“…This is illustrated by a recent prototypical study in hastening the detection of radiation void swelling, a key degradation mechanism as described in the Introduction. In 2018, Dennett et al (61) irradiated single crystal copper with 35 MeV self-ions, inducing void swelling as was clearly evidenced by TEM (see Fig. 5(c)).…”

“…These samples were chosen to extend the previous ex situ TGS work which was conducted on self-ion irradiated copper. 31 In that study, copper samples exposed at high temperatures were shown to exhibit microstructure evolution which could be correlated to changes in SAW speeds across all polarizations on a {111} surface. For in situ experiments, only one acoustic polarization may be sampled continuously during irradiation.…”

“…Such changes in elastic properties have been attributed to purely point defect concentrations 67 and larger-scale accumulated damage from continuous exposure. [29][30][31] In either case, foreknowledge of expected defect effects on acoustic characteristics allows for highly-resolved records of radiation-induced material evolution to be generated in situ.…”

“…TGS has proven a particularly useful tool for studying the properties of heterostructures [10] as well as short-wavelength, nonballistic heat transport in semiconductors [11]. Recently, TGS has become of particular interest in the study of the effects of ion irradiation on material properties, as the micron-scale excitations imposed can be tuned to match the length scale of imposed damage profiles [12][13][14][15]. Advances in time-resolved implementations of this and similar methods have drawn attention as potential in situ measurement tools given their ability to recover elastic and thermal properties using a non-contact and non-destructive methodology [16,17].…”
