The heart of this facility is a state of the art instrument for ultra-small to wide angle X-ray scattering. The Xeuss 2.0 from Xenocs permits characterization over length scales from 0.09 nm to 600 nm and thus facilitates study of hierarchical structures in a wide range of hard and soft materials. Features and capabilities include:
- Dual copper and molybdenum X-ray sources.
- Dual detectors: a 1M Pilatus solid state detector for small angle scattering, and a 100K Dectris detector for scattering up to 45°.
- Adjustable sample-to-detector distance between 15 cm and 6 meters.
- Measurements in transmission or grazing incidence configuration.
- Temperature-dependent measurements between -50°C and +350 °C.
- Tensile stage.
- Low-noise flow cell for dilute aqueous suspensions.
- Simultaneous control of temperature and humidity.
The facility is available to Penn faculty, staff, and students, and to outside users on an hourly fee basis.
Non-Penn academic users: $60/hour
Non-academic users: $300/hour or $3000/24-hour day
There is no charge for initial training
