Description
Summary:Linear accelerators of various types are now at the threshold of commercial exploitation in radiation processing. A recent design study has confirmed that continuous wave linacs, proposed at the previous conference in this series, can be built with existing technology. In a design study of a 10 MeV, 50 mA machine a frequency of 2.45 GHz was selected, following an examination of klystron availability, structure efficiency and system physical size. The underlying physics is modeled on the performance of the Electron Test Accelerator presently operating at Chalk River. Concurrently, a simple calorimetric experiment, carried out at the National Research Council's linac in Ottawa, measured bremsstrahlung yields at 10 MeV that are somewhat higher than yields derived from Monte Carlo calculations. Some details of the experiment will be given and together with the features presented for other types of linacs, the paper summarizes the main technical parameters which determine source efficiency.
