The OSIRIS Project will explore the instrumental horizons available with the cold neutrons from a pulsed source and especially the totally new avenues available to polarised neutrons on these sources. On pulsed sources, polarisation techniques offer great potential for high resolution studies, and only lack of opportunity has left the field unexploited. On OSIRIS, the fundamentally novel methods developed on IRIS will be combined with proven and extended neutron polarising techniques. The high flux available at ISIS, coupled to the advanced design of the OSIRIS guide, will provide the means to take this field to its next evolutionary stage. By exploiting the combination of sharp pulses, white beams and cold neutrons from ISIS, high resolution measurements, both dynamic and structural, can be carried out using both unpolarised and polarised neutrons.
