    Abstract: The present invention relates to a field emission lighting arrangement, comprising an anode and a cathode, where the shape of the cathode is selected based on the shape of a evacuated envelope in which the anode and cathode is provided. The inventive shape of cathode allows for an improved uniformity of an electric field provided between the anode and cathode during operation of the field emission lighting arrangement. The invention also relates to a corresponding method for selecting a shape of such a cathode.

    Abstract: The present invention relates to an x-raysource, comprising a field emission cathode, an anode, connectorsfor allowing application of a high voltage between the cathode and the anode for enabling emission ofanx-ray beam, and an evacuated chamber insideof which the anode and the cathode are arranged, the evacuated chamber having an x-raytransparent window, wherein the field emission cathode consists of a carbonized solid compound foam having a continuous cellular structure, the continuous cellular structure providing multiple emission cites for emission of electrons ontothe anode when the high voltage is applied. The field emission cathode provides for the possibility to increase the efficiency of the x-raysystem as it is possible to in a much higher degree control the electrons emitted by the field emission cathode in terms of switching time, current, kinetic energy and the emission direction.

    Abstract: The present invention relates to a method for controllably growing ZnO nanowires, for example to be used in relation to field emission lighting. In particular, the invention relates to a method of controlling thermal oxidation conditions to achieve steady-state conditions between an oxygen consumption rate by a growing oxide on a surface of a structure and the decomposition rate of the oxygen-carrying species within the chamber. The invention also relates to a corresponding field emission cathode.
