1. A system for cooling multiple single-type window foils of an electron beam accelerator comprising:

  • a primary single-type window foil communicating with a vacuum side of a scanning horn of the electron beam accelerator;

    a secondary single-type window foil positioned on an atmospheric side of the scanning horn, wherein the distance of the secondary window to a biomass material under irradiation is more than 0.1 cm and less than 10 cm;

    a first flow path for providing a first cooling gas across the primary single-type window foil and second flow path for providing a second cooling gas across the secondary single-type window foil, the secondary single-type window foil being exposed to atmospheric pressure;

    a pivoting beam stop configured to pivot between the primary single-type window and the secondary single-type window to block an electron beam of the accelerator;

    a conveyor that is configured to move the biomass material through an irradiation zone under the secondary single-type window foil;

    wherein the primary and secondary single-type window foils are positioned with a gap of less than about 9 cm between them.
