ray source and an x-ray output window for passing the scattered x-rays to the x-ray detector;
- at least one beam conditioner between the x-ray input window and sample measurement position for conditioning the incident beam and at least a beam stop between the sample measurement position and the x-ray output window;
- and
- mounting means for detachably mounting the chamber in position.
An X-ray scattering chamber, adapted to be mounted in an X-ray diffractometer including an X-ray source, an X-ray detector, and a goniometer for adjusting the position of at least one of the source and detector around the sample measurement position, the X-ray scattering chamber comprising:
- a mount for reproducible placement and removal of the chamber;
- a gas-tight housing having an x-ray input window for receiving x-rays from the x-ray source and an x-ray output window for passing the scattered output x-rays to the x-ray detector;
- and
- at least one beam conditioner between the x-ray input window and sample measurement position for conditioning the incident beam and at least one beam stop between the sample measurement position and the x-ray output window for conditioning the output x-rays.
A method of operation of an X-ray scattering chamber having a mount for reproducible placement and removal of the chamber;
- a gas-tight housing having an x-ray input window for receiving x-rays from the x-ray source and an x-ray output window for passing the scattered output x-rays to the x-ray detector;
- and
- at least one beam conditioner between the x-ray input window and sample measurement position for conditioning the incident beam and at least one beam stop between the sample measurement position and the x-ray output window for conditioning the output x-rays;
- including:
- detachably mounting the X-ray scattering chamber in the X-ray diffraction equipment;
- carrying out measurements on a sample with the x-ray scattering camera attached
- detaching the X-ray scattering chamber from the X-ray diffraction equipment.
