Industrial applications of pulsed particle beams and pulsed power technologies

In close collaboration with government, municipality and private companies, the systematic studies on pulsed power technology have been carried out at Extreme Energy-Density Research Institute (EDI), Nagaoka University of Technology. In particular, the applications are emphasized to materials science by intense, pulsed ion beam evaporation (IBE) using high-density ablation plasma. Various kinds of thin films or ultrafine nanosized powders have been prepared very efficiently. Additionally, the nanosized powders can be successfully synthesized by pulsed wire discharge (PWD) as well. The industrial applications have also been succeeded in NO_x treatment by an intense, pulsed relativistic electron beam (IREB) or pulsed corona discharge using an inductive-energy-storage (IES) pulsed power generator. Recent progress at EDI will be overviewed.
