Considerations Concerning the Experiment

Chapter
Part of the Springer Theses book series (Springer Theses)

Abstract

In this chapter I will present some useful calculations for setting up the experiment. First the signal-to-noise ratio (the inverse of the relative standard error of the fitted correlation time) is computed as a function of the number of counts per pixel, the coherence factor, and the correlation time, leading to the identification of the product of intensity and coherence factor as the figure-of-merit. In the second section the optimization of the beamline set-up with regard to this figure-of-merit is discussed.

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
