Fig. 9.

CAD view of the elements with an influence on the particle trajectories of the STEP MC: the segmented detector is coloured reddish. The pinhole structure is black/beige. The magnets are illustrated in grey while the yokes of the magnets are purple. The orientation of each magnetic field is indicated with orange arrows. The front apertures are not shown. The structure of the IC is similar, but without the magnets and their yokes.
