Neutrons for Science
 neutron sources succeeding the ILL will certainly not be steady- state reactors. It will be very difficult if not impossible to improve the performance of these beyond the reactor of the ILL.
With this note we have finished with the pre-history and it
is time to look at how the verbal agreement at Geneva has materialised. Before this it is useful to look a little more closely at what can be done with neutron beams. The experiments of Shull and Wollan mentioned above were performed on a reactor which was not designed for this usage. The French-German project was for a reactor with a sole purpose to produce neutron beams, at a cost (in 2005 monetary terms) of €300M. Hence the justification for such expenditure needed a solid scientific case. This will be the theme of chapter 3 which the non-scientist reader may skip.
