The Synchrotron Topography Project (STP) has under design and construction various phases of a dedicated beam line for x-ray diffraction topography users in conjunction with the National Synchrotron Light Source at Brookhaven National Laboratory. During the past year final design and procurement phase has been completed for the following: (1) Experimental Hutch, (2) White Beam Camera, (3) Detector Arm for White Beam Camera, (4) Film Cassette System, (5) Medium Resolution Real-time TV System, (6) Lift Table Assembly, (7) Asymmetric Camera Base Mount, (8) Motor Control System, and (9) Computer system. Experimental work has been initiated on using reflection topography to study fracture surfaces. Preliminary results, both with Berg-Barrett, as well as with Synchrotron Topography done in collaboration with the Daresbury, U.K. facility show that defects generated in the near surface layers can be detected. Research work on the effects of stress concentration and geometric effects due to grain boundaries on the fracture of tungsten has been completed.
