摘要： An X-ray spectroscope collects an energy-dispersive spectrum from a sample under analysis, and generates a list of candidate elements that may be present in the sample. A wavelength dispersive spectral collector is then tuned to obtain X-ray intensity measurements at the energies/wavelengths of some or all of the candidate elements, thereby verifying whether or not these candidate elements are in fact present in the sample. Additionally, the alignment of the wavelength dispersive spectral collector versus the sample can be optimized by tuning the wavelength dispersive spectral collector to the energy/wavelength of a selected one of the candidate elements—preferably one whose presence in the sample has been verified, or one which has a high likelihood of being present in the sample—and then varying the alignment of the wavelength dispersive spectral collector versus the sample until the wavelength dispersive spectral collector returns the maximum intensity reading for the selected candidate element. Intensity readings for the other candidate elements can then be collected at this optimized alignment.

摘要： In an energy dispersive spectrometer wherein event (particle/photon) detection is performed by counting events spaced by greater than a shaping time, events which are spaced by less than the shaping time are also collected and counted. These “combined events” are treated similarly to “single events” which are spaced by greater than the shaping time, and can be used to generate combined-event spectra for comparison and/or use with the conventional single-event spectra. The combined-event spectra can be compared to the single-event spectra to provide an indication of data quality; can be subtracted from the single-event spectra to remove artifacts, and/or can be deconvolved into a single-event spectrum to increase the resolution of the single-event spectrum.
摘要翻译：在能量色散光谱仪中，其中事件（粒子/光子）检测通过计数大于成形时间的事件进行计数，同时收集和计数间隔小于成形时间的事件。这些“组合事件”的处理类似于间隔大于整形时间的“单个事件”，并且可以用于生成用于与常规单事件光谱进行比较和/或使用的组合事件光谱。组合事件光谱可以与单事件光谱进行比较，以提供数据质量的指示; 可以从单事件光谱中减去去除伪像，和/或可以去卷积成单事件光谱以增加单事件光谱的分辨率。
