Science Motivation: Nomenclature of X-ray spectroscopy (Recommendations 1991) 737 The nomenclature used for X-ray emission spectra was introduced by M. Siegbahn in the 192@'s and is based upon the relative intensity of lines from different series. It gives no infor- mation about the origin of these lines. Since it was introduced, a number of lines have been As you're sitting in the dentist's chair, you might be told you need a dental X-ray.

X ray spectroscopy

The objective of the mission is to investigate celestial X-ray objects in the Universe with high-throughput imaging and high-resolution spectroscopy. XRISM is expected to launch in the Japanese fiscal year 2022 (TBR) on a JAXA H-IIA rocket. X-Ray Fluorescence Spectroscopy (XRF) – Basics The energy dispersive X-ray fluorescence spectroscopy (XRF) is a method for measuring the thickness of coatings and for analysing materials. It can be used for the qualitative and quantitative determination of the elemental composition of a material sample as well as for measuring coatings and coating systems. The X-rays (5–20 Å) are rich in spectral lines emitted by hot plasma, from 3 to 15 MK, although most hot lines are blended, hence extremely high resolution spectroscopy is needed.

These techniques provide exceptional spatial resolution (down to few tens of a nanometre), but can also be used to analyse and produce images of large areas, up to the size of several square metres. A particular focus of these setup is the spectroscopy in the "tender" x-ray range from 1keV to 5keV including the science of sulfur and phosphor based polymers. A good overview can be found in this paper: Uhlig, Table-Top Ultrafast X-Ray Microcalorimeter Spectrometry for Molecular Structure.

The advantages of x-ray fluorescence spectrometers are that there is no need for sample prep (the material can simply be placed in the beam), and that it is a non-destructive analysis technique.
