Endstation 1 (ES1): A Stoe Stadivari 4-circle single crystal diffractometer combined with a Research Detectors Inc. (RDI) CMOS 1M detector serves as the primary instrumentation. The sample position is equipped with actively corrected xyz stages for aligning and maintaining samples weighing up to 1 kg on the 10 µm sphere of rotation. The CMOS detector is optimized for 25 keV X-rays, and is capable of collecting data at 20 Hz. The entire diffractometer assembly can be aligned on the beam using two Aerotech stages, which deliver transverse and vertical translation. A compact collimator allows the user to use a small the beam matching their experiment, as well as enabling raster scanning for sample location.
Endstation 2 (ES2): The secondary focus point is optimized for powder X-ray diffraction in combination with in-situ laser heating. A single vertical rotation axis (ϕ) sitting on a xyz stage stack serves as the point of reference for the sample position. The sample is positioned onto the rotation axis with a second xyz stage on top of the ϕ axis. This set-up also serves as ad-hoc single crystal set up. A Mar345 image plate and Pilatus3 S 1M detectors serve as X-ray detectors. More on our detectors can be found here.
