[alpha]-quartz has been irradiated with heavy ions: [sup 19]F, [sup 32]S, and [sup 63]Cu at an energy of about 1 MeV/amu in order to cover a range of electronic stopping powers [ital dE]/[ital dx] between 2.4 and 9 keV/nm and [sup 58]Ni, [sup 86]Kr, [sup 128]Te, [sup 129]Xe, [sup 181]Ta, and [sup 208]Pb between 1 and 5.8 MeV/amu for [ital dE]/[ital dx][gt]7 keV/nm. The extent of the induced damage is determined using Rutherford backscattering ion channeling with a 2-MeV [sup 4]He beam. The damage cross section [ital A] is obtained using a Poisson law [ital F][sub [ital d]]=1[minus]exp([minus][ital A][phi][ital t]), where [phi] is the flux and [ital t] the irradiation time. This damage cross section is linked to the effective radius [ital R][sub [ital e]] through the relation [ital A]=[pi][ital R][sub [ital e]][sup 2], where [ital R][sub [ital e]] is the radius of an equivalent cylinder of damage. Using high-resolution electron microscopy, cylinders of amorphous matter have been observed, whose radius corresponds to [ital R][sub [ital e]] when the track is continuous (i.e., for [ital A][ge]1.3[times]10[sup [minus]13] cm[sup 2]; [ital R][sub [ital e]][ge]2 nm). A thermal-spike model is applied to calculate the radii of the observed tracks assuming that the observed amorphous cylinders correspond to a rapid quench of a molten liquid phase along the ion path. The model is applied only when the latent track is continuous and cylindrical. A good agreement is obtained taking into account that the initial spatial energy deposition on the electrons depends on the ion velocity.
