As with all other experiments you need to have a good plan of action before you arrive. Most of this will be in your application for beam time already, but even though you have done neutron diffraction experiments before, some things are particular to OSIRIS. Since we do not measure the whole diffractogramme in one measurement but normally a range of 2Å (in d-spacing) at a time see table d-range, you can choose if you want better statistics in one particular range. The standard ranges can be found in table d-range. If you want to use other ranges please contact you local contact before the experiment. It helps if you have thought through how small errors you want to achieve when deciding how long to measure on each d-range setting.
There are only detectors in backscattering position, so if you want to measure out to very long d-spacing you will be using very long wave-length neutrons. You will have very good resolution but if the sample is highly absorbing the long wave-lengths will mean that you have very high absorption.
If you want us to supply you with the sample can, please let us know in advance how many and what size of can you need.
When you arrive at ISIS you should:
