The Brockhouse beamlines share several sample environments, including:
  • Cryostream: temperature control from 80-500K
  • Helium Cryostat: enables experiments down to 10K (-263 ºC)
  • High Temperature Flow Cell: temperatures up to 1070K (+800 ºC) with gas flow for capillary format samples
  • Dual-Sample High Temperature Flow Cell: emperatures up to 1273K (+1000 ºC) with gas flow for samples in capillary format (two can be loaded at a time)
  • IBM Endstation: temperatures up to 1000ºC with rapid thermal annealing (RTA), ultra-high purity N2 or He, and in-situ electric resistance probes and roughness measurements, all while measuring XRD.
