Abstract
Ionisation device, comprising a linear hollow cathode device which has hollow cathode electrodes, defining a main hollow cathode electrode gap in which a magnetic field created by means of magnetic elements is confined; and a gas distribution element in which a gas distribution cavity is arranged providing uniform gas distribution on the main hollow cathode electrode gap with suitable powering which in a substantially vacuum environment would be able to produce a substantially linear plasma discharge which is spatially extended by the relative position of the hollow cathode electrodes and an anode element wherein this extended plasma allowing a wide interaction with particles travelling from a coating material source ionised in order to produce a coating or a plasma treatment on a substrate surface.
