Funding: This work is supported by the US National Institutes of Health and the US Department of Energy. We present the final engineering design and first commissioning results of two highly integrated experimental stations for the micro-focusing (FMX) and the highly automated (AMX) MX beamlines at the NSLS-II. These beamlines will support a broad range of biomedical structure determination methods. The experimental stations are designed and fabricated in-house to meet the challenging requirements resulting from the small beam size of 1 µm and the extremely short working distance of only 190 mm from the beam exit window to the FMX focal spot. The compact beam conditioning unit contains, within 140 mm, a beam position monitor, an attenuator, primary slits, an intensity monitor, a sub-millisecond shutter, and secondary slits. The diffractometers consist of an interchangeable dual axis air bearing-based goniometers with a target sphere of confusion of 100 nm, an on-axis microscope, an x-ray fluorescence detector and dynamic beam shaping slits. The end stations are integrated in a compact space on a granite machine bed with high modularity for future upgrades and extensions. Real-time autonomous robotic systems are being implemented for high through-put cryogenic sample handling. |
