Piercing polymers with single ions

Ion tracks provide a new route to micro and nano technology. A mobile irradiation system is used to pierce polymer films with a preset number of energetic ions down to one single ion. The mobile irradiation system is installed at the beam port of a heavy ion accelerator. After the ion has passed through the polymer it is detected and triggers a beam shutter. The polymer tape is marked and transported by a fixed length for the next irradiation. Click on thumbnails for details.
