摘要： An open flow cryostat for cooling a sample in use comprises a supply (1) for supplying a coolant, an outlet (2) for directing a flow of the coolant towards the sample, a supply line (3) for transporting coolant from the supply to the outlet and an isolation line (5) arranged to transport at least some of the coolant away from the outlet. The isolation line (5) is positioned in contact with at least a portion of the supply line (3) to thermally isolate the supply line (3) from the surroundings.

摘要： The present invention provides a high flux X-ray source 100 comprising a sealed X-ray tube contained within an X-ray shield (101), an optic housing 103 containing a multi-layer optic for collecting and focussing X-rays generated in the sealed X-ray tube, and an X-ray beam conditioner 104. The multi-layer optic 103 is located at a predetermined distance from the sealed X-ray tube 101, with the optic housing 103 being adjustable relative to the sealed X-ray tube 101 and the beam conditioner 104 adjustable relative to the optic housing 103. The use of a multi-layer optic provides for the efficient collection and focussing of X-rays generated in a compact sealed tube and wavelength selectively enables it to act as a monochromator, providing a beam of X-rays with a predetermined range of photon energy.

摘要： In the present invention, a frame for mounting a fibre optic taper and a CCD chip in optical contact comprises a resilient support for supporting the fibre optic taper adjacent the CCD chip, means for lowering the fibre optic taper towards the CCD chip and means for applying pressure to urge the fibre optic taper onto the CCD chip. The weight of the fibre optic taper is supported by the resilient support as it is lowered into contact with the chip. Once in engagement with the CCD chip, the fibre optic taper can be pressed against the CCD chip to provide a positive pressure in excess of that due to its weight. As the support is resilient, it provides resistance to the positive pressure, thereby preventing the pressure on the CCD chip from becoming great enough to cause damage to the fragile CCD chip.

摘要： An x-ray diffraction apparatus comprises an x-ray source for generating an x-ray beam, a monochromator for generating a monochromatic x-ray beam from the x-ray beam, and a collimator for collimating the monochromatic x-ray beam and directing it onto a sample, wherein the x-ray source and the monochromator are pre-assembled and fixed with respect to each other in an integrated unit such that in use the path length of the x-ray beam from the source to the monochromator is maintained substantially constant. X-ray flux at the sample is further enhanced by use of a partial monocapillary collimator arranged to direct part of the X-ray beam to the sample by a single grazing reflection.
