The following two major XRD instruments have been installed in the CharFac's Shepherd Labs basement facility. Please contact the Drs. Javier G. Barriocanal or Seema Thakral to discuss instrument capabilities. (Click on Staff link for contact information)
Rigaku Smartlab XE
A high resolution six-circle diffractometer ideal for the study of thin-films, single crystal and powder samples that would require angular resolutions as small as 0.005℃. Special features
- Numerous options to select among pre-sample and post sample optics, sample stages and detector modes
- Suitable for applications such as XRR / HRXRD / RSM / In-plane XRD / PF / HRPD / µ-XRD
- Cu sealed X-ray tube and a HyPix-3000 two dimensional detector. The detector has a maximum count rate of at least 108 cps/mm2 and a 15% energy resolution to reject spurious signals, reducing the overall background of the measurements and increasing the outstanding dynamic range of detection.
- Non-ambient stages to conduct in operando measurements from -180 C to 1100 ℃ in various environments.
Rigaku Smartlab SE
The instrument is configured as a powder diffractometer with Bragg-Brentano optics, copper X-ray sealed tube, computer controlled variable divergence slit and the D/teX Ultra one-dimensional detector. It will house the third non-ambient sample stage: the Oxford Cryosystems PheniX cryostat. This closed loop He cryostat allows a temperature range of measurement from 12 K to 290 K without consumables and is perfect for crystallographic studies of organics, inorganics, drugs, minerals and other materials at very low temperatures.
