    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...
