Charged particle vortex wave generation

A device (100) for imparting an orbital angular momentum to a charged particle wave propagating along a beam axis (104) in a charged particle beam generating apparatus is described. The device comprises a support element (106) having a target region (108) adapted for transmitting a charged particle wave propagating along a beam axis (104) and an induction means (112) for inducing a magnetic flux along an elongated profile having a free end portion located in said target region (108) and the induction means (112) is adapted for providing a magnetic flux in said elongated profile in order to induce an angular gradient, relative to the beam axis (104), of the phase of the charged particle wave when transmitted through said target region (108). A corresponding method is also disclosed, as well as the use thereof in electron microscopy.
