A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Underneath the surface:Advanced synchrotron techniques for the study of 17th century oil paint in three dimensions [PDF]

In this PhD thesis the composition, morphology and degradation of 17th century paints was studied using state of the art synchrotron radiation (SR) based X-ray methods. The degradation of arsenic sulfide pigments was revealed by studying model systems of

Multielemental Analysis in Rice Grains by Total Reflection X‐Ray Fluorescence

X-Ray Spectrometry, EarlyView.
ABSTRACT Rice (Oryza sativa) is a staple food cultivated worldwide and represents a significant source of essential nutrients for humans. However, this cereal may also contain potentially toxic elements including chromium, arsenic, and lead typically present at trace concentrations (ng.g−1).

Simultaneous measurements of HERFD‐XANES, RXES and RIXS of caesium using a transition‐edge sensor

Journal of Synchrotron Radiation, EarlyView.
A transition‐edge sensor (TES) enables simultaneous measurements of HERFD‐XANES, RXES and RIXS with a high‐energy resolution. This study employed a TES to investigate caesium compounds at the Cs LII‐edge (5359 eV).A transition‐edge sensor (TES) enables high‐resolution measurements of X‐ray fluorescence across a wide energy range, allowing for the ...
