Paper Abstract

Mars-XRD is an X-ray diffractometer developed for in situ mineralogical analysis of the Martian soil. Mars-XRD main components are 55Fe radioactive source, collimator and CCD-based detector. For spectroscopic requirements the beam section should be smaller than 1x10 mm2 at sample distance. To improve X - ray flux and tuning capability a collimator with converging blades (Soller slits) has been implemented. A dedicated C++ program (XRC-PhOBOS,1 Photon Output and Blade Optimization Software) investigates for the best Soller slits configuration comparing billion of combinations. The out-coming optimized collimator transmits a flux twice higher than a system with blades with the constant angular aperture and five times higher than a two apertures collimator. Software algorithm, updates and examples are illustrated in present paper.
