Introduction to ion track technology

Ion tracks are created by swift heavy ions penetrating through solids.[1][2] They correspond to transformed zones >6 nanometer in diameter[3][4] and can be studied by Rutherford Backscattering Spectrometry (RBS),Transmission Electron Microscopy (TEM), Small-Angle Neutron Scattering (SANS), Small-Angle X-ray Scattering (SAXS) or gas permeation[5]. Ion tracks can be selectively etched in many insulating solids leading to cones or cylinders down to 8 nanometer in diameter.[6] In minerals, ion tracks can remain unaltered for millions of years. Their density tells about the time when the mineral has solidified from its melt and is used as a geological clock in fission track dating. Ion track technology deals with the application of ion tracks in micro- and nanotechnology.[7] Etched track cylinders can be used as filters,[8][9] Coulter counter apertures,[10] be modified with monolayers[11] or filled by electroplating[12][13].
