Considerations Concerning the Experiment

  • Michael Leitner
Part of the Springer Theses book series (Springer Theses)


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.
