Summary on Grant Application Form |

We propose to use neutron transmission measurements to determine a two dimensional map of the stress free lattice parameter across component slices, at high rates of data acquisition. this technique promises a major breakthrough for measurements where there may be a spatial variation in the stress free lattice parameter: e.g. for weldments (easily the most popular type of problem currently tackled by neutron diffraction). At present, such measurements can only be obtained by time-consuming sectioning of the test-piece into small stress-free parts.The development of the necessary pixellated transmission instrument will also open up applications in many other materials areas: e.g. the speed of data acquisition will enable structural information to be recorded for time-dependent behaviour, such as ageing and thermal cycling.A simple prototype transmission detector has already been tested the ENGIN instrument at ISIS. Through this proposal we aim to build a dedicated, pixellated transmission detector array with a spatial resolution of 2mm, and to develop the necessary data analysis software to enable `Rietveld' style analysis of the transmission spectra.
