An electron exit window foil for use with a high performance electron beam generator operating in a corrosive environment is provided. The electron exit window foil comprises a sandwich structure having a film of Ti, a first layer of a material having a higher thermal conductivity than Ti, and a flexible second layer of a material being able to protect said film from said corrosive environment, wherein the second layer is facing the corrosive environment.

Electron exit window foil

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.

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.

Method for assembling an electron exit window and an electron exit window assembly

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.

A sensor is adapted to sense the intensity of an electron beam generated by an electron beam generator and exited from the generator through an exit window along a path towards a target within a target area. The sensor comprises at least one area of at least one conductive layer located within the path and connected to a current detector. The area, or areas, of the at least one conductive layer are shielded from the surrounding environment and from the exit window (and from one another when there are more than one area) by a shield. The shield is formed on the exit window. The sensor forms a part of a sensing system.

A currency bill recycling machine has an input () and output () for receiving and dispensing currency bills; a transport system (); and a detection system () to which bills are fed by the transport system from the input (). The detection system () is adapted to determine the denomination, authenticity and fitness of each bill. A recycling store () and an unfit bill store () are provided to which bills are fed by the transport system (). The detection system () is adapted to cause genuine fit bills to be fed to the recycling store (), and to cause unfit bills to be fed to the unfit bill store (), the transport system being operable to withdraw bills from the recycling store for dispensing via the output ().
