Abstract
This project consists in developing a Vibrating Powder Handling System for planetary X-Ray Diffraction instruments. The principle of this novel sample handling technique relies on vibrations generated in a sample holder to create movements in the powdered sample. The major benefit over conventional sample handling techniques is the possibility to characterize materials with grain-sizes up to two orders of magnitude larger, with no degradation in the data quality. It allows existing planetary sample-preparation systems such as rock crushers and drills to be used in place of fine-grinding mills normally required for quality XRD analysis. A secondary benefit is that it offers a simple means of loading and removal of samples, with potentially no moving parts. This research will answer a critical need for sample handling devices for conducting definitive mineralogical analyses in the Solar System. The Phase 2 effort will focus on addressing key technical issues in the development of a miniature Vibrating Powder Handling System. This work will lead to a brassboard prototype that can be remotely operated and interfaced to a planetary XRD instrument.
