CONSTRUCTION OF A DOUBLE-RADIUS GUINIER DIFFRACTOMETER USING MO K-ALPHA(1) RADIATION AND A ONE-DIMENSIONAL OR 2-DIMENSIONAL DETECTION SYSTEM

This paper presents the design for a computer-assisted double-radius G uinier system for Mo K alpha(1), radiation with a cylindrically bent i maging plate and an integrated readout scanner for the recorded diffra ction patterns. This quick X-ray detection technique makes new applica tions for the Guinier method possible. The addition of suitable compon ents such as an optimized monochromator, a set-up for changing, moving and heating the samples and sophisticated adjustment equipment improv es the diffractometer, making it a competitive in-house system for pow der characterization and crystal structure determination of high stand ard. The commonly used scintillation tube arrangement should also be a dapted to receive a multifunctional system.
