Electrons, Neutrons and X-rays: The emphasis here is on polymers, proteins and other complex systems.

X-ray diffraction

Source Description
Daresbury Synchrotron Lab - Small molecule and powder diffractometry links The Daresbury Lab is the major synchrotron source in the UK, it is organized into discrete project areas. Area 14 deals with single crystal and powder diffraction.

Neutron Diffraction and Scattering

Source Description
Los Alamos Neutron Science Center The Los Alamos Neutron Science Center, a national user facility that produces intense sources of pulsed protons and spallation neutrons for defense and civilian research and applications. LANSCE is ideal for research in condensed-matter science and engineering, accelerator science, nuclear physics, and radiography.
Oak Ridge National Laboratory The High Flux Isotope Reactor (hfiR) at the Oak Ridge National Laboratory (ORNL) operates at a power level of 85 MW and produces a maximum neutron flux of 3x1015 cm-2s-1 in its central flux trap. The neutron scattering facilities at the HFIR, which have been constructed and operated with support from the US Department of Energy, are available for outside use on problems of scientific merit. Oak Ridge will also be the site for the accelerator-based Spallation Neutron Source and the ORNL/University of Tennessee Joint Institute for Neutron Sciences.
The Institute Laue Langevin The ILL is a fundamental research institute operating a high-flux reactor with many experimental facilities. These instruments are available in user operation to scientists coming from research laboratories in the member countries: France, Germany, United Kingdon, and the associated members: Spain, Switzerland, Austria, Russia and Italy. Experimental proposals are examined twice a year by the scientific council, a body consisting of specialists from different countries. Invitations for accepted experiments are issued several weeks before the start of the measurement. The measurement time varies between a day and several weeks.
