Experimental Techniques

I05 ARPES beamline at Diamond Light Source, UK used for electronic structure measurements
ESRF Synchnotron and ILL Neutron Source in Grenoble, France both used to probe the structure, excitations and dynamics of the materials we create.
Target Station 1 at the ISIS Neutron and Muon Source, UK, we use elastic (wide and small angle), inelastic, quasi-elastic and muon spectroscopy.
High speed AFM at Bristol built by Oliver Payton and Loren Picco
Titan electron microscope at Imperial College London
Physical Properties Measurement System, used to measure AC magnetistaion, resistivity and heat capacity as a function of field and temperature
Magnetic Properties Measurement System, used to measure DC magnetistaion as a function of field and temperature
'Low temperature' UHV Scanning Tunnelling Microscope at the London Centre for Nanotechnology
The incredible resonant inelastic X-ray scattering I21 beamline at Diamond light source.
The NIMROD neutron diffractometer dectector bank at TS2 at ISIS Neutron and Muon Source, capable of measuring over an enormous Q-range for small and wide angle measurements. We use this machine, in combination with modelling-based refinement of diffraction data to study local and long range order in liquids.
