[19] Diffraction-data processing for electronic detectors: Theory and practice.

Publisher Summary With the advent of electronic area detectors, software was developed both to drive data acquisition and to process their data. This method was developed originally for data collection with X-ray film and is being used almost universally. The geometry is simple—a crystal is rotated around a single axis, while a detector remains fixed. The main feature to distinguish electronic area detectors from film and imaging-plate detectors is the readout time. Electronic detectors have a relatively fast readout, so in any given experiment, a smaller volume of reciprocal space can be sampled on each image without the ratio of readout time to exposure time becoming significant. The chapter describes a general philosophy for the collection and analysis of images from two-dimensional position-sensitive detectors. The chapter focuses on the MADNES software package and on integrating detectors, such as the CCD-based detectors described by Westbrook.
