Abstract

Chapter 7.5 discusses the effects of statistical fluctuation on the measurement of diffracted intensities. Fixed-time counting and fixed-count timing are compared. Complicating factors, such as detector dead time and source fluctuations are analyzed. The problem of measured-as-negative intensities is discussed, and strategies for optimization of counting time are analyzed.
