Experimental validation of XRF inversion code for Chandrayaan-1
P. S. Athiray, M. Sudhakar, M. K. Tiwari +5
We have developed an algorithm (x2abundance) to derive the lunar surface chemistry from X-ray fluorescence (XRF) data for the Chandrayaan-1 X-ray Spectrometer (C1XS) experiment. Th…
Mapping lunar surface chemistry: new prospects with the Chandrayaan-2 Large Area Soft x-ray Spectrometer (CLASS)
S. Narendranath, P. S. Athiray, P. Sreekumar +4
Surface chemistry of airless bodies in the solar system can be derived from remote x-ray spectral measurements from an orbiting spacecraft. X- rays from planetary surfaces are exci…
Conceptual challenges and computational progress in X-ray simulation
Maria Grazia Pia, Mauro Augelli, Marcia Begalli +7
Recent developments and validation tests related to the simulation of X-ray fluorescence and PIXE with Geant4 are reviewed. They concern new models for PIXE, which has enabled the…
New techniques in Monte Carlo simulation: experience with a prototype of generic programming application to Geant4 physics processes
Maria Grazia Pia, Mauro Augelli, Marcia Begalli +5
An investigation is in progress to evaluate extensively and quantitatively the possible benefits and drawbacks of new programming paradigms in a Monte Carlo simulation environment,…
Data libraries as a collaborative tool across Monte Carlo codes
Mauro Augelli, Marcia Begalli, Mincheol Han +10
The role of data libraries in Monte Carlo simulation is discussed. A number of data libraries currently in preparation are reviewed; their data are critically examined with respect…
New models for PIXE simulation with Geant4
M. G. Pia, G. Weidenspointner, M. Augelli +4
Particle induced X-ray emission (PIXE) is a physical effect that is not yet adequately modelled in Geant4. The current status as in Geant4 9.2 release is reviewed and new developme…
