Neutron Imaging Techniques and Methods

There are several possibilities how neutron imaging can be used for non-destructive evaluation. Single radiographs or 3D data delivering acquisitions using neutron tomography are applied to rigid objects or almost stationary processes. Dynamic processes e.g. humidity uptake or evaporation, investigations of running motors, etc. are investigated as time series of radiographs providing movies of the process. Contrast enhanced radiographs need neutron energy selective imaging methods and/or measuring techniques exploiting the neutrons wave properties as in differential phase contrast imaging. This wide range of imaging modalities requires different characteristics for neutron detector systems. Further information is given in the sections:
