Graduate Student, University of Tennessee - Knoxville
John Hirtz is a graduate student at the University of Tennessee Knoxville. His research focus is on the effect of dense electronic excitation from swift heavy ion irradiation on material structure and properties at extreme conditions. Current research includes pressurized molecular gases, including CO2, N2, and H2; as well as, implanted He bubbles in nuclear fuel surrogate materials. Research activities are conducted through collaborations with GSI Helmholtz [sample irradiations] and Lawrence Livermore National Laboratory [Helium Implantation]. Sample characterization techniques are performed at the HPCAT Beamline at the Advanced photon source located at Argonne National Laboratory. This work aligns with CDAC Science Thrust 5: Defects and Ion Irradiation.
