摘要:
An x-ray system or method for exciting a sample under x-ray analysis, using a curved monochromating optic for directing a monochromatic x-ray beam from an x-ray source towards a first focal area. A second optic is positioned within, and receives, the monochromatic x-ray beam, and directs a focused x-ray beam towards a second focal area on the sample. A detector is positioned near the sample to collect radiation from the sample as a result of the focused x-ray beam. The curved monochromating optic produces a beam spot size at the first focal area larger than a beam spot size produced by the second optic at the second focal area, therefore, a beam spot size on the sample is thereby reduced using the second optic. Doubly-curved monochromating optics, and polycapillary optics, are disclosed as possible implementations of the optics.
摘要:
A photo-chemical remediation of Cu-CMP waste streams basically includes the following acts: adding photo-catalyst particles into waste streams containing copper ions and organic pollutants and exposing the waste streams to UV light or sunlight to make copper ions become deposited on surfaces of the photo-catalyst particles. Whereby, the copper ions are removed from the waste streams. Meanwhile, organic and inorganic pollutants are decomposed by the photolysis capability of the photo-catalyst to make the waste streams dischargable within environmental standards to the environment.

摘要:
A monocapillary has a first region of constant inner dimension where the angle of reflection remains essentially constant as radiation is guided therethrough. The monocapillary also has a second region of decreasing inner dimension in a direction toward the outlet where the radiation is guided therethrough. In another embodiment, the monocapillary also has a third region at the inlet of increasing inner dimension toward the outlet direction where the radiation is guided therethrough.
