An apparatus for guiding, in particular directing or accelerating, charged particles (50), comprising: a substrate (110) having a surface (115); an optically thinner layer (120) formed on the surface (115); an inhomogeneous channel (130) which is formed by two mutually opposite delimiting structures on a side of the layer (120) that is opposite the substrate (110); and a radiation device which is designed to generate at least one pulsed laser beam (140) and inject the at least one pulsed laser beam (140) into the channel (130) from a side that is opposite the optically thinner layer (120). The layer (120) for the laser beam (140) is optically thin, and the delimiting structures have a high optical density in comparison with the layer (120). The delimiting structures are designed to guide the particles (50) by means of the laser beam (140) in the channel (130) and alternatingly focus them along the channel (130) and in at least one direction perpendicular to the channel (130).
An apparatus for guiding charged particles, comprising a substrate having a surface;
A method for producing an apparatus for guiding charged particles, comprising a substrate having a surface, a layer formed on the surface, an inhomogeneous channel which is formed by two mutually opposite delimiting structures on a side of the layer that is opposite the substrate, and comprising a radiation device which is designed to generate at least one pulsed laser beam and inject the at least one pulsed laser beam into the channel from a side that is opposite the layer wherein the surface is reflective, such that the surface brings about an at least partial reflection of the at least one laser beam for guiding the charged particles, the method comprising the following steps:
