A window allows the introduction of radiation energy into an annular processing chamber (44) filled with a material to be processed. The chamber is formed from coaxial cylinder members (30,32) rapidly rotating relative to one another. The chamber (44) can be thin enough so that it is short compared to the penetration depth of the radiation through the material, providing even exposure of the material to the radiation. Also, eddies created in the material by the relative rotation enhances the even exposure. When the material inside the annular processing chamber (44) is opaque, resulting in an insignificant penetration depth, the eddies still insure that the material is evenly exposed to the irradiation.

L'invention concerne une fenêtre permettant d'introduire de l'énergie de rayonnement dans une chambre de traitement annulaire remplie d'une matière à traiter. La chambre est formée d'éléments cylindriques coaxiaux tournant rapidement les uns par rapport aux autres. La chambre peut être assez mince de façon à être de faible dimension par rapport à la profondeur de pénétration du rayonnement à travers la matière, permettant ainsi d'exposer la matière au rayonnement de manière uniforme. Les fluctuations créées dans la matière par la rotation relative permettent d'obtenir une meilleure uniformité d'exposition. Lorsque la matière à l'intérieur de la chambre de traitement annulaire est opaque, résultant en une profondeur de pénétration insignifiante, les fluctuations garantissent quand même l'exposition uniforme de la matière au rayonnement.
