inexpensive detectors

2014-02-10 Thread peterson
Hi everyone, Not really a Rietveld question but I thought this group would be good to askĀ… As a mineralogist we have used Gandolfi cameras in the past to identify small amounts of unknown mineral mixtures. The camera mechanism randomizes the orientation of the small single crystal or crystal aggre
