Radiation Dynamics, Inc. (RDI), currently a wholly‐owned subsidiary of Ion Beam Applications (IBA), has supplied particle accelerators for both research and industrial applications worldwide for almost 50 years. The industrial market demands are driving the development of a new Dynamitron® system with a smaller, more compact configuration that may be provided at a lower entry cost. This new system, operating at electron energies up to 1.0 MeV, includes integral shielding, which allows the appropriate material handling system to be installed inside the radiation enclosure. Designed to operate with beam power levels as high as 100 kW, this new system provides a robust base for high‐throughput crosslinking of products such as electrical wire, heat‐shrinkable plastic tubing and sheet materials. Still retaining the positive aspects of the current Dynamitron system that have established it firmly in the industrial sector, this compact system can be tailored to meet a variety of processing applications. © 2003 American Institute of Physics
