Abstract
Methods and systems are described for processing cellulosic and lignocellulosic materials and useful intermediates and products, such as energy and fuels. For example, irradiating methods and systems are described to aid in the processing of the cellulosic and lignocellulosic materials. The electron beam accelerator has multiple windows foils and these foils are cooled with cooling gas. In one configuration a secondary foil is integral to the electron beam accelerator and in another configuration the secondary foil is part of the enclosure for the biomass conveying system.

A system for cooling multiple single-type window foils of an electron beam accelerator comprising:
- a first flow path for providing a first cooling gas across a primary single-type window foil and second flow path for providing a second cooling gas across a 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.
A method for cooling multiple single-type window foils of an electron beam accelerator, the method comprising:
- passing a first cooling gas across a primary single-type window foil and passing a second cooling gas across a secondary single-type window foil, wherein
- the primary and secondary single-type window foils are positioned facing each other with a gap of less than about 9 cm between them.
