Well yes Angus :-) For the past 30+ years ILL has stored all instrument data as simple ASCII files with a data format described in the first few lines of the file. ASCII was chosen because it will survive generations of computer hardware and operating systems, because it is human readable, and because it compresses well if you need to do that. Neutron sources can afford to keep almost all data, but this is often not possible for data from high flux synchrotron sources. Fortunately (?) data storage capacities have grown much faster than neutron intensities and data volume. There are working groups and conferences on this subject, so I am copying this to our local expert if you want to follow it up. Alan.
