Patent number: 7592613Abstract: 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.Type: GrantFiled: June 14, 2007Date of Patent: September 22, 2009Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Anders Kristiansson, Lars Åke Näslund, Hans Hallstadius, Werner Haag, Kurt Holm, Benno Zigerlig
