An electron beam device has a body provided with an exit window, said body is forming or is at least partly forming a vacuum chamber, the vacuum chamber comprising therein a cathode housing and at least one electron generating filament. At least one getter sheet is provided between the cathode housing and the filament. The invention is further comprising a getter sheet for use in an electron beam device and a method of manufacturing an electron beam device comprising at least one getter sheet.

Electron beam device, a getter sheet and a method of manufacturing an electron beam device provided with said getter sheet

An electron beam device having a tubular body of elongate shape with an electron exit window extending in the longitudinal direction of the tubular body. The tubular body is at least partly forming a vacuum chamber, the vacuum chamber comprising therein a cathode comprising a cathode housing having an elongate shape, and at least one electron generating filament and a control grid both extending along the elongate shape of the cathode housing. The control grid and the cathode housing are attached to each other by attachment mechanisms. Free longitudinal end portions of either the control grid or the cathode housing are bent in a direction towards each other to form bulge-like shapes for the formation of electron beam shaping electrodes. The invention is further comprising a method of manufacturing the electron beam device.

The present invention refers to a method for arranging a window foil to an electron exit window assembly of an electron beam generating device, comprises the steps of: arranging a foil support plate on a housing of the electron beam generating device, bonding a window foil to the foil support plate along a continuous bonding line, attaching a skirt of said window foil extending radially outside of the bonding line to the housing along a continuous attachment line. The invention also relates to an electron exit window assembly of an electron beam generating device.

In order to improve the performance of an electron-beam device, the ends of the cathode housing is provided with dome-shaped structures.

Electron-beam device

An electron beam emitter comprises a housing enclosing a cathode capable of emitting electrons within the housing and a window for allowing the emitted electrons to exit the housing, wherein the housing has an opening adapted to be at least partly engaged with a high voltage connector assembly, the assembly being adapted to connect the cathode to a power supply, the electron beam emitter further comprising a cooling flange surrounding the opening and having an interior channel extending between an inlet port and an outlet port for receiving cooling fluid for cooling the high voltage connector assembly. The invention further relates to a method of cooling an electron beam device.

An assembly of a support plate and an exit window foil for use in an electron beam generating device. The support plate is designed to reduce wrinkles in the foil. The foil is bonded to the support plate along a closed bonding line bounding an area in which the support plate is provided with a pattern of apertures and foil support portions alternately. When vacuum is created in the housing the pattern is adapted to form a topographical profile of the foil substantially absorbing any surplus foil. Another aspect involves a method in a filling machine for sterilizing a packaging material web.
