1 RaDiate Collaboration Activities at BNL
Nick Simos, Mohamed Elbakhshwan BNL March 20, 2015

2 Summary of RECENT Activities
EDXRD vs. XRD of irradiated Graphite, Be and AlBeMet post-experiment analysis Preparation of three publications for submission to Journal of Nuclear Materials Submission of NSLS II XPD Beamline proposal for x-ray diffraction experiments that include irradiated graphite, C/C composites, Be, AlBeMet, Ti6Al4V, Glidcop and other super-alloys Hot lab re-arrangement and re-configuration. Dilatometer main processor “upgrade” Resistivity-conductivity fixture receipt. Implementation awaiting hot lab re-configuration finalization

3 Neutron-irradiated LBNE Graphite

4 EDXRD analysis of neutron irradiated POCO graphite using the “white beam” of X17B1 NSLS Beamline – 2-theta space Able to capture the primary peak associated with the inter-planar crystallographic direction and even lower where lattice imperfections, i.e. dislocations, are induced by irradiation)

6 Proton Irradiated Graphite

7 X-ray diffraction of irradiated POCO graphite using the “monochromatic” beam at X17A beamline of NSLS in D-spacing space. NOTE the greater detail of the crystallographic planes at the higher 2-theta as compared to the EDXRD but the inability to resolve the larger spacing between basal planes and the lattice imperfections.

8 Comparing EDXRD (white beam) and XRD (monochromatic) over the same space

9 EDXRD Experiment & Analysis of LBNE Irradiated Graphite and CC Composites
