Abstract

Swift heavy ions induce a Gaussian temperature distribution Θ(r) in insulators which depend neither on the physical properties of the solid nor on the kind of the projectiles. In this paper, we show that all experimental data suitable for analysis confirm the validity of Θ(r). The same result is obtained for ZrSiO4, MgAl2O4, KTiOPO4, Al2O3 and Y2O3, where systematic experiments have not been performed yet. The analysis demonstrates that Θ(r) may be valid in biomolecular targets and in high-Tc superconductors as well. The Fourier equation cannot reproduce the relation Θ(r); thus, it is not suitable for the estimation of the ion-induced temperatures. The consequences of the uniformity in track formation must also affect other radiation-induced effects.
