      Britain reclaimed the x-ray spectroscopy mantle when David Turner, an Oxford physicist, developed ultraviolet photoelectron spectroscopy, or UPS, using helium as a photon source. His method was later applied to solid surfaces, where it was used to study adsorption and formed some of the foundations of quantum chemistry. X-ray spectroscopy is sample dependent, so requires high quantum efficiency and experimental flexibility. The SOPHIA-XO offers excellent >95% quantum efficiency over the large energy range 5 eV – 30 keV, with high frame rates and multiple port readouts.

The Large Area X-ray Spectroscopy (LAXS) mission concept study continues to evolve strongly following the merging of the LAXS mission with the Next Generation Skip to main content This banner text can have markup. The HTXS mission represents a major advance, providing as much as a factor of increase in sensitivity over currently planned high resolution X-ray spectroscopy missions.

HTXS will mark the start of a new era when high quality X-ray spectra will be obtained for all classes of X-ray sources, over a wide range of luminosity and Size: 9MB. The Large Area X-ray Spectroscopy (LAXS) mission study concept has evolved strongly over the last year culminating in the merging of LAXS with the Goddard Space Flight Center (GSFC) proposal for a similar mission, the Next Generation X-ray Observatory (NGXO, PI: Nick White).

We are studying a Large Area X-ray Spectroscopy Mission conceived and sized to address a range of fundamental astrophysical questions such as: the role of flares and microflares in heating stellar coronae - the impact of metallicity on the Eddington limit in accreting binaries - the enrichment of the interstellar and intracluster medium - the formation of galaxies from cooling cluster gas, and - the Author: Tananbaum, H.

X-Ray Spectroscopy: An Introduction (Springer Series In Optical Sciences) 2nd Edition by Bipin K. Agarwal (Author)5/5(1). X-ray Spectroscopy 1. Introduction X-rays are KeV photons. Atomic X-rays are emitted during electronic transitions to the inner shell states in atoms of modest atomic number.

These X-rays have characteristic energies related to the atomic number, and each element therefore has a characteristic X-ray spectrum. In this experimentFile Size: KB.
