Nuclear tracks are a logical extrapolation of the principles of cloud and bubble chamber onto solids. Besides their well-known application in particle detection, in solids a completely new aspect arises, the generation of extremely fine permanent tracks, which can be transformed into open channels. Nuclear tracks are therefore a unique single-particle structuring tool. Applications comprise (i) single hole membranes for particle counting and sizing, (ii) manufacture of microfilters with very uniform hole sizes; (iii) modification of' magneto-optic materials for application in display memories, and (iv) micromachining of surfaces.
