Panorama of the UW-Madison IBL facility

The Ion Beam Laboratory (IBL) at the University of Wisconsin, Madison houses an NEC 1.7 MV tandem accelerator with two ion sources and three beamlines. IBL can provide different purposes of irradiations and in-situ measurements. The facility’s capabilities are continually improved to meet the research needs of the scientific community involved in research on radiation damage of materials and other fundamental materials science research areas involving ion irradiation.

Prof. Couet co-manages the IBL with Prof. Sridharan while Kim Kriewaldt is the Laboratory Technician and Hongliang Zhang the Scientific Manager and Point of Contact. Prof. Couet’s research group is highly involved in the IBL development. For instance, Zefeng Yu developed a new proton beamline stage with liquid metal cooling and IR camera in-situ temperature monitoring. Michael Moorehead developed a high-throughput automated sample stage with high-temperature capabilities in collaboration with Hongliang Zhang to study irradiation damage in additively manufactured high-entropy alloys. Calvin Parkin is also using the high-throughput stage to study irradiation damage in combinatorial thin films of compositionally complex alloys.

Here are some photos of the IBL facility
