Description:

CANDOR Schematic

CANDOR Performance and Characteristics:

  • Q resolution, dQ/Q, ~0.025
  • Fractional wavelength resolution ~0.015
  • Angular resolution ranging from 1 to 10 minutes (of arc)
  • Significantly higher usable intensity incident on sample (expect more than an order of magnitude or more increase)
  • Background should not increase for a broader intensity beam wavelength band (assuming elastic scattering only) but may increase with an incident beam of greater angular divergence

What CANDOR . . .

. . . Should enable (conservative prediction)

  • Significantly shorter measurement times for a given sample size (or smaller sample volumes for a given data collection time)
  • Opportunities for measurements of structural evolution in real time

. . . Might enable (pushing the envelope)

  • The possibility of performing phase-sensitive specular NR measurements, which is the equivalent of one-dimensional real space imaging, in real time

Support

Refrigerators, furnaces, magnets, liquid cells, and lasers are available for control of sample environment. On-site x-ray reflectometry is available for additional sample characterization. If you're interested in performing an experiment, apply for beamtime, or contact one of the instrument scientists directly. Monetary assistance may be available for new facility users.
