Summary on Grant Application Form
Through a collaboration between Edinburgh University and Universit Paris VI, supported by RAL, a breakthrough has been achieved recently in neutron powder diffraction at high pressure, using the ISIS pulsed source. The longstanding limit of ~30 kbar for all neutron techniques has been extended to well over 100 Kbar, and work is in hand to reach the design limit of 160-200 kbar and introduce temperature variation over a modest range of about 120-400K. The success of this first stage has made it clear that it is feasible to reach a considerably greater range of P and T, and it is now proposed to develop new instrumentation at ISIS for work to 400-500 kbar from 100 to 400K, and to above 150 kbar down to 20K and up to 1000K or more. Such extensions will make the crucial step from a successful pilot project to the establishment of neutron scattering as a major technique in the high profile field of high pressure science and technology, and open up many entirely new and exciting areas of neutron-beam research in structures and transitions, magnetism, materials science and earth science. The new facilities will be used to pursue a core science programme including transitions and structural P- dependence in fundamental molecular systems, semiconductors, boron-rich solids and high Tc superconductors. In addition, the facilities have a large potential user community from the UK, Europe and around the world with research programmes ranging across the physical, materials and earth sciences. In short, a major new field of forefront neutron-beam research will be established for which ISIS will be the world centre
