| 摘要 |
An X-ray spectrometer in which, in order to increase the power of the primary X radiation projected onto a sample (1) to be analysed and/or for extending the range of wavelengths of the primary radiation, a number of X-ray tubes (19, 23) are arranged opposite to a sample holder (1a) of an X-ray spectrometer. The invention is applied in sequential X-ray spectrometers and multi-channel X-ray spectrometers. <IMAGE>
