Popis:	The penetrating nature of the photons produced by the X-ray (bremsstrahlung) process makes them attractive for the treatment of dense materials in industrial radiation processing. The inefficiency of the conversion process can be balanced by the exposure of high Z materials to electrons with high energy. However, activation of the product being irradiated and the equipment imposes energy limits. Results of a theoretical and experimental study to investigate the key parameters have resulted in recommendations for the design of X-ray converters in the electron energy range 7 to 11 MeV. Results of the Monte Carlo calculations and the methods used in conversion experiments with the 50 kW IMPELA accelerator are reported.
