Claim 11:
12. A method for guiding charged particles in an apparatus for guiding charged particles, the apparatus 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 a radiation device which is designed to generate at least one pulsed laser beam and inject the at least one laser beam into the channel from a side that is opposite the layer the method comprising the following steps:
injecting the at least one laser beam into the channel from a side that is opposite the layer, onto the layer and the surface, wherein the surface brings about a reflection of the at least one laser beam; thereby guiding the particles in the channel; and
alternatingly focusing the particles along the channel and in at least one direction perpendicular to the channel.
