Improved double crystal X-ray spectrometer |
| abstract |
A dual Channel Spectrometer system is provided for measurement of X-ray spectra in which at least two pairs of crystals (1,2 and 4,5) are arranged in a crystal changer so that different pairs of such crystals can be selected in the X-ray spectrometer. This selection is achieved by rotating a drum (10) on which pairs of crystals are mounted about an axis to bring one pair of crystals into alignment with a collimated X-ray beam. This enables the selection of the wavelength range used in the spectrometer to be made without deactivating the spectrometer or without loosing the vacuum in the spectrometer. |
