    We demonstrate the use of simulations in the process of determiningthe optimal instrument setup by virtual experiments usingthe simulation package McStas. The focus of the analysis is the optimization of the multi-blade analyzer present at the RITA-II spectrometer at PSI for a test experiment with powder diffraction. The agreement in resolution and signal-to-background ratio between measurements and simulations shows the validity of the approach. For a sample with broadened Bragg peaks, the optimal instrument configuration could be established only on careful consideration. This shows that in general instrument simulations are approaching a state where they can assist users in selectingthe optimal configuration and possibly demonstrate the feasibility of their experiments prior to allocated beamtime.
