The General Purpose Table is a dedicated end-station for angle-dispersive micro-x-ray diffraction of samples in a diamond anvil cell.

Capabilities include:

• Powder, polycrystalline and single-crystal techniques
• Axial and radial geometries
• Mechanical, pneumatic, and piezoelectric pressure control
• Cryogenic cooling down to ~15 K (~4 K with large cryostat)
• Whole-cell (resistive) heating up to ~800 K
• Static and time-resolved measurements
• Online ruby and optical microscopes

Additional features and specific configuration choices include:

• Si(111), Si(220), and Ge(111) monochromator crystals with an energy range ~18-50 keV
• Large and small KB focusing assemblies for highest flux and highest spatial resolution, respectively
• Clean-up pinholes from 10-150+ microns
• Hybrid sample stack that can accommodate up to 30 kg payload with micron precision
• Beamstop with integrated photodiode
• PILATUS3 X 2M CdTe detector (1 mm CdTe sensor, 250/500 Hz full-frame/ROI imaging frequency)
• Complementary software for rapid, 2D, on-the-fly transmission and/or x-ray diffraction imaging
• Flexible end-station design to accommodate special experimental configurations
