Abstract: 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.

Abstract: 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.

Abstract: The present invention refers to a sensor (10) 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 (24). The invention is characterized in that the sensor (10) comprises a conductor (26) located within the path and exposed to the exit window (24), and an insulating housing (28) for shielding the conductor (26), said housing (28) being engaged with the exit window (24) forming a chamber (30) with said exit window (24), and that the conductor (26) is positioned within said chamber (30). The invention also refers to a system for sensing an intensity of an electron beam.
