TL;DR: The GUPIXWIN program as discussed by the authors has been extended with a Monte Carlo code to provide detector efficiency values that are more accurate than those of the previous approximate analytical formula, and a new batch mode facility is designed to handle two-detector PIXE, with one detector measuring major elements and the other simultaneously measuring trace elements.

TL;DR: Higher abundances of chlorinated hydrocarbons in the mudstone compared with Rocknest windblown materials previously analyzed by Curiosity suggest that indigenous martian or meteoritic organic carbon sources may be preserved in the Mudstone; however, the carbon source for the chlorinatedHydrocarbons is not definitively of martian origin.

TL;DR: The alpha-particle X-ray spectrometer (APXS) for the Mars Science Laboratory (MSL) mission was calibrated for routine analysis of: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Zn, Br, Rb, Sr, and Y as mentioned in this paper.

TL;DR: The Alpha Particle X-ray Spectrometer (APXS) on the Mars Science Laboratory Curiosity rover analyzed air fall dust on the science observation tray (o-tray) in Gale Crater to determine dust oxide compositions.

TL;DR: In this article, APXS data for the active Bagnold dune field within the Gale impact crater (MSL) was used to derive an APXs-based average basaltic soil composition for Mars based on past and recent data from the MSL and MER missions.
