Claim:
1. A method comprising: impinging a substantially inert gas on a first foil window of an electron beam horn while passing electrons through the window and inert gas while processing a cellulosic or lignocellulosic biomass material in particulate form on a conveyor; while flowing the inert gas through an enclosed space defined by the foil window, which is in communication with a vacuum side of the electron beam horn, and a secondary foil disposed facing the first foil window under flow conditions that maintain the pressure inside the space between about 50 and 200 psi; treating the inert gas to remove contaminants produced during processing of the biomass material; and enzymatically saccharifying the processed biomass material to produce a sugar solution.
