In this paper the design and detailed qualification process of an industrial irradiator based on an 125 10 MeV TT–100 Rhodotron electron accelerator is presented. The system provides 2 beam lines: a 10 MeV mono-energetic electron beam line and a 6.6 X-ray source using a tantalum target. The system is designed to provide a wide range of doses with very high precision which are required e.g., for advanced applications in medical device sterilisation or semiconductor modification. The paper focuses on the design process which includes 3D mathematical modelling and the extensive validation program including IQ, OQ and PQ. Preliminary results of the characterisation of the radiation field are presented together with comparison between model predictions and dosimetry.
