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 (would it get beam time)
