SHIM 2015 Swift Heavy Ions in Matter

The nature and intensity of ion-surface interactions are intimately connected to projectile energy deposition in the target and therefore depend both on the kinetic and the potential energies [1]. The energy losses of swift heavy ions (SHI, MeV to GeV) induce along the ion path intense electronic excitations in a small volume which spawn formation of surface modifications and latent tracks in...

In this study, CeO2 and NiO were irradiated with Au ions in the energy range of 200-340 MeV at oblique incidence. Observation of as-irradiated samples by transmission electron microscope (TEM) shows that hillocks are created not only at the wide faces but also at the crack faces of thin samples. Since the hillocks created at the crack faces can be imaged by TEM, their shape and...

Y-Ti oxides and Me23C6 precipitates are typical representatives of nanoparticle population in ferritic oxide dispersion strengthened (ODS) steels. Their stability during dense ionization in the so-called swift heavy ion regime has received considerable attention in recent years because the change in nanoparticle morphology should inevitably affect the mechanical properties of the first few...

Research on materials under coupled extreme conditions including pressure, temperature, and irradiation has become a new and vibrant area of investigation [1]. Incorporation of relativistic ion beams, in particular, has proven effective for synthesis and stabilization of novel phases far from thermodynamic equilibrium [2]. The technique couples static compression and high-density energy...
