Each group should aim to provide feedback to the other groups on their proposals, identifying strong/weak points in the
- presentation
- scientific background and justification
- justification of neutron imaging method and beamline
- description of experiment
- discussion on what will be the outcome of the experiment (including how the data might be analysed)
- over all rating of proposal...
