Claims
- 1. Apparatus for producing an x-ray beam with a width `w`, said apparatus comprising:
- an x-ray source having a spot size width `y`; and
- a multiple-total-external reflection monolithic capillary optic ("optic") having an input and an output and being positioned such that said input to said optic faces said x-ray source and is disposed at an optic-to-source distance of less than 60 millimeters, said optic having multiple channels each of which has an input aimed at said x-ray source, said output of said optic providing said x-ray beam of width `w`.
- 2. The apparatus of claim 1, wherein said spot size width `y` is of less than 300 micrometers.
- 3. The apparatus of claim 2, wherein said x-ray beam comprises a quasi-parallel x-ray beam.
- 4. The apparatus of claim 1, wherein said x-ray beam comprises a quasi-parallel x-ray beam.
- 5. The apparatus of claim 1, wherein said spot size width `y` is sufficiently small to maximize intensity of said x-ray beam with width `w` with said optic disposed at said optic-to-source distance of <60 millimeters.
- 6. The apparatus of claim 1, wherein said x-ray beam comprises a quasi-parallel x-ray beam and said x-ray source has a spot size width `y` of approximately 30 micrometers, and wherein the optic-to-source distance is approximately 1 millimeters such that said optic produces at its output a quasi-parallel x-ray beam with a width `w` of 1 millimeter.
- 7. Apparatus for producing a focused x-ray beam with a spot width `w`, said apparatus comprising:
- an x-ray source having a spot size width `y`; and
- a multiple-total-external reflection monolithic capillary optic ("optic") having an input and an output, and being positioned such that said input to said optic faces said x-ray source and is disposed at an optic-to-source distance of less than 60 millimeters, said optic having multiple channels each of which has an input aimed at the x-ray source and an output aimed at an output focal point spaced from the output of said optic, said output of said optic providing said focused x-ray beam.
- 8. The apparatus of claim 7, wherein said spot size width `y` is of 100 micrometers, the optic-to-source distance is approximately 27 millimeters, and said optic has an output focal length of approximately 2 millimeters.
- 9. The apparatus of claim 8, wherein said optic input has a diameter of 7 millimeters and the input of each channel of said multiple channels in said optic is 14 micrometers.
- 10. The apparatus of claim 7, wherein said spot size width `y` of <300 micrometers.
- 11. The apparatus of claim 7, wherein said spot size width `y` is sufficiently small to maximize intensity of said focused x-ray beam with spot width `w` with said optic disposed at said optic-to-source distance of <60 millimeters.
