Canted in-vacuum undulator (IVU21) with 21 mm period, 1.5 m long. Inserted into the 17-ID low-beta short straight, the AMX IVU21 is canted outboard by 1mrad and upstream of the identical FMX IVU21 which is canted inboard by 1 mrad.
White beam slits, double crystal Si (111) monochromator with horizontal theta-axis, tandem flat beam deflecting silicon mirrors (Pd and Si lanes), Kirkpatrick-Baez focusing silica mirrors, Pd coated, each bent adaptively with 16 piezo actuators. Each optical element is preceded by slits and its transmitted beam is monitored by beam position monitors or retractable screens.
High-precision horizontal axis goniometer for data collection from cryogenic specimen, exchangeable with a secondary goniometer for data collection at room temperature from specimen in crystallization plates, on-axis reflective optics microscope, dynamical beam shaping slits, six-axis sample changing robot with high capacity specimen dewar, Pilatus 6M pixel-array detector framing at up to 25 Hz.
