Patent number: 10670670Abstract: The problem addressed by the invention is that of providing a coil having advantageous properties for an oscillating circuit, in particular for a measuring device for electromagnetic signals. This problem is solved in that the coil comprises an electric conductor, the ends of which form the two terminals of the coil. Wound sections of the electric conductor are twisted together, that is to say wound helically around one another. The electric conductor is in principle surrounded by insulation, for example made of plastic or varnish. As a result of the twisting, increases in spacing between adjacent conductor sections within the windings are achieved. This results in an improved quality of the coil.Type: GrantFiled: September 17, 2015Date of Patent: June 2, 2020Assignee: Forschungszentrum Jülich GmbHInventors: Stephan Appelt, Martin Süfke, Bernd Alexander Liebisch

Patent number: 10607804Abstract: The present invention refers to a device for generating charged particle beams with tunable orbital angular momentum. The device firstly includes one or more components for providing a charged particle beam. It is further characterized by an electrical arrangement for imparting a tunable orbital angular momentum to the charged particle beam during operation. The orbital angular momentum of the produced charged particle vortex beam is tunable by adjusting the amount of electrical current. The chirality of the produced charged particle vortex beam is switchable by reversing the direction of the electrical current. The generation of the charged particle vortex beam from the present invention does not depend on the energy of the charged particle beams. The generation of the charged particle vortex beams from the present invention is predictable and reproducible.Type: GrantFiled: September 7, 2016Date of Patent: March 31, 2020Assignee: Forschungszentrum Jülich GmbHInventors: Amir Tavabi, Penghan Lu, Martial Duchamp, Rafal Edward Dunin-Borkowski, Giulio Pozzi

Patent number: 10505513Abstract: The invention relates to a filter circuit which, on the hardware level, prevents charge transfers caused by one or more currents in a frequency divider (200) from generating an interference signal that can cause a signal distortion at the output of a current-to-voltage converter (300) belonging to a filter circuit. This signal distortion would otherwise have to be removed by means of laborious post-processing of the signal. In this process, the voltage curve at the input of the frequency divider (200) or the current at the second output of the frequency divider (200) are employed so that, by means of a compensation circuit arrangement, it is possible to model a compensation signal that essentially compensates for an interference signal caused by the charge transfers. The invention also relates to an associated method.Type: GrantFiled: July 5, 2016Date of Patent: December 10, 2019Assignee: FORSCHUNGSZENTRUM JÜLICH GmbHInventors: Christian Grewing, Markus Robens
