Detailed studies of structures and regions from several centimetres to 50 micrometres. Availability Accelerator time is shared with other users, and requests for use must be made well in advance. XYZ Target Manipulator - UHV target chamber with charged particle detectors for depth profile measurements of light elements such as hydrogen, carbon and oxygen, using forward recoil and nuclear reaction techniques. This has a target positioning stage with precise 3D X, Y and Z movement. UHV Fluorine Analysis Facility Fluorine determinations for solid state and environmental studies.
Sensitivity is a few ppm for bulk fluorine content measurements.
Used for radiobiological studies of neutron induced damage in DNA, neutron irradiations of cereal crops. Samples are measured in vacuum and measurement of samples is can also be automated. External beam PIXE is also available for large samples but this needs to be set up for each new experiment and is only available on prior agreement. These techniques allow bulk element determinations to the parts per million concentrations, and the depth profiling of surface layers. The range of analyses possible covers elements from hydrogen to uranium.
