Laboratory X-ray Powder Diffraction
Laboratory diffractometers form the introduction to powder diffraction for most researchers. On a basic level for phase ID, etc., one diffractometer is very much like another. However when configuring a system for more challenging and advanced experiments, a variety of options and choices confront the experimentalist. Rather than cover the basics of diffractometer operation and geometry we will discover how a good understanding of the concepts behind laboratory diffractometers and their components is vital to getting the best from a system and pushing the limits of what can be achieved with lab instrumentation. Laboratory instrumentation will never compete with the sheer power and resolution of a synchrotron beamline. However, by departing from the conventional setups, it can be surprising what may be achieved in-house without resorting to the delay and inconvenience of synchrotron beamtime proposals.
