Formation of a PRT and the instrumentation of x-ray diffraction on the NSLS. Progress report, September 1, 1980-October 30, 1981

The Midwest Analytical Team for Research Instrumentation of X-Rays (MATRIX) was organized to formulate a research team to design, construct and utilize a port at NSLS for diffuse scattering. MATRIX, which was formally initiated in September of 1980 upon receipt of funding, consists of active members from Purdue University, Northwestern University, University of Illinois, Iowa State University, Michigan Technological University, University of Missouri, and Argonne National Laboratories. The Executive Committee and all design teams have met three times with two other meetings scheduled for 1981. The first year's design phase is near completion and has concentrated around the diffractometer system, beam line, and computer control system. Some changes which have influenced the design progress are the addition of a full time design person and the inclusion of added expertise in our design teams. These changes have accelerated our progress beyond the state originally estimated. These factors have made it possible to advance some aspects of our design, in particular, the monochromator-mirror design which had been reserved for the second year. The final design phase is expected to be completed in early 1982 with installation in late summer of 1982. Initial research on local atomic arrangements and lattice effects will then be initiated
