Arrangement for the total reflection of X-radiation

摘要

The method for the total reflection of X-radiation is used inter alia for the monochromatisation of long-wave radiation in X-ray spectrometers with parallel beam path. By inserting an arrangement with a plurality of single mirrors arranged in plane-parallel manner at specific distances above one another, the loss of brightness caused by the very small limiting angle (angle of incidence) is compensated. Arrangements of this type can be compared with collimators which exert additional monochromatising effect and influence the spectrum qualitatively.
