Carbon NanoTubes (CNT) have been known for a couple of decades, but the understanding of their behaviour and their use is only now starting to develop. This allotropic form of carbon has extraordinary high inherent properties and has huge potential to play a major role in our future society. A CNT consists of a single or several sheets of graphene, coiled on themselves. The diameter of these tubular structures varies from 1 to 10 nanometers and the length can reach 1 meter. The amazing characteristics of this material have not been exploited due to the difficulties of manipulating this nanoscale material. However, the extraordinary and unique properties of this material have very interesting potentials applications in fields as varied as mechanics, electronics, optics and even medicine. At CERN, research has started to explore the use of CNT’s as an alternative to the carbon fiber used in wire-scanners to measure the beam profile, which will be incompatible with the high intensity and smaller beam sizes of future projects.
