Canadian Neutron and Positron Beam Laboratory

McMaster University, Hamilton, Ontario
What the facility does

Research establishing structure-function relationships in a broad range of new materials.

Areas of expertise

The Canadian Neutron and Positron Beam Laboratory carries out neutron diffraction measurements on materials, as a function of temperature and other environmental conditions. These measurements are carried out at wide diffraction angles to characterize structure on the angstrom level, and at small angles to characterize structure on the nanoscale and 10s of nanometer scale. Neutron diffraction is similar to x-ray diffraction, but with several distinct advantages. In particular, neutron diffraction can highlight hydrogen and other light elements within structures and is the most powerful probe of magnetism in solids.

Specialized lab EquipmentFunction
MAD: the McMaster Alignment DiffractometerTriple axis neutron spectrometer (custom designed and built)The spectrometer has a fixed monochromator angle and an Eulerian cradle for supporting and aligning heavy sample environments. Allows for neutron diffraction studies at wide angles of materials in single crystal and powder form, as a function of temperature and other environmental conditions.
MacSANS: the McMaster Small Angle Neutron Scattering InstrumentSmall angle neutron diffractometer (custom designed and built)Employs a large 1m x 1m position sensitive detector and velocity selector. Optimized for structural studies on materials in the 0.5–100 nm range. Allows for neutron diffraction studies at small angles of materials in single crystal, powder form, as well as in liquid state and complex fluid forms.  Measurements can be conducted as a function of temperature and other environmental conditions.
