Provided is an electron beam irradiating device capable of emitting an electron beam from an electron beam generation source surrounded by a vacuum chamber to outside of the vacuum chamber through an electron beam exit window. The electron beam exit window includes: a grid; a window foil allowing the electron beam to pass therethrough; and a frame-shaped pressing member pressing the window foil against the grid. The surface of the grid has a groove section having an annular shape. A metal gasket is pressed between the groove section and the window foil.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the equipment is protected from radiation and hazardous gases by equipment enclosures. The equipment enclosures may be purged with gas.

Methods and systems are described for processing cellulosic and lignocellulosic materials into useful intermediates and products, such as energy and fuels. For example, conveying systems and methods, such as highly efficient vibratory conveyors, are described for the processing of the cellulosic and lignocellulosic materials.

For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, while cooling equipment and the biomass to prevent overheating and possible distortion and/or degradation. The biomass is conveyed by a conveyor, which conveys the biomass under an electron beam from an electron beam accelerator. The conveyor can be cooled with cooling fluid. The conveyor can also vibrate to facilitate exposure to the electron beam. The conveyor can be configured as a trough that can be optionally cooled.

A method for assembling an electron exit window of an electron beam generating device comprises arranging a foil support plate on a housing of the electron beam generating device, bonding a window foil to a frame along at least one continuous bonding line, thus creating an exit window sub-assembly, and attaching the exit window sub-assembly onto the housing.
