Simulated experiment The white beam (polychromatic) from the thermal tube H11 arrives at the monochromator. Monochromatic diffracted beams reache the sample – a single crystal - located at the centre of ... Eulerian cradle. The curved two-dimensional position-sensitive detector (PSD) records all diffracted beams within its angular range (120° × ...
