    **PSI Ring Turnseparation**
    ====================
    The PSI Ring parameters are not well-known. The goal of this study is to find good simulation parameters that match the measurements. As objectives we use the radial turn locations. As optimisation parameters we use the injection angle, radius, energy and radial momentum.
    The OPAL probe code has been extended to find the radial turn locations in the same way as in the measurement, see figure below.
