A Photomultiplier Photometer for Studying Quartz Grain Orientation
Andrew L. Pierson, III
ABSTRACT
In this article an improved photometer for studying quartz grain orientation is described. The nonlinear illumination effects caused by a phototube having a cylindrical cathode and an axial wire anode have been eliminated in this new system by the use of an infrared sensitive photomultiplier tube with a flat photocathode. Because of this improvement, the preferential quartz grain orientation of many thin sections which could not be measured before can now be determined.
