Carbon nanotubes have many unique and extreme physical properties for this reason they will playa key role in the next future of society. Many governments allover the world are investing great resources in nanotechnologies research activities. The reason is the great performances of nanostructured materials and the large variety of applications of these technologies. The objective of this proposal is to realize a new machinery based on a cheap technological procedure, the Channel Spark Ablation (CSA), to produce high quality single walled carbon nanotubes which should yield the same quality as laser ablation, but at much lower costs. The nanotubes produced by this equipment will be used as passive electronic elements into innovative solar cells and dye sensitised solar cells. The major innovation of the proposal IS the idea to adopt an innovative technology to provide single-walled nanotubes at first on the kilogram scale and ultimately on a tonne scale. The.CSA is a system based on the pulsed electron-beam generation from the glow-discharge plasma environment. The applicability of the CSA to nanotubes preparation relies on the high effective temperatures that can be reached at the target surface and on its similarities to Pulsed Laser Ablation. It is clear that the development of sophisticated equipment and its further adjustment required for different materials utilisation can not be tackled by an only company. The contribution of the RTD performers will be essential to avail the indispensable know-how and resources to overcome the theoretical and technical problems and so to get the final positive result. The economical reason of the trans-national cooperation is given by the great industrial interest, allover the Europe, for this new, promising technique for nanotubes mass production. Actually the most important limitation of the nanostructured materials is due to the high production cost mainly due to high energy consumption and low process pro
