Three technologies developed for use at the U.S. Department of Energy's Advanced Photon Source (APS) at Argonne National Laboratory have won R&D 100 awards. The awards are given annually by R&D Magazine to the 100 most significant technical products of the year.

During the two-week period of August 14-26, 2000 Argonne National Laboratory once again hosted the National School on Neutron and X-Ray Scattering funded by the Office of Basic Energy Science of the Department of Energy.
