A device for fastening an emitter to a housing comprises a manoeuvre element slidable in a first direction, an activating element slidable in a second, fastening direction that is inclined in relation to the first direction, with the first and second elements are interconnected via at least one cam mechanism. In addition, a fastening element is slidable in the second direction, wherein the activating and fastening elements are interconnected via at least one elastic element. The fastening element is adapted to move, in response to displacement of the manoeuvre element in the first direction, between a fastening position in which it produces a fastening force onto the emitter and an open position in which the fastening force is released.

Device for and method of fastening an emitter

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.

Sensor and system for sensing an electron beam

The present invention refers to a sensor () for sensing an intensity of an electron beam generated by an electron beam generator along a path, the electron beam being exited from the generator through an exit window (). The invention is characterized in that the sensor () comprises a conductor () located within the path and exposed to the exit window (), and an insulating housing () for shielding the conductor (), said housing () being engaged with the exit window () forming a chamber () with said exit window (), and that the conductor () is positioned within said chamber (). The invention also refers to a system for sensing an intensity of an electron beam.

A method for sterilizing at least partly formed packages with electron beam irradiation in a packaging machine involves sterilizing each of at least two at least partially separate areas of the package by way of a respective electron beam sterilizing device, with each of the sterilizing devices being adapted to characteristics of each respective one of the two areas, and also performing a respective relative movement between the package and each of the electron beam sterilizing devices, which movements are adapted for the sterilization of each respective one of the two areas with the sterilizing devices.

Method of sterilizing packages

The present invention refers to a device for electron beam irradiation of at least a first side of a web, the device comprising a tunnel through which the web is adapted to pass, said tunnel being provided with a web inlet portion, a web outlet portion and a central portion adapted to receive at least a first electron beam emitter provided with an electron exit window through which electrons are adapted to be emitted into the tunnel. The tunnel is being angled at least two locations in each of the inlet portion and the outlet portion in such a way that any X-ray formed during the electron beam irradiation of the web is forced to hit the tunnel wall at least twice before exiting the tunnel.
