The AMX beamline layout (not to scale). AMX is served by the upstream (17-ID-1) IVU21 undulator, FMX by the downstream (17-ID-2) one. The beam of AMX is shown in red and that of FMX in blue. All distances are given with respect to the center of the short straight section, between the two undulators. The distance between the center of the AMX IVU and the center of the short straight section is 1.3 m.
