New HEDM Project at ANL

Jocelyn Duffy

The National Science Foundation Major Research Infrastructure program announced funding of a $1.5M project to build a new High Energy Diffraction Microscope (HEDM) at the Advanced Photon Source (APS) synchrotron at Argonne National Laboratory. The project will be carried out by a consortium led by Robert M. Suter of the CMU Physics Department and involves faculty at Purdue University, Colorado School of Mines, and the University of Utah, as well as participants at the Advanced Photon Source.

This second generation instrument builds upon technological developments in which the CMU departments of Physics and of Materials Science and Engineering have taken a leading role for over more than a decade. Recent technology and software developments will allow enhanced experimental control and feedback as well as accelerated data reduction to produce microscope output on the time scale of the data collection. Once commissioned, the new instrument will be available to a broad international materials science community and help relieve the high demand on the current facility at the APS 1-ID beamline.
