Dr. Eric Lukosi

lukosi_1In order to achieve this ambitious goal, Lukosi and his team, including graduate student Thomas Wulz, are making use of advanced laboratory facilities and instrumentation at UT that include a hot wall Chemical Vapor Deposition system and a new Microelectronic and Thin Film Fabrication facility. They will be used to produce solid-state neutron imaging detectors that can perform at this level.

Recent funding from the National Science Foundation will support experimental investigations and modeling of a full-scale neutron imager and its full capabilities. So, as in many cutting-edge endeavors, both theory and experiment must work hand in hand to achieve success.

Lukosi’s investigations are focused on a corresponding LDRD project headed by Yong Yan at ORNL involving a broader inquiry into studies of zirconium alloy cladding under various physical conditions using both destructive and nondestructive analysis.

For Lukosi, this joint work affords the chance to build a long-term relationship at ORNL and the Spallation Neutron Source (SNS)* while undertaking neutron diagnostics at an advanced level. Because substantial funding will be required for the successful outcome of this challenging research, the project is only the beginning of many grant opportunities Lukosi is already on the path to pursue.

The ultimate result is expected to be a vastly improved neutron imager than what is currently available at SNS—not to mention a much safer world once fabrication of the detector is proven and leads to widespread use in critical applications.
